Frequently asked questions

Colonic irrigation — also called colonic hydrotherapy, colon hydrotherapy, or simply "a colonic" — is a gentle, hygienic cleansing of the large bowel using warm, filtered water. They're all names for the same treatment.

Warm water is introduced into the colon at a controlled temperature and pressure, softening and loosening built-up waste, gas and toxins so the bowel can release them. Your practitioner adjusts the flow throughout and may use gentle abdominal massage to help things along. Roughly 30 to 40 minutes is spent on the machine, and most people allow at least an hour for the visit.

We use a closed system, which means the whole process is sealed — waste passes out through a tube without ever being exposed to the room, so there's no odour and no mess. You stay covered throughout, in a private room with its own ensuite. A closed system also has a viewing tube, so your practitioner can see and explain what's passing as it happens.

It isn't something you do yourself. Every session here is carried out by a practitioner who is also a qualified naturopath, midwife or other allied health professional, and starts with a health screening to check the treatment is appropriate for you. Read more about what happens during a colonic.

A colonic hydrotherapist uses warm, filtered and sterilised water in a closed system to gently loosen and flush built-up waste, gas and toxins from the colon. Rather than running at one fixed setting, your practitioner fine-tunes water flow, pressure and temperature as the session goes, responding to how your body is reacting, and may use gentle abdominal massage to encourage a natural release. That moment-to-moment tailoring is what keeps a session comfortable and gets a better result from it.

Because a closed system includes a viewing tube, your practitioner can also talk you through what they observe as it happens — stool consistency, gas patterns, or signs of dehydration — which often gives useful insight into your digestive health and lifestyle habits.

The whole session is carried out with your privacy, comfort and dignity as the priority. That level of personalised care isn't possible in an open system, particularly a DIY setup, where the water runs at whatever pressure gravity gives you and nobody interprets what's happening.

A closed system is practitioner-assisted and sealed. Warm filtered water is introduced while waste passes out through a closed tube, so the process is odourless, quiet and hygienic — everything stays contained. The treatment is shaped around you as it happens — flow and pressure adjusted to what your body is doing, abdominal massage where it helps, and what passes through the viewing tube interpreted in real time. That means personalised observations about hydration, undigested food or mucus as the session happens.

An open system uses a self-inserted tube and gravity-fed water, with waste released into an open catchment basin beneath the table. You set yourself up and manage it yourself, at whatever pressure the gravity feed happens to deliver. Nothing is adjusted to suit you, nothing is interpreted — and because waste enters an open basin, splashback, noise and odour are likely.

We only use closed-system equipment. Most clients choose it because the session is genuinely tailored to them, and for the cleanliness and privacy that come with it. Read more on closed versus open colonics.

It depends on your needs. Both aim to cleanse the bowel, but they differ substantially in depth, technique and therapeutic benefit.

Colonic hydrotherapy cleanses the entire colon — roughly 1.5 metres — using warm filtered water in a controlled flow through a closed system. It's performed by a trained practitioner who adjusts pressure, monitors your comfort and provides support in real time, and may include abdominal massage. Infusions can be incorporated in later sessions. Advanced techniques such as alternating warm and cool water are sometimes used to stimulate the bowel's natural muscular activity, which may help retrain a sluggish bowel.

Enemas cleanse only the lower colon — the rectum and sigmoid. They're typically self-administered at home using a small volume of fluid, and offer short-term relief for occasional constipation. There's no practitioner guidance, no therapeutic massage, and none of the same bowel-stimulating effect.

Which is better? A colonic is the more comprehensive and therapeutic option, particularly for persistent digestive issues or where you want professional support. An enema suits occasional home use, but lacks the depth and technique of a full colonic.

And what about laxatives or suppositories? They're a different mechanism again. Stimulant laxatives chemically force the bowel wall to contract, and unlike a colonic, prolonged daily use of them can reduce the bowel's natural responsiveness. They have a legitimate place for short-term or GP-directed use, but they don't clear the colon in the way hydrotherapy does, and they're not something to rely on indefinitely without medical advice.

It depends entirely on what you're asking it to do, and it's worth separating the two claims.

