A couple of weeks ago I realised people would avoid sitting next to me, or slyly cover there nose when they where next to me. I am 17 and studying at college, sometimes I can notice the smell myself but a lot of the time the smell is oblivious to me! I started to notice that ever since I have started to smell like farts/poo that I never seem to fart anymore or rarely do after eating some foods. Also I feel my stomach gas, it's almost like I'm farting on the inside, my poo is very inconsistent for example sometimes I will have constipation but really feel the urge to poo, and other times I will have diareah like poo. Often when I do poo I rarely feel empty I always feel like I could poo more but am unable to do so . Any help and advice would be appreciated thanks.
