Do I even have IBS? I'm not even sure anymore.

the unfortunate thing there is no cure for ibs,my doctor is the same but basically he thinks all girls are having problems in their head,my friend even went to him 3 times for 3 different reasons,he said 'its just in ur head' and all 3 times she ended up in hospital,but he is right on one thing,doctors can cure A,B, and C but ibs is X and they cant cure X,I switched doctors and she told me its just a phrase and i'll grow out of it,or maybe because we suddenly start eating healthy and maybe healthy eating can be a cause too,i'd advice u to go and get all sorts of tests done evn the one where they stick a camra up ur bum,just to make sure,if ibs is confirmed good luck if it hopefully does fade because another cause could just be the hormones