On "detoxing" the body: major medical bodies — the Mayo Clinic and Cleveland Clinic among them — don't recommend colon cleansing for detoxification, and there's no good evidence it removes toxins, treats disease or produces lasting weight loss. We agree with them, and we won't make those claims.

On symptomatic relief: this is where the honest case sits. What clients consistently report is feeling less bloated, lighter, and clearer, and easier movements in the following days. Formal evidence here is limited rather than absent — small studies, a lot of anecdote — so we'd describe it as commonly reported rather than proven.

What is well established is that colon irrigation has genuine clinical uses: bowel preparation before colonoscopy, and managing faecal incontinence and severe constipation. The technique isn't fringe; the sweeping detox claims built on top of it are.

If a clinic tells you colonics cure disease, remove heavy metals or clear "impacted waste" from your colon walls, they're overreaching. Read our colonic myth busters for what we think holds up and what doesn't.

Everyone responds differently to a first colonic, and outcomes vary widely — that's completely normal.

Some clients have a significant evacuation and feel lighter and more energised straight away. Others find very little is released, particularly if they're dehydrated or have compacted stool. In that case the body often needs time to rehydrate and relax before it can respond fully, which is why a bigger result frequently comes in the second or third session.

Your first visit is also how your practitioner assesses the way your body responds and decides the best approach going forward. The aim is to ease your system into the process gently rather than force an outcome. Either way, you'll get aftercare guidance to help you get more from future sessions.

Yes — organic coffee (for liver detoxification), alkalising greens, probiotic (to support gut flora) and turmeric (for its anti-inflammatory properties) are all available as optional add-ons, each aimed at a different goal.

Infusions aren't introduced at your first appointment. Your practitioner will want to see how your body responds to a few standard sessions first, then recommend an infusion if it suits your goals. They carry an additional cost when used.

One timing rule worth knowing: an infusion can only be added if your last regular session was within the last 3 months. Beyond that your practitioner no longer has a current enough picture of your health to judge whether one is appropriate. If it's been longer, or you're not sure where you stand, contact us and we'll check with your treating practitioner before you book. See our infusions page for detail on each one.

In the hours before: avoid heavy or greasy meals for at least 3 hours beforehand, since a lighter digestive load supports better results. Skip alcohol and caffeinated drinks, which dehydrate the body and irritate the digestive tract. Stay well hydrated — drinking plenty of water up to about 2 hours before your session helps soften waste in the colon and supports a smoother release.

What to wear: comfortable, loose-fitting clothing, so you can relax during the session and change easily afterwards.

Before you arrive: once your appointment is confirmed you'll receive an email titled "How to Best Prepare for a Colonic". It covers what to eat and avoid in the 24 hours prior, how to support your digestion in the lead-up, and what to bring on the day.

Following these guidelines helps you feel more at ease and get more out of the session.

No, fasting isn't required — and arriving having eaten nothing all day isn't ideal either, since it can leave you light-headed during the session.

On the day: a light meal 2 to 4 hours beforehand works well. Avoid eating or drinking anything substantial in the last 2 hours before your appointment, and keep sipping water up to about that point.

In the 24 hours before: aim for easy-to-digest foods — steamed vegetables, soups, broths and smoothies. Avoid heavy, greasy or processed meals, red meat, alcohol and carbonated drinks. A lighter diet reduces gas and bloating, which makes the treatment more comfortable and more effective.

If your health goals call for more specific preparation, your practitioner will give you tailored guidance.

No referral is needed. You can book directly with any of our certified colonic hydrotherapists — see our team to choose a practitioner, or call reception and we'll match you with the right person.

Your practitioner starts with a confidential health screening covering your medical history, current symptoms and wellness goals. This makes sure the session is appropriate and safe for you, and gives you the chance to ask questions and raise concerns before anything begins.

During the session your practitioner guides you step by step, adjusting the treatment to your comfort. You remain covered with a modesty sheet throughout, in a dedicated hygienic treatment room with an adjoining ensuite so you can freshen up privately afterwards.

Afterwards you'll get individualised aftercare — hydration advice, dietary suggestions, and recommendations for restoring healthy gut flora. Your practitioner will explain what's normal over the following hours and days, including changes to bowel habits and energy levels.

See our new patients page for the full breakdown of a first visit.

