Hi Lillian,   Many of us IBDers find that what we eat can help our symptoms or make them worse. Before you dash off to a nutritionist, have your mother keep a food diary - you can read some of my Shareposts on the main IBD site about doing this - which will help her to see if what she is eating is causing some of her issues. It's best to keep this kind of diary for at least 2 weeks, a month is even better. Obviously, if you find a particular food or category of foods that are troublesome have her stop eating them for a few days or a week and see if that helps.   As we age, what our guts can tolerate can become quite finicky, so she may be eating things that weren't a problem a few years ago but are now causing some symptoms.   She also should let her doctor know about any symptom changes that are significant.   Best of luck to her, Elizabeth
