Irritable Bowel Syndrome: Mark Pimentel, MD
Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder, affecting 10-15% of the world’s population. Approximately two-thirds of those who suffer from IBS are women. The disease can have mild forms or cause severe debilitation as diarrhea alternates with constipation. Severe cramping and bloating also are common. Because chronic IBS is so debilitating, it often disrupts the daily lives of people with this disorder.
