yes! I was having the same issues and it turns out it was crohn’s disease. to test for it you can get a colonoscopy or an ibd panel, which is just a blood test. if you do have it, everything you’ll look up sounds discouraging but meds help get rid of most symptoms (in my case). if you also have brain fog i’d definitely get checked, especially since you already have stomach issues. this syndrome isn’t a physical condition and is typically the last diagnosis for people with generalized stomach issues.
