The logistics below apply across the colonic hydrotherapy practice worldwide, but local conventions in London may differ — always confirm specifics with the clinic before booking.

What to wear

Loose clothes for before and after — you may feel bloated or tender. The studio provides a gown and draping sheets. You will undress from the waist down but remain covered throughout the session.

Diet the day before

Light diet the day before: soups, cooked vegetables, broths. Avoid red meat, alcohol, processed food, and large meals. Stop eating 2 hours before your appointment.

Arrival and intake

Arrive 15 minutes early for a first visit. A certified practitioner (I-ACT or equivalent) will review your health history, medications, and any bowel or digestive conditions. This is mandatory and saves you from serious complications.

The session itself

Duration: 30–60 minutes. The practitioner inserts a small, sterile, single-use speculum and filtered water flows in at body temperature, then out. You are draped throughout — the practitioner sees only what is necessary. No odour escapes because the system is closed.

After the session

You may have one or two natural bowel movements in the hour after. Drink electrolyte water or coconut water, eat a light cooked meal (soup, rice, steamed vegetables), and rest. Avoid raw vegetables, alcohol, and coffee for 24 hours.

Payment and packages

Single sessions run €60–150. Packs of 3 to 6 are typical. Be wary of long protocol sales — 3 sessions is the standard maximum for non-clinical use.

Absolute contraindications

Pregnancy (any trimester), active Crohn's disease or ulcerative colitis, recent colorectal surgery (under 6 months), diverticulitis flare, bowel obstruction, severe hemorrhoids, recent heart attack or abdominal surgery. (Source: I-ACT — International Association for Colon Hydrotherapy.)

Medical clearance required

History of colorectal cancer, diverticulosis without flare, severe hypertension, chronic kidney disease, anemia. Written physician clearance before booking.

Medications

Blood thinners, recent chemotherapy, high-dose NSAIDs (increased bowel wall fragility). Tell the practitioner what you take.
