Irritable Bowel Syndrome (IBS) Support Group
Irritable bowel syndrome is a common intestinal disorder that is characterized by bloating, abdominal pain, diarrhea, cramping, and constipation. Typically no abnormalities appear during standard medical testing, and so irritable bowel syndrome is identified by the symptoms. Although irritable bowel syndrome can cause serious discomfort, the intestines are not harmed.

Good luck. I hope the Lexapro gives you relief from the depression and the IBS pain.
some meds are like that. they are designed to treat one thing but an added benefit is it treats another problem. I'm on a blood pressure medicine not for blood pressure but for facial hair growth.
