Why do i have problems digesting anything?

Don't worry about the endoscope. My daughter has had two as a teenager and they are no big deal at all. You could try probiotics in a pill form. They won't hurt and may help get the good bacteria back up and functioning in your bowels. The previous persons comment about the gall bladder is a good one too. Avoid anything processed, try to eat simple plain foods, like rice and bananas. DON"T eat milk products! Lactose is always hard for adults to digest.
