Your Colonic Questions Answered!
A closed colonic is a type of colonic hydrotherapy performed by a qualified colonic hydrotherapist using a closed, hygienic system. Warm, filtered, and sterilised water is gently introduced into the colon to help loosen and flush out built-up waste, gas, and toxins. Throughout the session, your practitioner stays with you, carefully adjusting the water flow and pressure to suit your comfort. Gentle abdominal massage may also be used to encourage natural release.
Your practitioner will also discuss any relevant observations during the session—such as stool consistency, gas patterns, or signs of dehydration—which may provide helpful insights into your digestive health or lifestyle habits.
The entire experience is carried out with your privacy, comfort, and wellbeing as top priorities, in a supportive and respectful environment.
⚠️ Please note: This level of care and personalisation may not apply to open colonic systems, particularly those used in unsupervised or DIY scenarios. Open systems typically lack continuous practitioner involvement, which can limit both comfort and clinical feedback.
A closed colonic system is practitioner-assisted and uses a sealed, hygienic setup where warm, filtered water is gently introduced into the colon while waste is simultaneously removed through a closed tube. The practitioner is present throughout, adjusting the flow and pressure to your comfort level, and may provide gentle abdominal massage to assist the release.
Since the system includes a viewing tube, your practitioner can observe the waste being expelled and discuss observations in real time. This allows for personalised recommendations based on visible signs such as hydration, undigested food, or mucus.
The entire process is odourless, quiet, and hygienic, as all water and waste are contained within a closed-loop system—making the experience comfortable and discreet.
In contrast, an open colonic system involves a self-inserted tube and relies on gravity-fed water. The client remains alone during the session, and waste is released into an open catchment basin beneath the table. There is no practitioner present to monitor or guide the process, nor to offer feedback or adjust the treatment in real time.
Because the waste is expelled into an open basin, some splashback, noise, and odour will most likely occur, and the overall hygiene and comfort may be compromised compared to the closed method. There is also no expert interpretation of what’s being released, which limits the opportunity for tailored advice.
Many clients prefer the closed colonic system for its professionalism, cleanliness, practitioner support, and privacy.
Yes, we offer a range of targeted colonic infusions including organic coffee (for liver detox), alkalising greens, probiotics (to support gut flora), and turmeric (for its anti-inflammatory properties). Your practitioner can help you decide which infusion may best support your goals.
Dietary Guidelines
To ensure the most comfortable and effective experience, it’s recommended that you:
Avoid heavy or greasy meals for at least 3 hours before your session, as a lighter digestive load supports better results.
Refrain from alcohol and caffeinated drinks before your appointment, as they can dehydrate the body and irritate the digestive tract.
Stay well hydrated by drinking plenty of water, ideally up to 2 hours before your session. This helps soften waste in the colon and supports a smoother release.
Clothing
Wear comfortable, loose-fitting clothes to your appointment. This makes it easier to relax during the session and change if needed afterward.
Before You Arrive
You’ll receive an email titled “How to Best Prepare for a Colonic” once your appointment is confirmed. It includes tailored tips on:
What to eat and avoid in the 24 hours prior
How to support your digestion in the lead-up
What to bring on the day
Following these simple guidelines can help you feel more at ease and get the most out of your colonic session.
Your qualified practitioner will begin by conducting a confidential health screening to understand your medical history, current symptoms, and overall wellness goals. This ensures the session is tailored to your individual needs and carried out safely. You’ll also have the opportunity to ask questions, discuss any concerns, and receive clear explanations about what to expect — so you feel fully informed and at ease before starting.
During the session, your practitioner will guide you step-by-step, adjusting the treatment based on your comfort. You’ll remain fully covered with a modesty sheet, and your privacy will be respected at all times. The treatment takes place in a dedicated, hygienic room with an adjoining ensuite bathroom, allowing you to freshen up in complete comfort and discretion.
After your session, your practitioner will provide individualised post-colonic care, which may include hydration advice, dietary tips, and recommendations for restoring healthy gut flora. You’re welcome to ask further questions, and your practitioner will explain what’s normal to expect over the coming hours or days — including bowel habits, energy levels, or any minor after-effects.
The goal is to ensure you feel supported, informed, and confident — before, during, and after your session.
No, fasting isn’t required — but for best results, we recommend eating light in the 24 hours before your session.
✅ Aim for easy-to-digest foods like steamed vegetables, soups, broths, and smoothies.
