@tas1950 have you tried supplements like bacteria to repair your intestinal flora, vitamines, glutamine and butyric acid, magnesium bisglycinate, depending on whether you have a histamine intolerance or not. My husband has it, but all of these helped him to repair his intestines and gain weight. After 4 years he still does not feel any hunger or appetite, he does not eat healthy because he simply cannot, he eats a lot of potatoes, which is good in my eyes, but he does not like to eat, because he simply does not know what to eat. This has accompanied him since the surgery, although he was like that before, as well, but now it is even worse, but with the supplements he at least does not have any diarrhea any more, he has fewer dumps, feels better, his mood is better and he gained weight and keeps it. Perhaps this helps. If you want to know, which supplements he is taking, please contact me any time either here. All the best and be patient. Patience you definitely need.
