I have the diarrhea almost every day. sometimes i can't hold it. could it be ibs or allergic to gluten. it comes on very sudden. is there anything i can take for this?

Work up needed: Your symptoms are definitely worrisome. While conditions that you have mentioned may result in similar symptoms, they are not likely to cause diarrhea of the intensity you describe. There are meds that might help, such as Imodium or Lomotil, however they will not address the actual cause for your symptoms and that will need to be thoroughly investigated. Talk to your doc first!