It's the question we're asked most often, and almost everyone who asks it tells us afterwards that they needn't have worried.

Practically, here's what removes the awkwardness: the closed system is fully sealed, so there's no odour and no mess — waste passes out through a tube without ever being exposed to the room. You stay covered with a modesty sheet the entire time. The treatment room is private, with its own ensuite so you can freshen up without walking anywhere. And nothing is left for you to work out or operate yourself — your practitioner handles all of it, quietly and matter-of-factly.

And from our side: our practitioners have done this every working day since 1990, across more than 65,500 patient visits. There is genuinely nothing you can do, say or release that we haven't seen many times over. Bowels are simply the subject matter of the job — the same way a dentist thinks about teeth.

Most clients tell us the first five minutes feel strange, and after that it's just another treatment. If you'd like to talk it through before committing, call us on (03) 9388 0080 — our clinic team have heard every question there is, and if it's one only a practitioner should answer, one of them takes it. Not ready to call? Drop us a line and tell us what you need help with.

Not much. Bring a list of any medications and supplements you take, and details of relevant diagnoses or recent procedures — that's what makes the health screening useful.

Everything else is provided: towels, modesty sheet, and an ensuite with the treatment room so you can freshen up privately. Wear loose, comfortable clothing so changing is easy.

If it's your first visit, allow an extra 10 to 15 minutes for the screening and consultation. See our new patients page.

Yes. You're welcome to bring a partner, friend or family member, and they can wait in reception during your session.

Some people find having someone drive them to a first appointment reassuring, though most feel entirely fine to drive themselves home.

Your practitioner remains with you in the treatment room throughout, so you're never left on your own during the session — that's part of what distinguishes a closed system from a self-administered open one.

Most people are surprised by how gentle it is. You may feel a sensation of fullness, or occasional mild cramping during the release phase, but your practitioner continuously monitors and adjusts the pressure to suit your comfort throughout.

That level of control applies to closed systems administered by a qualified practitioner. Open systems — particularly DIY or one-size-fits-all setups — lack the personalised support and real-time adjustment, which can mean more discomfort and a poorer result.

You undress from the waist down only, in private, and you're covered with a modesty sheet for the entire session. Your top half stays clothed throughout.

Exposure is limited to the few seconds it takes to position the tube, which your practitioner talks you through beforehand. Once you're settled, everything is covered — you spend the session lying comfortably on your side or back under the sheet.

Wear loose, comfortable clothing to your appointment so changing is easy, and bring nothing special. The treatment room has its own ensuite, so you change and freshen up privately without leaving the room.

Hygiene is the second thing most people want to know about, after whether it hurts.

The water is filtered and sterilised before it enters the system, and temperature and pressure are regulated by the machine rather than set by hand. Because the system is closed, waste never enters the room at all — it passes from the tube directly into a sealed waste line, which is why the treatment is odourless and why nothing is exposed to the treatment room or to you.

We follow hygiene protocols aligned with national infection control standards, and each client is treated in a dedicated room with its own ensuite.

If you'd like to see the equipment and have the set-up talked through before you book, just ask — we're glad to show you, and we'd rather you booked knowing exactly what's involved. Call reception on 03 9388 0080.

A typical session involves roughly 30 to 40 minutes on the machine, where warm filtered water gently fills and flushes the colon. Most clients then spend another 20 to 30 minutes in the ensuite, as the body often continues to evacuate naturally.

Allow at least 60 minutes for your visit so you're not rushed. For a first appointment, allow an extra 10 to 15 minutes for the health screening and discussion — reviewing your medical history, addressing concerns, and setting out recommendations tailored to you.

Across a full session, usually somewhere between 40 and 60 litres — but that figure is easy to misread, and it isn't all in you at once.

The colon only holds a couple of litres comfortably. A session works as a repeated cycle of gentle fills and releases: a modest volume goes in, is held briefly, then flows out through the sealed waste line, and the cycle repeats. The total is simply the sum of all those cycles.

Fill volume, flow rate and temperature are regulated by the machine and adjusted to your comfort by your practitioner throughout, rather than being set to a fixed number.

Yes. The water is filtered and sterilised before it enters the system, and warmed to close to body temperature — cold water would cause cramping, and water that's too warm is uncomfortable and unsafe.

