When I was first diagnosed, I was already eating bland foods. I was having a lot of chicken broth, as well. I was told white rice, things made with white flour like pancakes, white bread. Smaller amounts of food several times a day instead of big meals help. After taking Prednisone and the flare-up calmed down, I was given a copy of the FODMAP diet. It was suggested to integrate small amounts of vegetables at a time, one kind at a time and monitor which veggies worked and which ones didn't. Right now the more bland and liquid diet makes sense to give your husband's intestine a chance to rest and calm down. I hope this helps.

Thank you so much for your reply. I really appreciate the information. I am just getting into finding information etc. we will find out more once we see the surgeon this week.
