I also had diverticulitis, but last April had 18” of it removed. Finally healing, as I also was diagnosed with Hashimoto’s/Hypothyroidism and Hashimoto’s was off the charts when testing my PTO Antibodies. This test was done on me while checking my TSH (Thyroid) levels. They were off the charts high and I’ve since gone Gluten-Free, Dairy Free and Soy Free. Feeling much better and I’m also in the process of seeing a Functional Medicine Doctor and having my food allergies tested. I’m hoping to find out more foods that I’m allergic to so that I can stop eating them and feel even better. I’m sorry you’re suffering, but I would try eliminating those three foods I mentioned above and I’m going to bet that you’ll feel better. Feel better!