Temperature is regulated by the machine rather than judged by hand, and your practitioner can adjust it during the session if you'd prefer it slightly warmer or cooler. Some sessions use gentle alternation between warmer and cooler water to encourage the bowel's natural muscular activity, though that's a technique used selectively rather than by default.

Nothing is added to the water in a standard session. Infusions — probiotic, turmeric, alkalising greens or coffee — are optional add-ons introduced only in later sessions. See our infusions page.

It varies enormously between people, and between sessions for the same person — and we'd rather set a realistic expectation than a dramatic one.

Some clients have a substantial release in their first session. Others release comparatively little, particularly if they're dehydrated or have compacted stool, and see more at a second or third visit once the bowel has rehydrated and relaxed. Neither is a problem, and volume is not a measure of how well the session worked.

One thing worth saying plainly: you will not see decades of "impacted waste" or rubbery "mucoid plaque" coming off your colon walls. That doesn't exist — it isn't seen at colonoscopy, and where cleanse products do produce rope-like material it generally comes from the thickeners in the product itself. Any clinic showing you that as evidence of years of build-up is misleading you.

Because we use a closed system with a viewing tube, your practitioner can talk you through what does pass — consistency, gas patterns, signs of dehydration — which is genuinely more useful than volume.

Yes, and many clients choose to. It can be a supportive time, since the body is already in a natural state of shedding.

It's a personal preference. Some women feel more sensitive or emotionally vulnerable during their period and prefer to wait; others find a colonic relieves cramping, bloating and pelvic pressure. Your privacy and dignity are respected either way.

Straight afterwards: most clients report feeling noticeably lighter, less bloated and more energised. Some describe improved mental clarity or a lift in mood. Responses vary though — it's equally normal to feel a little tired, sensitive or even emotional as your body recalibrates.

Over the next 24–48 hours you may notice increased bowel activity, a mild sense of urgency, or changes in stool consistency. That's a natural part of your body continuing to eliminate waste. If your digestion was sluggish beforehand, a colonic can help stimulate more regular movements. It's also common not to have a bowel movement the next day, particularly after a large evacuation during the session — that's normal and temporary.

Hydration matters. Colonics flush water and electrolytes as well as waste, so drink plenty of water through the day, consider electrolyte-rich drinks like coconut water if you feel light-headed, and eat hydrating, fibre-rich foods.

If you're unsure whether something you're experiencing is normal, call us — your practitioner can give you personalised aftercare advice.

Usually within one to three days — but if nothing happens for a couple of days, that's normal and not a cause for alarm. It's the single most common thing clients ring us about, and almost always it needs no action at all.

The reason is simple: a colonic empties the bowel far more completely than a normal movement does. There's then very little in there to pass until you've eaten enough for waste to accumulate and travel the length of the colon again. Waiting two to five days is well within the normal range, particularly after a large evacuation.

What helps things restart: drinking plenty of water, eating regular fibre-rich meals rather than skipping food, and gentle movement such as walking. See our post-session dietary guidance below.

When to call us: if you've had no movement after five days, or at any point you have severe abdominal pain, a fever, persistent vomiting or rectal bleeding. Those aren't expected effects and should be assessed — contact us, or your GP.

Yes — most people return to their regular activities immediately. Listen to your body, though, and rest if you feel you need to.

Yes, most clients resume normal daily activities including driving and work, and many report feeling lighter and more mentally clear.

Everyone responds differently, though. A small number of people feel a bit tired, particularly after a first session — so if it's your first time, it's worth leaving a little breathing room in your schedule.

Light exercise such as walking or gentle yoga is generally fine. Avoid intense physical activity, high-impact workouts, or anything that puts pressure on your abdomen for the rest of the day.

Your body has just had a deep internal cleanse and may need rest to rebalance. If you feel energised, keep it light; if you feel tired, give yourself time.

Your digestive system is in a refreshed and more receptive state afterwards, so what you eat in the following hours genuinely affects how you feel.

For the first 24–48 hours, stick to light, nourishing meals that are easy to digest and rich in natural fibre: steamed or lightly cooked vegetables such as zucchini, carrot, pumpkin and spinach; ripe fruit like banana, papaya, pear and berries; whole grains such as brown rice, quinoa or oats; soups and broths; small amounts of legumes if you tolerate them; and probiotic-rich foods like unsweetened yoghurt, kefir or sauerkraut if they're already part of your diet.

