Bowel Health Self-Assessment for Colonic Hydrotherapy
Curious about colonic hydrotherapy and whether it may be suitable for you?
Take Parkland Natural Health’s free bowel health self-assessment to explore your bowel habits, digestive concerns and relevant health information. Your result may highlight a colonic hydrotherapy option to discuss, or advise postponing or reviewing treatment first.
The assessment provides a starting point for discussion, not a diagnosis. A therapist always confirms final suitability during consultation before treatment at our Holborn, London clinic.

Start your bowel health self-assessment
Answer each question as accurately as you can. The assessment may identify a treatment option to discuss, a reason for professional review, or a situation where medical assessment should come first.
How to use your assessment result
Your result is a personalised starting point, not a medical diagnosis or a guarantee that a particular treatment will help. Depending on your answers, it may suggest a standard colonic appointment, a structured option to discuss, a clinic-specific adjunct, or professional or medical review before considering any treatment.
Every appointment includes a consultation before treatment. Your therapist will review relevant health information, ask follow-up questions and confirm whether the proposed procedure is appropriate. If your therapist identifies a contraindication, they will not proceed with treatment.
If you already have a diagnosed gastrointestinal condition, persistent diarrhoea, unexplained rectal bleeding, significant abdominal pain, unexplained weight loss or another concerning change in bowel habit, appropriate medical assessment remains important.
Your result can help you
- describe your current bowel pattern
- identify relevant health and lifestyle context
- see whether treatment needs further review
- explore an appropriate Parkland option to discuss
- prepare useful questions for consultation
How different bowel-health patterns are interpreted
The assessment looks at patterns rather than treating one answer as a diagnosis. It also separates clinic-specific options from situations where medical care should come first.
Constipation and irregularity
Less-than-daily bowel movements alone do not automatically trigger a treatment course. The assessment considers frequency together with stool difficulty, straining, laxative use, reliance on coffee as a bowel trigger and the wider pattern. A structured course may be presented only as an option to discuss, not as a proven way to retrain the bowel.
Loose stools and diarrhoea
The assessment interprets loose stools in context. Persistent or undiagnosed diarrhoea requires medical investigation rather than an automatic treatment recommendation. Where screening is otherwise appropriate, a bicarbonate colonic may appear as a Parkland clinic option to discuss; it is not presented as a scientifically established treatment for diarrhoea, bloating or intestinal Candida.
Recent antibiotic use
Recent or repeated antibiotics are relevant digestive context because antibiotics can alter the intestinal microbiota. The assessment may invite discussion of Parkland probiotic or bicarbonate options, but it does not claim that these restore the microbiome, return normal flora to a previous state or prevent Candida overgrowth.
Cramping and spasm
If cramping is part of the pattern, the assessment may flag an anti-spasmodic herbal option for discussion. Evidence for oral peppermint oil in IBS does not prove the effectiveness of a rectal herbal blend, so this remains a clinic-specific complementary option rather than an evidence-based treatment claim.
IBD, haemorrhoids and rectal symptoms
Active inflammatory bowel disease is treated differently from well-controlled disease without a flare-up. Likewise, uncomplicated haemorrhoids are not an automatic contraindication, while inflamed, bleeding or severely painful haemorrhoids require a different response. The assessment screens rectal bleeding and other red flags separately.
Suspected worm infection
If you report seeing worms, worm segments or eggs, the assessment follows a medical-first route. Pharmacy or GP assessment and established antiparasitic treatment take priority. A Parkland anti-parasite colonic, if shown at all, is presented only as a secondary complementary option after appropriate medical assessment.
Research context & limitations
We believe it is important to separate what published research supports from what is offered as a clinic-specific complementary option. Medical transanal irrigation (TAI) provides useful background evidence for bowel irrigation, but it is not the same intervention as clinic-based colonic hydrotherapy. A 2025 systematic review included 16 studies and 1,567 people, with only one underpowered randomised trial; a 2026 Italian study of 216 adults reported improvements during long-term TAI but was prospective and observational. We therefore do not present these studies as proof that a short course of colonics will retrain the bowel.
The evidence boundaries are also different for adjuncts. Laboratory research on sodium bicarbonate and fungi does not establish that a bicarbonate colonic treats intestinal Candida, diarrhoea or bloating. Research on probiotics after antibiotics remains mixed, and does not directly establish the effect of a rectal probiotic implant after colonic hydrotherapy. Evidence for peppermint oil concerns oral preparations in IBS and does not directly validate a rectal anti-spasmodic herbal blend.
For safety screening, the assessment uses professional contraindication guidance from RICTAT and applies conservative medical-first boundaries where appropriate. Visible worms are handled in line with NHS guidance that pharmacy or GP assessment and established medication may be required.

Safety screening before treatment
Colon hydrotherapy is not suitable for everyone. The online assessment includes questions designed to identify important contraindications and situations that need professional review, including pregnancy, active inflammatory bowel disease, rectal bleeding, certain anticoagulants, uncontrolled medical conditions, chemotherapy, recent abdominal radiotherapy and recent surgery.
The assessment does not apply one universal waiting period after surgery. The assessment distinguishes between different procedures and uses conservative timeframes, while recognising that individual circumstances and written medical support can affect suitability.

Bowel health self-assessment: frequently asked questions
Is this bowel health self-assessment free?
Yes. It is free to complete, requires no registration, and does not require contact details.
Will my answers be stored?
No. The Parkland Health Assessment generates your result while you use the page and does not store your assessment answers.
Does the result mean that I definitely need colonic hydrotherapy?
No. The result identifies a possible next step to discuss. It may also advise professional or medical review instead of treatment. Suitability is confirmed during consultation before any procedure begins.
Can I take the assessment if I have constipation?
Yes. The assessment considers frequency, stool consistency, straining, laxative use and other context. Less-than-daily bowel movements by themselves do not automatically mean that you need a course of treatment.
Can I take it if I have loose stools or diarrhoea?
Yes, but persistent or unexplained diarrhoea needs appropriate medical investigation. The assessment screens for this and does not treat loose stools as an automatic reason to recommend a colonic.
What if I have Crohn’s disease, ulcerative colitis or haemorrhoids?
The assessment asks about the current status rather than using the diagnosis alone. Active inflammatory bowel disease is a contraindication. Controlled disease without a flare-up requires individual assessment. Uncomplicated haemorrhoids are considered differently from inflamed, bleeding or severely painful haemorrhoids.
What if I have seen worms or worm segments?
The assessment follows a medical-first route. Depending on what you have seen and your symptoms, NHS guidance recommends pharmacy or GP assessment and established medication. Colonic hydrotherapy is not presented as a substitute for diagnosis or antiparasitic treatment.
Do I need to complete the assessment before booking?
No. You can book directly. However, completing the assessment first can help you identify useful questions and understand whether a particular option is worth discussing with your therapist.
