Colonics for cleansing or weight loss? Dr. LaPook says no

Let's face it -- not all of us eat healthy all the time, and on top of that, we tend to take in alcohol and other toxins with our diets.

Can a colonic come to the rescue?

Colonics -- sometimes called colon hydrotherapy -- involve a liquid that is inserted into the rectum through a tube to flush out feces from the gut. Enemas, laxatives, supplements and teas can also be used for colon cleansing.

Proponents claim the procedure will rid the body of toxins and prevent gastrointestinal woes. Colonics and enemas have also been touted for weight loss. Some even promote them to combat ailments like asthma, allergies and arthritis.

CBS News chief medical correspondent Dr. Jon LaPook, however, points out that your body already self-cleans naturally when passing stool. Not only that, a colonic can upset the natural balance of bacteria in our guts that help keep us healthy.

As a gastroenterologist, Dr. LaPook says he's frequently asked by his patients and friends whether getting a colonic is a good way stay healthy and lose weight.