This reintroduces gentle fibre to keep the bowel moving, rehydrates the colon lining, and helps replenish electrolytes and support the microbiome.

Avoid for at least 24 hours: processed foods high in sugar or refined flour, red meat and heavy greasy meals, caffeine, alcohol, and carbonated or sugary drinks.

General tips: eat smaller meals more frequently rather than one large one, drink plenty of water or herbal tea, and simplify your meals if something feels too heavy.

It depends on your current health, your goals, and how your body responds to the first treatment. Some clients feel noticeably lighter after a single session; others benefit from a short series, particularly with long-standing issues like constipation, bloating or sluggish digestion, or as part of a detox or gut reset.

As a general guide:
• First-timers often start with 2–3 sessions spaced a few days to a week apart, to allow a thorough cleanse.
• Liver cleanse, fertility preparation or fasting programs may call for 3–6 sessions.
• Maintenance — monthly or seasonally — suits people supporting long-term gut health, especially through ongoing stress or dietary disruption.

Your practitioner assesses your needs at the initial consultation and suggests a plan based on your history, symptoms and progress. There's no pressure and no hard-selling of packages. Read more on how many colonics it takes to see results.

Colonic hydrotherapy is generally used as part of a broader approach to digestive and overall wellness. It may help relieve symptoms associated with poor gut function, including:

• Bloating and abdominal discomfort — by helping clear trapped gas and built-up waste
• Constipation or irregular bowel movements — by gently rehydrating and stimulating the bowel
• Sluggish digestion — by encouraging motility and waste elimination
• Skin breakouts or dull complexion — skin health is closely linked to digestion and toxin elimination
• Persistent fatigue or brain fog — a build-up of waste may contribute to feeling sluggish or mentally clouded
• Toxin overload — flushing the colon may support the body's natural detox pathways

Many people also fold colonics into detox or cleansing programs, particularly when fasting, juicing or making significant dietary changes.

Individual results vary, and colonic hydrotherapy works best alongside a balanced diet, good hydration and guidance tailored to you. See the full list of conditions we help with.

It's often used as part of a holistic fertility or hormone support plan. By improving elimination and supporting liver detoxification — the liver processes hormones — colonics may help rebalance the endocrine system.

A sluggish digestive system can contribute to hormonal overload, skin issues, PMS, fatigue and difficulties with ovulation or conception. Colonics are sometimes recommended during the preconception phase, though not during the first trimester of pregnancy, to reduce toxic burden and improve nutrient absorption.

Your practitioner can advise when in your cycle treatment is most appropriate, and whether it suits your particular goals. See our pages on hormonal imbalance and PMS symptoms.

Colonics aren't a direct treatment for skin conditions, but many people with acne, eczema or dull skin report improvements after a series of sessions. The likely explanation is more efficient elimination of internal toxins, reducing the load on the liver and on the skin — itself a detox organ.

Combined with proper diet, hydration and gut health support, colonic hydrotherapy may contribute to a clearer complexion. See our page on skin congestion.

There's no good evidence that it does, and we'd never sell it to you on that basis.

Confirmed parasitic infections are diagnosed from stool samples in a laboratory and treated with targeted antiparasitic medication. If you suspect a parasite, the effective path is a GP and a stool test — not a colonic.

We also won't diagnose one by sight. Most intestinal parasites are microscopic. Mucus strands and fibrous plant material passing through a viewing tube can look remarkably like worms, and so-called "rope worms" have been genetically tested and found to be roughly 99% human DNA — shed mucosal material, not organisms.

This matters because the claim is used commercially: a frightening statement about "what we found" converts one visit into an ongoing course of treatment and supplement sales. If any clinic does that to you, leave. Read more on parasites and scare tactics.

You may see a small, temporary drop from the elimination of waste and water weight, particularly if you've been constipated or bloated. It isn't a fat-loss method and shouldn't be treated as a quick fix.

That said, many clients report feeling slimmer, lighter and less puffy afterwards, which can be a useful motivator alongside healthy eating and lifestyle habits.

