Irritable bowel syndrome

Irritable bowel syndrome, or IBS, is a chronic or reoccurring series of gastrointestinal symptoms that often causes distress for those who have it. IBS is associated with a group of symptoms that affect the large and small intestines. It is estimated that IBS affects 10% to 15% of adults worldwide. Though no specific cause is known, several factors may contribute to IBS, including genetics, certain mental health disorders, food sensitivities or intolerances, infection or a change in intestinal bacteria type or amount. Certain foods and stress may trigger symptoms; diet changes, stress management and a healthy, active lifestyle may help manage IBS.
