Mary6756--Hi AlisonO, I was diagnosed 35 years ago with IBS and Gerd. In reading about all the gut issues IBS includes, I suspect that I have diverticulosis...My Mother had issues her whole life, and now that I am older, many of her symptoms fit me. I am gluten free (for the most part) and lactose-free as well as acid-free(for the Gerd) These diet changes improved my gut health immensely. In my case, stress causes issues as well. I have had only one bad bout with diverticulitis a little over a year ago, and do not want to go through that again. I started back to eating with cream of rice cereal, bananas, eggs and well cooked vegetables. I don't eat anything pre-packaged, trying to limit preservatives and other unwanted additives. I added things to my diet, like baked or broiled chicken, potato and salad-no tomato, adding 1 thing per week if tolerated. Gradually working up to a balanced diet with the addition of fruit. I have found that any sugars are not in my best interest. I am looking into starting a probiotic for gut health as well. A nutritionist might be of help! You might try a low fod-map diet to see what works for you. There are lots of articles you can read online in regard to this subject. I wish you well, on your road to recovery!!!
