Hello Doctor, I am a 55 year old woman with type 2 diabetes. I am on metaformin 850mg 2wise a day. I have had constant diarrhea for over 4 years now. Sometimes 5 times a day. I am afraid to leave my house at times, and i have many accidents. I have had a colonocspy and the Doctor found nothing wrong there. The accidents or the feeling that I have to go is whenver i have any slight stress, for example, if i hear bad news, or something scares me, etc. . . can you help?
