I was also on a retstricted diet but kept getting obstructions, then read about strictures with Crohns disease, apparently very common and a disease the gastroenterologist actually understand, conduct research on and some specialize in treating (unlike radiation enteritis a very neglected disease). These strictures are often managed with liquid diets, because liquids can usually pass through very narrow strictures. So two years ago I put myself on a liquid diet. No more obstruction, lost weight until I learn more about nutrition and caloric density. Of course if stricture closes off completely then even liquid can't get through. Still was having frequent intestinal spasms, sometimes followed by diarrhea, until learned to use peppermint capsules, similar to IBgard. I am going to have CT enterography soon to better define my current anatomy re intestinal fibrosis and narrowing. Hope to avoid surgery, even if have to go on TPN. But I do understand that surgery may eventually be needed.