For a healthy adult who has been properly screened, colonic hydrotherapy is a low-risk treatment. It isn't risk-free, and you should know what the risks actually are before you book.

Common, mild and short-lived: abdominal cramping during the release phase, bloating or gurgling for a few hours, tiredness (most often after a first session), and temporary changes to bowel habits and stool consistency. Some people feel light-headed if they were already dehydrated.

Uncommon but serious: dehydration and electrolyte imbalance, disruption of gut bacteria, irritation of the bowel lining, and — very rarely — bowel perforation. The recognised risk factors for the serious outcomes are excessive frequency, excessive water pressure, unscreened pre-existing bowel disease, and untrained operators. All four are avoidable.

How we reduce them: a full health screening before your first session that rules out the contraindications listed above; a closed system with machine-regulated pressure and temperature rather than hand-set flow; a qualified practitioner in the room for the entire session; and honest advice on spacing rather than encouraging you to come more often than you need.

Be aware of the wider picture. Major medical bodies, including the Mayo Clinic and Cleveland Clinic, don't recommend colon cleansing for detoxification and note there's no good evidence it removes toxins or produces lasting weight loss. We think you should hear that from us rather than find it elsewhere and wonder why we didn't mention it. What clients most consistently report to us is symptomatic relief — less bloating, easier movements, feeling lighter — and that's what we'd suggest you judge it on.

If you have any diagnosed bowel condition, are pregnant, or take regular medication, speak with your GP first. Read more on colonic safety.

Some flushing of gut bacteria does occur — but the fear of "destroying" your microbiome is overstated. It's the most common objection raised about colonics, and it deserves a straight answer rather than a dismissal.

Two things put it in perspective. First, the microbiome is resilient: much of it lives in the mucosal lining and in the small intestine rather than sitting loose in the colon, and populations regenerate from what remains plus what arrives in your food. There's no evidence that occasional colonic hydrotherapy causes lasting depletion in a healthy adult. Second, the effect depends heavily on frequency — an occasional session is a very different proposition to weekly cleansing, which is where the genuine concern lies. It's one of the main reasons we don't encourage clients to come more often than they need.

What we recommend to support recovery: probiotic-rich foods in the days afterwards — unsweetened yoghurt, kefir, sauerkraut, kimchi — plus fibre-rich whole foods to feed the bacteria that remain. A probiotic infusion can also be added in later sessions to introduce beneficial strains directly, though it isn't offered at a first appointment.

If you have a diagnosed microbiome or bowel condition, or you're recovering from a course of antibiotics, raise it at your screening — it changes what we'd advise on both timing and frequency. See post-antibiotic recovery, or our colonic myth busters for the longer version.

No. There's no evidence that colonic hydrotherapy causes the bowel to lose its ability to function independently, and this is one of the most persistent misconceptions about the treatment.

The confusion comes from stimulant laxatives, which are a genuinely different matter. Senna, bisacodyl and similar work by chemically forcing the bowel wall to contract, and prolonged daily use can reduce natural responsiveness. A colonic doesn't act on the bowel chemically at all — it uses water to soften and carry away what's already there, so there's no mechanism by which dependency would develop.

That said, more isn't better. The real argument for restraint isn't dependency, it's fluid and electrolyte balance and gut bacteria — both of which are affected by frequency rather than by any single session. Medical guidance is generally no more than monthly for elective use, which is consistent with the maintenance spacing we recommend.

If you find yourself wanting colonics more often than that to feel normal, the thing to investigate is what's driving the underlying irregularity — diet, hydration, stress, medication or an undiagnosed condition. That's worth a conversation with your practitioner or GP rather than more frequent sessions.

Colonic hydrotherapy is not recommended during the first trimester of pregnancy, because of changes in abdominal pressure and the potential to stimulate uterine activity. We can suggest gentler digestive support for pregnant clients instead — dietary strategies, hydration guidance, and safe herbal support where appropriate.

For children, colonics are generally not performed except in specific health circumstances, and then only with parental consent and careful practitioner evaluation. If your child has digestive issues, we'd recommend starting with a consultation with one of our naturopaths for an age-appropriate plan.

