Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that affects the normal functions of the intestines, causing recurrent abdominal pain and discomfort, changes in bowel function, diarrhea and constipation. People with IBS have colons that are more sensitive and react to things that might not bother other people, such as stress, large meals, gas, medicines, certain foods, caffeine and alcohol.

IBS occurs in an estimated one in five Americans, and is more prevalent among women. It usually develops in late adolescence or early adulthood around age 20 and rarely appears for the first time after the age of 50.

Although there is no cure for IBS, experts at UCSF Medical Center offer a number of options for treating and eliminating its uncomfortable symptoms.
