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
Stomach noise: What makes my stomach growl?
What makes my stomach growl when I'm hungry?
Answer
from Michael Picco, M.D.
Stomach noise — such as rumbling, gurgling and growling — typically is due to normal digestion. Stomach growling can occur when you're hungry. But it can also occur after eating or between meals when food is passing through your intestines.
Hunger and appetite are controlled by a complex system of hormone-like substances primarily made by your digestive system. When you haven't eaten for a while, these substances are released and cause a part of your brain called the hypothalamus to "switch on" your desire to eat. A message is then sent to your stomach and intestines. This triggers muscle contractions and the release of acids and other digestive fluids — which causes the rumbling, grumbling sounds you hear — as your body prepares for you to eat. The thought, sight or smell of food also can trigger this response.
Sometimes excessive stomach noise can be a symptom of an underlying gastrointestinal disorder, such as irritable bowel syndrome. But in such cases, stomach noise usually is accompanied by other signs and symptoms such as bloating, cramping, diarrhea or excess gas.
