Diarrhea and weight loss

[Warren9]

I have had chronic diarrhea for 4 months and have lost 30 lbs. I have had a stool analysis and a colonoscopy with normal results. I also had antibiotic treatment(10 days) with no impact on situation. Type of food or drink dosen't seem to matter. Immodium helps. What should I do next?

Welcome to the gastroenterology community!  I would recommend that you try eliminating all lactose from you diet for 2 weeks to see if that helps.  You can also try eliminating all gluten from your diet for 2 months.  You should also definitely see a gastroenterologist about this.
