my stomach has been hurting..?

Question

okay so, it seems like every time i eat.. i don't feel well after.
I think there might be something wrong with my digestive system or something? Is there some kinds of foods that can be sensitive on your stomach? Can food get backed up, and cause nausea and stomach pain too? If so, how much food would you have to eat.

Answer 1

Classic signs of gastritis. Here is a pretty comprehensive site on the topic:

You should see a gastroenterologist for proper treatment. The most common treatment includes a regime of proton pump inhibitors.
