Opinions do vary. Some recommend a high fibre diet, others say too much fibre will make it worse. It seems to be a case of seeing what works for you. DH has had it for the last 6 years at least but it doesn't seem to cause much trouble. The only problem was when he was on massive doses of steroids which caused peritonitis. I think if your MIL eats sensibly and listens to her GP she shouldn't have too much trouble.