Before: not as a substitute for your prescribed bowel prep. Colon irrigation is used as a bowel-preparation method in some clinical settings, and studies have found it effective and low-risk in that context — but that's a procedure arranged through your specialist, using their protocol. Your gastroenterologist's instructions are what determine whether your colonoscopy can go ahead, and a colonic booked privately alongside them risks interfering rather than helping. Don't book one in the lead-up without asking your specialist first.

After: give your bowel time to recover before booking. The lining is often mildly irritated after the procedure, and if any biopsy or polyp removal was performed there's a healing period during which irrigation isn't appropriate. We'd want written clearance from your specialist and, as a general guide, would not treat within several weeks of a procedure involving tissue removal.

What often is useful afterwards is rebuilding gut flora — bowel prep clears it thoroughly. Probiotic-rich foods, or a naturopathy consultation, are the more sensible next step. See gut flora recovery.

Tell us at screening if you've had a colonoscopy recently or have one booked — it changes what we recommend.

Sometimes — it depends on severity, and it's a screening conversation rather than a yes or no.

Mild, settled haemorrhoids don't necessarily rule treatment out, and easier, less strained bowel movements can be helpful for them. Severe haemorrhoids, active rectal bleeding, or an acute flare are contraindications, and we won't proceed until they've settled or you've been assessed.

Any rectal bleeding you haven't had looked at needs a GP first. Bleeding is commonly from haemorrhoids, but it's also the symptom you don't want to assume about — it should be properly diagnosed rather than attributed. Tell us at screening either way.

We'd generally suggest waiting until you've finished the course.

Antibiotics already deplete gut bacteria substantially, and adding a colonic mid-course compounds that without adding much. If you're unwell enough to need antibiotics, your body is better served by rest.

Afterwards is a different matter, and it's a common reason people come in. Once you've finished the course and are feeling well, a session alongside probiotic support and fibre-rich food is a reasonable part of getting digestion back to normal. A probiotic infusion may be suggested for later sessions. See post-antibiotic recovery.

Always tell us what medication you're on at screening, including anything recent.

Yes. Colonic hydrotherapy is safe for most people, but there are medical conditions where it isn't appropriate. Your practitioner screens for these at your initial consultation.

Red flags include:
• Pregnancy, especially the first trimester
• Severe haemorrhoids, rectal bleeding, or recent bowel surgery
• Inflammatory bowel conditions such as Crohn's disease or ulcerative colitis, in active flare-up
• Diverticulitis
• Uncontrolled hypertension or heart disease
• Kidney disease or electrolyte imbalance
• Severe anaemia, or active cancer treatment
• Unexplained abdominal pain or undiagnosed digestive symptoms

If any of these apply, treatment may be postponed, modified, or not recommended until you've had clearance from your healthcare provider. Your practitioner won't proceed unless it's safe and appropriate.

Always disclose your full medical history before a session — even if a condition seems unrelated to digestion.

Colonic hydrotherapy is not a government-regulated profession in Australia. There's no standardised licensing body overseeing practitioner qualifications or treatment protocols, so quality of care varies significantly between clinics.

All of our hydrotherapists are certified in colonic hydrotherapy through recognised training programs and hold formal qualifications in naturopathy or another allied health field. That broader education matters — it means a deeper understanding of gut function, medical contraindications and post-care planning.

Elsewhere, practitioners may have as little as a short course behind them with no prior healthcare background. Because the industry is unregulated, it falls to you to ask. We'd encourage you to check any practitioner's credentials and look for evidence of health education beyond basic colonic training.

We follow hygiene protocols aligned with national infection control standards, and screen out anyone with known contraindications — including serious risks such as a twisted or inflamed bowel. Performed correctly this is a safe treatment; in the wrong hands it carries real risk.

In the absence of a government regulator, the meaningful external check is membership of a recognised professional association — bodies that set entry requirements, enforce a code of practice and publish a searchable register. Practitioners on our team hold membership of the Australian Traditional-Medicine Society (ATMS), the Massage Association of Australia (MAA) and the Australian Natural Therapists Association (ANTA), and their membership numbers are listed on our team page — ATMS publishes a public register you can search by name and number; MAA and ANTA confirm membership on request instead.

An initial and a regular session cost the same. Your first appointment includes time for a full health screening and consultation at no extra charge.

