I normally have one bowel movement/day and am very regular. One week ago, I experienced a bout of diarrhea that lasted one day. Since then, I have been having more frequent bowel movements - 2 - 3/day. They are mostly normal looking, just smaller and more frequent. I had a very normal bowel movement this morning, then this evening I had a very loose BM. Should I be concerned? Is it unusual for this kind of disorder to go on for a week? I should add that I was taking 40 mg of Prozac daily and I stopped taking the medication just before this started. Could prozac withdrawal be causing this?
