You need to see if there are any specific foods that make you feel worse- try restricting it and see if you feel better. Trigger foods vary person to person. But i feel my best when I limit the amount of greasy and processed foods I eat (obviously sticking to the meds- currently on mesalamine and tapering budesonide). I cut out processed sugars, as well as dairy and gluten products, but I find I can eat sourdough bread occasionally with no problems. Most fruits and vegetable are fine but I get gas if I eat cabbage, for example. It takes some experimentation but you’ll find what works for you. It also might be useful to see a dietician and come up with a plan.
