I have covid gut, actually it was one of my first symptoms when I started this nightmare about 6 months ago,stomach pain,nauseous, abdominal pain ,bloating,massive amounts of gas going up threw my throat I lost 25 pounds I thought I was dieing. I started taking protein powder shakes 2 times a day probioticts, minerals ,vitamin b complex vitamin d, collagen peptides ,eating habits have to change no greasy foods no sugar my stomach is a long way from good but it has gotten better and I put on 12 pounds and have gained some energy back .a good protein powder with collagen peptides was huge for me.
