Awash in Speculation
More Than an Enema

When Hank Fry of Columbus, Ohio, entered his 40s, he took stock of his health and decided to make a few changes. "One of my goals is to play golf on my 100th birthday," says the business consultant. So he began exercising more and studying spirituality.
So far so good, most doctors would say. Then as Fry turned 50, he added a new practice for rejuvenation that has yet to gain the endorsement of any mainstream medical organization: colon hydrotherapy (also known as colonics or high colonic) -- a deep-cleaning water treatment for the colon. Fry bought a home colonic kit off the Internet and gives himself a treatment every six weeks.
Fry is one among many. Due in part to vigorous Internet promotion, colonics are growing increasingly popular. And that has some doctors concerned. Not only is there scant evidence of any health benefits, but also the practice could be dangerous.
Growing popularity
Colon hydrotherapy dates back to biblical times. No one is certain how many people employ this practice today -- either via home treatments or via outside clinics -- but many in the field say the numbers are increasing, along with overall interest in alternative health practices.
"It's exploding around the world," says Dick Hownninger of the International Association for Colon Hydrotherapy, based in San Antonio, Texas. The association has more than 800 members, up from just 100 members in 1996. Most are colon therapists, who administer treatments.
The treatment
Colon hydrotherapy methods differ, but most follow the same basic procedure. The colon is filled with cool or warm water through a tube inserted into the rectum. After several seconds to a few minutes, the water and any fecal matter are drained through a second tube. This process is repeated several times in one treatment. Sometimes minerals are added to the water.
Most people administering colonics today use disposable, sterile tubing, and machines regulate the temperature and pressure of the water. Colon hydrotherapy itself is not regulated, although the association of colon hydrotherapists runs a voluntary certification program, as do several machine manufacturers.
Even among colon hydrotherapists there are different opinions on what benefits can be derived from the procedure. Some say that simply flushing out old fecal matter promotes energy and wellness. Others are more specific.
