Does colon hydrotherapy hurt?

In general, colon hydrotherapy does not hurt when performed with a certified device and following instructions. The most common feeling is mild pressure or abdominal fullness, similar to the need to go to the bathroom, which eases as water is released.

During the session, mild cramps or intestinal sounds may occur: these are normal signs of water and air moving through the colon. The practitioner (or the user, at home) always adjusts pressure to maintain comfort.

What does a session feel like?

  • Initial phase: gradual introduction of water, with a feeling of fullness.
  • Middle phase: possible urge to evacuate, mild temporary cramps.
  • Final phase: emptying of the colon, often followed by a feeling of lightness and relief.

After the treatment, many people report feeling relieved, lighter and less bloated.

Temporary side effects

The most common side effects are mild and pass within a few hours:

  • temporary abdominal cramps;
  • immediate bloating;
  • feeling cold or sweating;
  • gas or loose stools in the hours following.

These symptoms are usually normal and indicate that the colon is responding to the treatment.

Contraindications: when not to do it

Colon hydrotherapy should be avoided in some situations. The main contraindications include:

  • pregnancy;
  • active inflammatory bowel disease (active Crohn's disease, ulcerative colitis);
  • acute diverticulitis;
  • active gastrointestinal bleeding;
  • severe inguinal or abdominal hernias;
  • recent intestinal surgery;
  • colon or rectal tumours;
  • severe heart failure.

If in doubt, always consult a doctor before starting treatments.
