Body problems?

Bare in mind that it is very difficult to determine a certain cause for ulcerative colitis (genetics, environment, etc.)- however, since u brought up how u had an infection in ur gall bladder, im thinking that that could have likely triggered ur colitis; that or a possible autoimmune attack from ur body fighting off the infection. As for ur hearing loss, again this is hard to diagnose, but it could be caused if u indeed had an autoimmune problem with ur infection. Also, if u were on drugs such as diuretics, NSAIDS, aspirin, or some antibiotics, these could cause some damage to ur ears. I know that when i got food poisoning when i was 13 (17 now), i got an autoimmune disease (not really a disease but yeah) and i did lose a little of my hearing and got a few ulcers- but nowadays everything is goin good- so i hope everything works out for you, im sure it will!- TAKE CARE!!!
