Serious Flaws in Colonic Hydrotherapy Review
An investigation into the references of a recent article published by the Journal of Family Practice shows serious flaws among the evidence and context of the information presented, according to some health experts. Some research was taken out of context, and others appear to be misrepresented in the report.
In one statement made in the article, it says that there is no evidence of hydrotherapy efficacy, while referencing a review article (Richards et al. 2006) that actually states: “there is no clinical evidence that refutes the many clinical reports of efficacy among a myriad of health professionals.”
Furthermore, another study, also referenced in the article, showed that after colonic irrigation on ten patients with or without constipation:
“The number of leukocytes and their demarcation were then evaluated. The number and ratio of lymphocytes increased significantly after irrigation. This result suggested that colon irrigation might induce lymphocyte transmigration from gut-associated lymphatic tissues into the circulation, which may improve colon and immune system function.”
While the article accurately mentions rare adverse effects, the article amplifies the risk of these effects by stating: “Most reports in the literature note a variety of adverse effects of colon cleansing that range from mild (eg, cramping, abdominal pain, fullness, bloating, nausea, vomiting, perianal irritation, and soreness) to severe (eg, electrolyte imbalance and renal failure).” Yet the 2006 review of the scientific research states:
“Although there is little specific literature on colonic irrigations, a review of the literature on related procedures such as enemas and sigmoidoscopies suggests that the risk of serious adverse effects is very low when the irrigations are performed by trained personnel using appropriate equipment.” (Richards et al. 2006)
Out of the five references Dr. Mishori uses for the adverse effects statement, three relate to colonoscopy pretreatments – that use sodium phosphate and polyethylene glycol – rather than natural colon hydrotherapy; another is the reference above (Richards) and the last one is a report of one patient in Malaysia that apparently suffered confusion and memory loss from “acute water intoxicational hyponatremia” (too much water) following an enema (which is not the same as colon hydrotherapy administered by a trained professional).
In one of these references used to substantiate adverse effects from colon hydrotherapy (Abaskharoun et al. 2007), the administration of oral sodium phosphate or polyethylene glycol in preparation for colonoscopy was given to 767 patients by medical doctors in advance of a colonoscopy. Out of these 767 patients who received sodium phosphate or polyethylene glycol, 6.8% of those receiving sodium phosphate suffered from renal (kidney) failure and 8.7% of those receiving polyethylene glycol suffered renal (kidney) failure.
According to the literature, the administration of sodium phosphate and/or polyethylene glycol is not and has never been a practice of natural colon hydrotherapy for the purpose of removing putrefied waste from the colon.
The last of the five references used in the article is a monograph by the Natural Standard website, which states:
“Colon therapy, also called colonic irrigation and colonic hydrotherapy, has been popularized as a holistic health care practice on the basis of the unproven theory that it promotes health by removing toxins and pathogens from the colon. Colon therapy is practiced primarily in alternative health clinics. Colon therapy involves flushing the colon with water in different quantities, temperatures and pressures. There is limited clinical evidence validating colon therapy as a health promotion practice.”
Among these rare reports of adverse effects are tens if not hundreds of thousands of people who receive colon hydrotherapy every year. Just in the UK alone, an estimated 5600 people receive colon hydrotherapy every month. Many licensed health professionals report success using colon hydrotherapy with few if any side effects when performed by a professional.
Some health experts have spoken out against the findings of the article. “I don’t agree there are no benefits,” says Dr. Jamey Wallace, ND, and clinic medical director for Bastyr University’s Center for Natural Health, according to an interview with WebMD author Kathleen Doheny.
“If someone is constipated and they have no other medical diagnosis, it can be very helpful. Colon hydrotherapy can improve bowel function. Certain people should not consider hydrotherapy. Among them are people with colon cancer, ulcerative colitis, and other bowel problems. If a patient is interested in a colonic irrigation they should first see a physician to make sure there are not health concerns that should be addressed medically.”
Others have spoken out on this
The International Association for Colon Hydrotherapy (IACT), which certifies colon hydrotherapists, also spoke out against the article. IACT Executive director A.R. Hoenninger told WebMD that, “Colon hydrotherapy when performed by a trained therapist using FDA registered equipment and disposable speculums or rectal nozzles is safe.”
If we are to abandon a therapy based on the reports of a few adverse side effects, perhaps we might consider other forms of medical therapies, that have more damaging effects first. For example, Carolyn Dean, M.D., N.D., in her book “Death By Medicine” (2005), compiled the following statistics for 2005:
Hospital Adverse Reaction…. 106,000 deaths
Medical Error…. 98,000 deaths
Bedsores…. 115,000 deaths
Infection…. 88,000 deaths
Malnutrition…. 108,800 deaths
Outpatient Adverse Reaction…. 199,000 deaths
Unnecessary Procedures…. 37,136 deaths
Surgery-Related…. 32,000 deaths
Total Annual Deaths…. 783,936 deaths
Furthermore, the Journal of the American Medical Association (Lazarou et al. 1998) reported that in 1994, 2,216,000 Americans were either hospitalized, permanently disabled, or died as a result of pharmaceuticals. According to a nationwide poll conducted by Louis Harris and Associates released in 1997 by the National Patient Safety Foundation and the American Medical Association, an estimated 100 million Americans experienced a medical mistake: 42% of those randomly surveyed. Misdiagnosis and wrong treatments accounted for 40% of those mistakes. Medical medication errors accounted for 28% of these, and medical procedure errors accounted for 22% of these. In a study of four Boston adult primary care practices involving 1202 outpatients, 27% of responders experienced adverse drug events (Gandhi et al. 2003).
