<p><strong>What Is Irritable Bowel Syndrome?</strong></p>
<p>Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder in the United States. It is characterized by intermittent periods of constipation or diarrhea and often pain or bloating. After partly digested food leaves the stomach, it is moved through the small and then the large intestine by regular contractions (peristaltic motility) of the muscles in the intestinal wall. In IBS, these muscles may go into spasm and move residues either too quickly (causing diarrhea) or too slowly (causing constipation). IBS should not be confused with the more serious inflammatory bowel diseases.</p>
<p>There is no cure for IBS; treatment focuses on relief of symptoms, which can often be accomplished with a combination of diet and stress management. Medications are also sometimes helpful. IBS is more common in women than men, and symptoms may worsen in relation to menses.</p>
