My situation differs, but diet problems are likely the same. After removing my colon, my surgeon said, "You have, now, the equivalent of a newborn infant's intestinal system. You'll learn what works. First, avoid salads: lettuce of every hue is chiefly water, shouldn't bother, but does, and offers little. Don't eat after 5 p.m. Introduce foods gradually as you did to babies." Everything he said proved true.