❌ Avoid heavy, greasy, or processed meals, alcohol, and carbonated drinks before your appointment.
A lighter diet helps reduce gas and bloating, making the treatment more comfortable and effective. Your practitioner will provide tailored guidance if further preparation is needed based on your health goals.
Immediate Feelings
Many clients report feeling noticeably lighter, less bloated, and more energised shortly after their session. Some also describe improved mental clarity or a lift in mood—likely due to the release of built-up waste, pressure, and gas from the digestive system. However, individual responses can vary. It’s also completely normal to feel a little tired, sensitive, or even emotional afterward as your body begins to recalibrate and detoxify.
Bowel Movements
Over the next 24 to 48 hours, you may experience:
Increased bowel activity
A mild sense of urgency
Changes in stool consistency
These responses are a natural part of your body continuing to eliminate waste and adjust to the cleanse. For those with previously sluggish digestion, a colonic can help stimulate more regular movements. Conversely, it’s also common not to have a bowel movement the following day, especially after a large evacuation during the session—this is normal and typically temporary.
Hydration & Aftercare
Colonics flush not only waste but also some water and electrolytes, so replenishing fluids is essential.
We recommend:
Drinking plenty of water throughout the day
Including electrolyte-rich drinks like coconut water or a pinch of sea salt in water if you feel light-headed
Eating hydrating, fibre-rich foods such as fruits, vegetables, soups, and herbal teas to support digestion and regularity
If you have any questions or are unsure whether what you’re experiencing is normal, your practitioner is here to help and can provide personalised aftercare guidance.
The number of colonic hydrotherapy sessions you need depends on your current health status, goals, and how your body responds to the first treatment. Some clients feel noticeably lighter and more energised after a single session, while others benefit from a short series, particularly if they’re addressing long-standing issues like constipation, bloating, sluggish digestion, or as part of a detox or gut reset program.
As a general guide:
First-timers often start with 2–3 sessions spaced a few days to a week apart to allow for a thorough cleanse.
Those doing a liver cleanse, or preparing for fertility or fasting programs, may benefit from 3–6 sessions.
Regular maintenance (e.g., monthly or seasonally) can be helpful for those wanting to support long-term gut health, especially if experiencing ongoing stress, dietary disruptions, or skin issues.
Your practitioner will assess your needs during your initial consultation and provide a personalised plan based on your health history, symptoms, and progress. There is no pressure or hard-selling of packages — we tailor your care to what’s appropriate for you.
A typical colonic session involves approximately 30 to 40 minutes on the machine, where warm, filtered water gently fills and flushes the colon. After the session, most clients spend an additional 20 to 30 minutes on the toilet, as the body often continues to evacuate waste naturally.
In total, please allow at least 60 minutes for your visit to ensure you have enough time to complete the process comfortably and unhurried.
For your first appointment, allow an extra 10 to 15 minutes for a detailed health screening and discussion. This includes reviewing your medical history, addressing any concerns, and providing personalised recommendations tailored to your needs.
Everyone responds differently to their first colonic session, so outcomes can vary widely—and that’s completely normal.
Some clients experience a significant evacuation and feel lighter, less bloated, and more energised right away. Others may find that very little is released, especially if they’re dehydrated or have compacted stool. In these cases, the body often needs time to rehydrate and relax before it can respond fully, which is why greater results may occur in the second or third session.
Your first visit also serves as a chance for your practitioner to assess how your body responds and determine the best approach moving forward. The goal is to ease your system into the process gently and safely—without forcing outcomes.
Whether you experience an immediate release or a more gradual response, your practitioner will support you throughout and provide aftercare guidance to help you get the most from future sessions.
Colonic hydrotherapy is often used as part of a broader approach to digestive and overall wellness. It may help relieve a range of symptoms associated with poor gut function, such as:
Bloating and abdominal discomfort – by helping to 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 – as skin health is closely linked to digestive health and toxin elimination
Persistent fatigue or brain fog – as a build-up of waste and toxins may contribute to feeling sluggish or mentally clouded
Toxin overload – by flushing the colon, which may support the body’s natural detox pathways
Many people also incorporate colonic hydrotherapy into detox or cleansing programs, particularly when fasting, juicing, or making significant dietary changes. It’s valued not just for symptom relief, but for its role in supporting a healthier gut environment, which may contribute to improved nutrient absorption, immune resilience, and overall wellbeing.
