Aug. 1, 2011 -- Colon cleansing, promoted as a natural way to boost well-being, has no proven benefits and may be risky, according to a new report.

Ranit Mishori, MD, a family medicine doctor at Georgetown University School of Medicine, looked at studies that evaluated colon hydrotherapy or irrigation. She also looked at studies of cleansing by the use of laxatives, teas, and other products taken by mouth or inserted into the rectum.

"If you are a healthy human being, there is no reason to detoxify yourself using these concoctions or colon hydrotherapy," Mishori tells WebMD.

"The body is designed to detoxify itself," she says. "There is no need to help the body do that. If you are not a healthy person and have heart disease, diabetes, or kidney disease, definitely don't do that."

The study is published in The Journal of Family Practice.

A spokesman from the International Association for Colon Hydrotherapy (IACT) took issue with the report. "Colon hydrotherapy when performed by a trained therapist using FDA registered equipment and disposable speculums or rectal nozzles is safe," says A.R. "Dick" Hoenninger, executive director of the association.

Colon Cleansing: The Report

Although colon cleansing has been around since ancient times, it became popular in the early 1900s, Mishori writes. By 1919, the American Medical Association had condemned the practice. It fell out of favor.

However, in recent years, it has made a comeback, she says. Proponents say it can improve fatigue and boost energy, among other claims.

"This is something I get asked about every week by my patients," she tells WebMD.

In colon hydrotherapy, the patient lies on a table. Water, with or without other substance such as herbs, is pumped through the rectum via a tube. Waste and fluid are expelled by way of another tube.

The cleansing products may include coffee, herbs, probiotics, enzymes, and other substances. They typically are taken by mouth or inserted into the rectum. 

Mishori found 20 studies published in the last decade. Although the reports show little evidence of any benefit, many studies reported side effects. These include cramping, bloating, nausea, vomiting, electrolyte imbalance, and kidney failure.