Optional infusions — probiotic, turmeric, alkalising greens or coffee — aren't introduced until after your first few standard sessions, so your practitioner can see how your body responds first. They carry an additional cost when used.

Current pricing is on our fees page, or call reception on 03 9388 0080.

No. Colonic hydrotherapy isn't claimable through private health insurance, even when performed by a qualified naturopath. Health funds reimburse based on the service provided as well as the practitioner's qualifications, and colonic hydrotherapy isn't an eligible service under any category.

If you have more complex digestive or systemic issues, your practitioner may recommend a separate naturopathy consultation, which may be claimable if your cover includes naturopathy. Those services are billed and coded separately.

We won't issue misleading invoices. Claiming a colonic as something else would be insurance fraud, and misrepresenting services puts both you and your practitioner at risk if your fund audits the claim — which can affect your eligibility for future health, home or car insurance.

Yes. If you're not satisfied with the quality of service during your consultation, we offer a full refund within 7 days of your visit.

What the guarantee covers: professional and respectful care, clear communication and treatment explanations, a personalised approach tailored to your needs, and a welcoming, pressure-free environment.

What it doesn't cover: specific clinical outcomes. Results vary from person to person depending on your condition and health history, how your body responds to treatment, and how closely you follow the care recommendations.

If you're not satisfied, tell us. We'll review your care plan, adjust your treatment if needed, or refer you to another practitioner if that's a better fit. Full detail on our guarantee page.

Ask one question first: what else are they qualified in? A colonic certificate can be obtained in a matter of weeks, and because the field is unregulated in Australia that certificate alone is legally enough to treat you. It tells you someone can operate the equipment. It doesn't tell you they can recognise a contraindication, interpret what passes through the viewing tube, or judge when you should be seeing a doctor instead. A practitioner with a qualification in naturopathy or another allied health field has been taught all three.

The second question: are they a member of a professional association, and what's their membership number? Associations like the Australian Traditional-Medicine Society (ATMS), the Massage Association of Australia (MAA) and the Australian Natural Therapists Association (ANTA) set entry requirements, enforce a code of practice, and run a complaints process an independent operator isn't subject to. ATMS publishes an open register you can search by name and membership number. MAA and ANTA don't — MAA's practitioner search only covers clinic name and suburb, and ANTA's sits behind a member login — so with those two you ask the association directly. A practitioner who won't give you a number has told you something.

Signs of a good practitioner: proper qualifications, ideally with a background in naturopathy or allied health alongside colonic certification. A thorough health screening and informed consent before your first session. Clear explanations without rushing. A clean, private room with an adjoining ensuite, and sterilised or single-use equipment. Regular check-ins during the session to adjust pressure and flow. Respect for your dignity and boundaries, with appropriate draping. Proper before-and-after care advice. And no pressure selling of treatments or supplements.

Red flags: no pre-treatment screening. An unclean room, bathroom or equipment. Lack of privacy or modesty. A dismissive attitude, or being made to feel awkward for asking questions. Too much pressure, or ignoring signs of discomfort. Claims that colonics "cure everything". No professional association membership or formal training.

Be especially wary of parasite claims. Most intestinal parasites cannot be seen with the naked eye — they're detected in stool samples by identifying microscopic eggs, cysts or larvae. Fibrous waste or mucus strands can look like worms, but that resemblance is misleading. Accurate diagnosis needs laboratory testing arranged by a qualified health professional. A responsible practitioner will never diagnose a parasite by sight alone, and if one tries to frighten you into ongoing care with dramatic claims about "what they found", that's a clear sign to walk away.

The full version of this checklist, including the registers you can search, is on how to choose a colonic clinic.

Judge it on things you can verify rather than things a website asserts. Reviews and a professional-looking clinic tell you less than three checkable facts: whether the system is closed with a practitioner in the room throughout, what qualification each practitioner holds besides their colonic certificate, and whether they'll give you an association membership number you can look up.

That last one matters because the field is unregulated in Australia — there's no registration body and no minimum standard, so "qualified" is a word anyone can use. A nationally recognised diploma has a code you can search on training.gov.au and takes years; a private colonic certificate has no code and can be a matter of weeks.
