I have had diahrrea for months. at times with varying amounts of blood. any suggestions?

Gastroenterologist: This history is very concerning. You should (if not already done so) be seeing a gastroenterologist along with your primary care doctor. This amount of diarrhea and bleeding is serious. You have some type of inflammation either due to infection, inflammatory process or tumor. There may be other causes. Please get in and get seen and checked out as soon as possible.
