Study shows colon cleansing may be risky
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.
A spokesman from the International Association for Colon Hydrotherapy (IACT) took issue with the report.
I find it interesting that there is an International Association for a procedure that has never been shown to be effective.
