Crohns disease is a form of inflammatory bowel disease that occurs in the intestines. Living with this untreated is a real bitch, and I had to because doctors couldn't figure out what was wrong with me until they decided to stick a camera up my ass. Symptoms I experienced were intense stomach pain after eating that felt like I was digesting rocks, zero apatite, and constant fatigue that ultimately leads to feeling like shit all the time. It sucks, but once diagnosed and put on treatment it just becomes an annoyance.
Person: Hey, you seem tired and haven't eaten much all day. You okay?
Me: Yeah, It's just Crohns Disease.