As always, individual results can vary. Colonic hydrotherapy is best used in combination with a balanced diet, adequate hydration, and professional guidance tailored to your specific needs.
✅ Signs of a Good Colonic Hydrotherapist
Proper qualifications: They are certified and trained in colonic hydrotherapy, ideally with a background in naturopathy, nutrition, or allied health.
Professional consultation: They begin with a thorough health screening and informed consent before your first session to ensure it’s safe and appropriate.
Clear communication: They explain the process in a way that’s easy to understand and take time to answer all your questions without rushing.
Privacy and hygiene: The treatment is done in a clean, private room with an adjoining ensuite, and all equipment is sterilised or single-use.
Focus on your comfort: They check in with you regularly during the session and adjust pressure or flow to ensure you’re comfortable.
Respectful demeanour: They uphold your dignity and boundaries at all times, using appropriate draping and professional conduct.
Pre & Post-treatment support: They provide before treatment and aftercare advice on hydration, nutrition, and what to expect in the hours or days following the session.
No pressure selling: They don’t push unnecessary treatments, supplements, or fear-based sales tactics.
🚩 Red Flags to Watch Out For
❌ No pre-treatment screening: Skipping a health history or intake form is a major warning sign.
❌ Unhygienic environment: The room, equipment, or bathroom looks unclean or unprofessional.
❌ False Claims about parasites with lab testing:
Be cautious of any practitioner who claims they can identify parasites during a colonic session.
Most intestinal parasites are not seen with the naked eye. They’re typically detected in stool samples by identifying microscopic eggs (ova), cysts, or larvae — not adult organisms. While some fibrous waste or mucus strands may look like worms, this visual resemblance is misleading. Accurate diagnosis requires proper laboratory testing, such as microscopy or PCR, arranged by a qualified health professional like a naturopath or GP.
Unfortunately, some underqualified operators — often with no formal health science background — use these misinterpretations to scare clients into unnecessary repeat sessions or expensive product purchases. These tactics are not only unethical, they may delay proper medical treatment and erode trust in the therapy.
💡 Adult parasites (such as worms) usually remain in the intestines or tissues. What’s released in stool are their microscopic by-products — not the parasite itself. That’s why stool analysis by a certified pathology lab is the only reliable way to confirm a parasitic infection.
✅ A responsible practitioner will never diagnose a parasite by sight alone. If an infection is suspected, they’ll refer you for stool testing — not make dramatic assumptions in the treatment room.
🚫 Red flag: If a practitioner tries to frighten you into ongoing care with vague or dramatic claims about “what they found,” it’s a clear sign to walk away — and consider leaving a Google review to help protect others. Want to know how to spot these tactics and what you can do about them? Click on Parasites & Colonic Scare Tactics: What You Need to Know.
❌ Lack of privacy or modesty: If you’re not kept covered or your dignity is not respected, walk away.
❌ Dismissive attitude: They rush through the process, don’t explain things clearly, or make you feel uncomfortable for asking questions.
❌ Improper technique: Using too much pressure, ignoring signs of discomfort, or lacking awareness of contraindications.
❌ Overpromising results: Be cautious of anyone claiming colonics “cure everything” or making exaggerated health claims.
❌ No professional affiliation: They’re not part of any recognised association or haven’t had formal training in colonic therapy or a related health field.
A good hydrotherapist isn’t just about technique—they create a safe, respectful, and empowering environment that supports your overall wellbeing. Trust your instincts: if something feels off, you’re within your rights to ask questions or walk away.
No referral is needed. You can book directly with one of our certified colonic hydrotherapists.
Most people are surprised by how gentle the experience is. While you may feel a sensation of fullness or occasional mild cramping during the release phase, your practitioner continuously monitors and adjusts the pressure to suit your comfort. You’re in professional hands every step of the way.
⚠️ Please note: This level of care and control typically applies to closed colonic systems administered by qualified practitioners. In contrast, open colonic systems—especially DIY or “one-size-fits-all” programs—may lack personalised support and real-time adjustments, which can lead to discomfort or suboptimal results.
The cost of an initial and regular colonic session is the same, as every session includes a thorough, personalised approach. Your first appointment also allows time for a comprehensive health screening and consultation, but there’s no extra fee for that.
