Hello @shortiseltzer and welcome to Mayo Connect. As you can see, Mayo Connect is a great way to learn from the experiences of others. You are probably glad to find the reason for the diarrhea and weight loss.

While you wait for the biopsy results, you might try keeping a food diary, as suggested by @shelleyw. This might give you some clues as to any foods that are triggers for diarrhea.

I look forward to hearing from you again. I hope you will continue to share your journey with this diagnosis. When do you expect to get the biopsy results?
