Get really hungry i eat but my stomach is still hungry to the point i need to eat again but i don't. a little while later i'm throwing up. why?

Hunger: You may be misinterpreting reflux, gastritis discomfort for hunger. Eating will appease it to an extent for some, with symtoms only returning. This can also be associated with nausea, pain and vomiting. Try an over the counter medicine like Nexium (esomeprazole) for a few weeks daily to see if this helps. No chance you are pregnant? If symtoms persist or you have bloody vomit, dark stools, see an MD!