Optional colonic infusions—such as probiotics, turmeric, alkalising greens, or coffee—are not introduced until after your first few standard sessions. This allows your colonic practitioner to assess how your body responds to a regular colonic before recommending any add-ons. Infusions incur an additional cost if and when they are used.
For current pricing, please check our fees page or call reception on 03 9388 0080. You’ll also receive clear preparation instructions to ensure you get the best outcome from your session.
Unfortunately, colonic hydrotherapy is not claimable through private health insurance — even if performed by a qualified naturopath. Health funds reimburse based on the type of service provided, not the practitioner’s qualifications. Colonic hydrotherapy is not an eligible service under any category, and claiming it as something else (such as naturopathy) would be considered insurance fraud.
If you have more complex digestive or systemic issues, your colonic hydrotherapist may recommend a separate naturopathy consultation, which may be claimable if your cover includes naturopathy. These services are billed and coded separately.
Please understand that we cannot and will not issue misleading invoices. Misrepresenting services could place both you and your practitioner at risk, especially if your health fund conducts an audit. This may affect your eligibility for future health, home, or car insurance policies.
We appreciate your understanding and are committed to honest, transparent care.
Colonic hydrotherapy is not currently a government-regulated profession in Australia, which means there is no standardised licensing body overseeing practitioner qualifications or treatment protocols. As a result, the quality of care can vary significantly from one centre to another.
At our clinic, all colonic hydrotherapists are not only certified in colonic hydrotherapy through recognised training programs, but also hold formal qualifications in naturopathy, nutrition, or other allied health fields. This additional education provides a deeper understanding of gut function, medical contraindications, and post-care planning — allowing for safer, more effective treatment.
Unfortunately, many other centres may employ practitioners with minimal training — sometimes as little as a short course with no prior healthcare background. Because the industry is unregulated, it’s up to the client to ask the right questions. We strongly encourage you to check your practitioner’s credentials and look for evidence of broader health education beyond basic colonic training.
At our clinic, we follow strict hygiene protocols that align with national infection control standards and are members of respected professional associations. We also take screening seriously and exclude anyone with known contraindications — including serious risks such as a twisted or inflamed bowel, which could be dangerous if overlooked.
Colonic hydrotherapy is a powerful treatment when performed correctly — but in the wrong hands, it can carry risks. Choose wisely. Not all practitioners or systems (such as unsupervised “open” systems) offer the same level of care or safety.
Yes — colon hydrotherapy is often used as part of a holistic fertility or hormone support plan. By improving elimination and supporting liver detoxification (which processes hormones), colonics may help rebalance the endocrine system.
A sluggish digestive system can contribute to hormonal overload, skin issues, PMS, fatigue, and even difficulties with ovulation or conception. Colonics are sometimes recommended during the preconception phase (but not during first trimester pregnancy) to help reduce the toxic burden and improve nutrient absorption.
Your practitioner can guide you on when in your cycle colonic therapy is most appropriate and whether it’s suitable for your fertility or hormone-related goals.
Colonic hydrotherapy is not recommended during the first trimester of pregnancy due to changes in abdominal pressure and the potential to stimulate uterine activity. However, we can suggest gentler digestive support options for pregnant clients, such as dietary strategies, hydration guidance, and safe herbal support when appropriate.
For children, colonics are generally not performed unless under specific health circumstances, and only with parental consent and careful practitioner evaluation. If your child is experiencing digestive issues, we recommend starting with a consultation with one of our naturopaths or nutritionists for a more age-appropriate plan.
Yes. While colonic hydrotherapy is generally safe for many people, there are certain medical conditions and situations where it may not be appropriate. These are considered red flags, and your practitioner will screen for them during your initial consultation.
Red flags include:
Pregnancy (especially in 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-ups)
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 to you, colonic hydrotherapy may be postponed, modified, or not recommended until you’ve received clearance from your healthcare provider. Your safety is the top priority, and your practitioner will never proceed unless it is considered safe and appropriate.
⚠️ Always disclose your full medical history before undergoing a colonic session—even if a condition seems unrelated to digestion.
It depends on your needs and goals. While both aim to cleanse the bowel, they differ greatly in depth, technique, and therapeutic benefits.
