Colon cleanses using natural ingredients can cause damage, states Cleveland Clinic. Liver poisoning and aplastic anemia are linked to using herbal preparations in colon cleanses. Cleansing with herbal products leads to electrolyte imbalances and kidney failure in serious cases and cramping, nausea and vomiting in milder cases, reports Time Magazine.
Patients who have undergone cleanses may experience perforated rectums, abscesses, fullness and bloating, notes Cleveland Clinic. Patients with colitis, diverticulitis, Crohn’s disease, or heart or kidney disease should avoid colon hydrotherapy. Colon cleansing heightens the risk of pancreatitis, infection, heart and kidney failure for these individuals. Anyone who chooses to undergo a colon cleanse should ensure that the International Association of Hydrotherapy or the National Board of Colon Hydrotherapy has certified the practitioner.
