Colon cleansing: Is it helpful or harmful?

I've read many negative things about colon cleansing, but I don't believe any of them. Colon cleansing generally sounds like a good way to clear toxins from your body. What do you think?

Answer

Proponents believe colon cleansing provides health benefits — by removing toxins from their bodies, and boosting their energy and their immune systems. But doctors take a different view.

Although doctors may recommend colon cleansing in preparation for a medical examination of the colon, most don't recommend colon cleansing for better health or to prevent disease. This is because:

• It's unnecessary. Your colon doesn't require enemas or special diets or pills to eliminate waste material and bacteria. It does this naturally on its own.
• It may be harmful. Your colon absorbs water and sodium to maintain your body's fluid and electrolyte balance. Some colon-cleansing programs disrupt this balance, causing dehydration and salt depletion. Long-term or excessive cleansing programs can lead to problems such as anemia, malnutrition and heart failure.

If constipation is your concern, you can help prevent constipation without colon cleansing. Drink plenty of water and eat a diet rich in fiber. The Institute of Medicine offers these daily fiber recommendations:

• 38 grams for men and 25 grams for women 50 and younger
• 30 grams for men and 21 grams for women 51 and older