🔹 Colonic Hydrotherapy (Colonics)
Cleanses the entire colon (approximately 1.5 metres)
Uses warm, filtered water in a gentle, controlled flow via a closed system
Performed by a trained practitioner who adjusts pressure, monitors comfort, and provides real-time support
May include abdominal massage to enhance natural release
Can incorporate infusions (e.g. probiotics, coffee, herbal blends) in later sessions
Advanced techniques such as alternating warm and cool water are sometimes used to stimulate the bowel’s natural muscular activity—causing it to contract and relax, which may help “retrain” a sluggish or unresponsive bowel
Often used during detox programs or for chronic issues like bloating, sluggish digestion, or constipation
🔹 Enemas
Cleanses only the lower part of the colon (rectum and sigmoid)
Typically self-administered at home
Uses a small volume of fluid (e.g. water, saline, coffee)
Provides short-term relief for occasional constipation
Does not offer the same level of stimulation or retraining to the bowel
No practitioner guidance or therapeutic massage involved
✅ Which is better?
A colonic offers a more comprehensive and therapeutic approach, especially if you’re dealing with persistent digestive issues or want professional support.
An enema may be suitable for occasional home use but lacks the depth, technique, and bowel-stimulating benefits of a full colonic.
Yes, most people can return to their regular activities immediately. However, it’s advisable to listen to your body and rest if you feel the need.
Colonics may result in a small amount of temporary weight loss due to the elimination of waste and water weight—especially if you’ve been constipated or bloated. However, it’s not a fat-loss method and shouldn’t be viewed as a quick fix. That said, many clients report feeling slimmer, lighter, and less puffy after a session, which can be motivating when combined with healthy eating and lifestyle habits.
Yes, most clients can resume normal daily activities, including driving and going back to work. In fact, many people report feeling lighter and more mentally clear. However, it’s important to note that everyone responds differently. A small number of people may feel a bit tired, especially after their first session, so if it’s your first time, consider giving yourself a bit of breathing room in your schedule.
Yes, you can have a colonic during your menstrual cycle, and many clients choose to do so. In fact, it can be a supportive time, as the body is already in a natural state of shedding and detoxifying.
That said, it’s a personal preference. Some women feel more sensitive or emotionally vulnerable during their period and prefer to wait, while others find that a colonic relieves cramping, bloating, and pelvic pressure. Your practitioner will ensure your privacy and dignity are respected at all times.
Light exercise such as walking or gentle yoga is generally fine after a colonic. However, it’s best to 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 undergone a deep internal cleanse and may need a bit of rest to reset and rebalance. Listen to your body—if you feel energised, keep things light; if you feel tired, give yourself time to rest.
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. This is likely due to the body eliminating internal toxins more efficiently, which can reduce the load on the liver and skin (another detox organ). Combined with proper diet, hydration, and gut health support, colon hydrotherapy may contribute to a clearer, healthier complexion.
After a colonic, your digestive system is in a refreshed and more receptive state, so what you eat in the hours that follow can significantly influence how you feel and how well your body responds.
Recommended Foods (First 24–48 Hours):
Stick to light, nourishing meals that are easy to digest and rich in natural fibre to support healthy bowel function. Good options include:
Steamed or lightly cooked vegetables (e.g. zucchini, carrots, pumpkin, spinach)
Fresh fruits (ripe bananas, papaya, pears, apples, berries)
Whole grains like brown rice, quinoa, or oats
Soups and broths (vegetable or bone broth are ideal)
Legumes in small amounts (e.g. lentils, chickpeas) if tolerated well
Probiotic-rich foods such as unsweetened yoghurt, kefir, sauerkraut, or kimchi (if already part of your regular diet)
Eating this way helps:
Reintroduce gentle fibre to keep the bowel moving
Rehydrate the colon lining
Replenish electrolytes and support the gut microbiome
What to Avoid (for at least 24 hours):
To protect your freshly cleansed system and avoid irritation:
❌ Processed foods (especially those high in sugar, refined flour, or preservatives)
❌ Red meat or heavy, greasy meals
❌ Caffeine, which can dehydrate the bowel
❌ Alcohol, as it may irritate the gut lining and disrupt electrolyte balance
❌ Carbonated or sugary drinks
General Tips:
Eat smaller meals more frequently rather than one large meal.
Drink plenty of water or herbal teas to stay hydrated.
Listen to your body—if something feels too heavy or causes discomfort, pause and simplify your meals.
A calm, gentle reintroduction of food not only supports your digestive recovery but can also prolong the benefits of your cleanse—helping you feel clearer, lighter, and more energised in the days ahead.
