Suggest Treatment For Constant And Frequent Diarrhea

I have had diarrhea for the past 2 weeks averaging going 12-15 times a day plus through the night. I only get about 15 seconds to get to the bath room because I can no longer hold it & have had a few accidents. I m going to see my doctor tomorrow. I m 65, & take meds for diabetis, thyroid, blood pressure & cholesterol? Any suggestions?
