Because of diabetes, my doctor had me taking metformin for many years. He warned me that it would cause diarrhea, as that was one of the ways that it helped to shed blood sugars. After he switched me to janumet (januvia + metformin) I was surprised to learn from my doctor that it shouldn't cause diarrhea, but I was still having it.
So after researching IBS and working on my diet, I found that I can pretty much eliminate my IBS-d woes by avoiding:
- spicy foods
- oily foods (fast food particularly, but even microwave popcorn, which have oils in the bag)
- cruciferous vegetables like cabbage, cauliflower, asparagus etc.
- apples, apple sauce and juices (rich in fructose)
- pears (rich in fructose)
Additionally, I have to be careful with (black) coffee. When I know that I am home for the morning, I do enjoy my morning coffee. I'm not sure about tea, since I don't have it that often but probably the same applies.
