Irritable Bowel Syndrome
Irritable bowel syndrome (IBS) is a chronic, episodic intestinal disorder characterized by abdominal pain and altered bowel habits. It affects one in seven Americans, although most go undiagnosed. IBS can have a substantial impact on well-being and health, but doctors underestimate the impact the disease can have, particularly the pain and discomfort.
IBS is thought to be caused by a hypersensitivity of the lining of the colon. If you suffer from chronic irritable bowel–type symptoms, such as bloating, abdominal pain, and changes in bowel habits, ask your doctor about getting a formal evaluation for celiac disease. If you have celiac, then go on a strict gluten-free diet. If you do not have the disease, the current recommendation is to first try a healthier diet including more fruits, vegetables, whole grains, and beans, while avoiding processed foods. The reason people may feel better on a gluten-free diet—and therefore conclude they have a problem with gluten—is because they’ve stopped eating so much fast food and other processed junk. If you eat a deep-fried Twinkie and your stomach aches, it may not be the gluten.
If a more healthful diet doesn’t help, try to rule out other causes of chronic gastrointestinal distress. Researchers found that about one-third of people who avoid wheat and/or gluten don’t appear to have gluten sensitivity but, instead, have other conditions, like an overgrowth of bacteria in their small intestines, fructose- or lactose-intolerance, or a neuromuscular disorder like gastroparesis or pelvic floor dysfunction. Only after each of these is ruled out do I suggest people suffering from chronic, suspicious symptoms try a gluten-free diet.
A number of plant foods, such as peppermint oil, kiwi, ginger, cayenne pepper, have been found effective in the treatment of irritable bowel syndrome.

How to Diagnose Gluten Intolerance
After a formal evaluation to rule out celiac disease, those who suspect they might have gluten sensitivity should first try improving their diet and then have other causes excluded before going on a gluten-free diet, since as many as 1 in 3 people who avoid gluten for symptom control end up having a different disease altogether.
