My stomach growls but i feel full, i also have stomach cramps and diarreah sometimes after i eat dairy and my stomach makes weird grumblings, and gas.

See a GI doc: If it especially after eating dairy you may be lactose intolerant. Alternatively you could also have a GI bug. See a gastroenterologist for further workup.

Important: You need a good history and exam and some basic tests to determine the cause. It can be something very simple treated with dietary modification. Or it can be something much more serious like inflammation in the intestine. So please see your pcp
