Dr. Michael F. Picco has been with Mayo Clinic since 1999. He is board certified in internal medicine and gastroenterology. Dr. Picco is an assistant professor of medicine at Mayo Clinic College of Medicine and a consultant in gastroenterology at Mayo Clinic in Florida.
He has authored numerous publications in the area of gastroenterology, including original research, editorials and textbook chapters. He works with a team of gastroenterologists that takes care of complex gastrointestinal conditions and has a particular interest in diarrheal illnesses and inflammatory bowel diseases (ulcerative colitis and Crohn's disease). He is also active in medical education in training new gastroenterologist and internists.
"MayoClinic.com is an invaluable resource for patients and their families," Dr. Picco said. "Informed patients are better able to participate in their own health care. A patient's participation is vital to the treatment of his or her disease. I hope to assist in helping patients understand their digestive problems and current treatments that are offered. This will allow for better communication between patients, their physicians and other health care professionals."
Dr. Picco serves as a reviewer of new research for several medical journals in the area of gastroenterology and is an active member of the American Gastroenterological Association, American College of Gastroenterology and the Crohn's & Colitis Foundation of America. He serves on numerous committees that address physician training, research and clinical practice in gastroenterology, both at Mayo Clinic and at the national level.
"Patients need to know about their disease, what to expect, the latest treatments and side effects so that they can make informed decisions about their health care. Gastrointestinal disease affects not only patients but also their families. My goal is to assure that our Web site provides accurate, reliable information and resources for patients. We must always provide the latest, most cutting-edge information to assist patients in dealing with their medical problems," Dr. Picco said.

Question
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
from Michael Picco, M.D.
Proponents of colon cleansing believe that toxins from your gastrointestinal tract can cause a variety of health problems, such as arthritis, allergies and asthma. They say that colon cleansing — also called colonic irrigation — removes these toxins, thus promoting healthy intestinal bacteria, boosting your energy and enhancing your immune system.
While there is little scientific evidence to support or refute the benefits of colon cleansing, critics say it's generally unnecessary and at times may even be harmful. Although doctors prescribe colon cleansing as preparation for medical procedures such as colonoscopy, most don't recommend it for detoxification. Their reasoning is simple: The digestive system and bowel naturally eliminate waste material and bacteria — your body doesn't need enemas or special diets or pills to do this.
One concern with colon cleansing is that it can increase your risk of dehydration. A potentially more serious concern is that certain laxatives used in colon cleansing, such as those with sodium phosphate, can cause a rise in your electrolytes, which can be dangerous if you have kidney disease or heart disease.
If you choose to do colon cleansing, be sure to take these simple precautions:
- Check with your conventional medical providers first, especially if you take any medications or have any health problems.
- Make sure your colon-cleansing practitioner uses disposable equipment that hasn't been previously used.
- Get a list of specific herbal ingredients and amounts in any colon-cleansing products you use — some herbal supplements can cause health problems.
- Beware of broad or inflated claims that colon cleansing will cure an illness or improve your health.
- Stay well hydrated by drinking lots of fluids while undergoing colon cleansing to prevent dehydration.
If you are considering colon cleansing because of constipation, consider trying these steps first to relieve constipation:
- Drink plenty of fluids, including water
- Eat a diet rich in fiber
- Get regular exercise
