Not sure if this is helpful but my husband is dealing with gi issues which seem to have appeared after his covid booster ( he had extreme covid and 2 vaccine boosters). His ability to tolerate and digest various foods has been affected. Great appetite but unable to digest many foods which creates severe bloating, gas and diarrhea so therefore he has had a great weight loss. He is now on pancreatic enzymes since all tests (pet, mri, labs, any scope possible, etc) were unremarkable. The enzymes have helped immensely (Zenpep). For now avoiding caffeine/coffee ( morning tea is ok), oils, fats, fried foods, sugar and red meats has improved his quality of life. He still has triggers that we are trying to identify. Since he is a survivor of skin cancer, head and neck cancer and prostate cancer it is difficult to sort through cause and effect and how much if this is actually a result of covid - though no expert in oncology can attribute it to cancer related issues. It is a journey…. Definitely push for gi testing and from experience have the doctors reevaluate the acid suppressor you are on - changing it or possibly eliminating it. Any additional diagnostic testing like CT or MRI may help tell more of your story. I don’t know how you feel about medical marijuana but there is great data supporting how it alleviates anxiety and may be something to think and discuss with a medical doctor that that field.. Many wishes for a better day today and in the days ahead.

I have the same issues, try eating plant protiens and rice. Sunwarrior is a great plant protien brand, and try to eat some soaked chia seeds. Also sulcrafate can cause some side affects depending on dosage. Pepto bismuth helps a lot when things are terrible for me. Just some things that have helped.
