Dr. Rynne, A little background: Had a gastric bypass about 10 years ago. Have not had any problems related to the surgery and have been able to keep the extra weight off. A few months ago, I noticed that almost immediately after eating, my stomach started to hurt and I had the urge to have a bowel movement. At this point, every time I eat, I need to go to the bathroom. I have very small stools (in diameter). I m wondering if you could help me? Thanks! Jeanne
