Chronic diarrhea, anxiety, and IBS

User Profile
Shouldn't the Levsin start working immediately? I took one yesterday and one this morning and still had diarrhea. I have taken Lexapro before and it gave me diarrhea. Celexa and Lexapro are in the same drug class so maybe my stomach doesnt tolerate an SSRI? Or the Levsin doesnt work? Is there an SSRI that has a side effect of constipation? And is there an alternative to Levsin?

Chronic diarrhea could be due to IBS but certain other disorders that also cause diarrhea should be excluded first. Such disorders are intestinal infections, malabsorption syndrome, ulcerative colitis, Crohn’s disease etc.

IBS is a functional disorder (has no organic issue) that can be diagnosed when all the organic possibilities are excluded. You need several diagnostic procedures to find the real diagnosis but most valuable in your case would be a colonoscopy and microbiological examination of the stool.

Chances for you to have IBS are good because IBS is related to stress and anxiety and you already suffer from generalized anxiety disorder and panic attacks. It doesn’t seem likely to me that medicines caused your diarrhea. I believe that if you treat your anxiety the IBS will also calm down.
