I'm 17+ I had ulcer years ago, but I was recently diagnosed with gastritis. I weigh 187lbs, my weight is always fluctuating, I was going to the gym for a while but I stopped and added some more weight. I'm a med student, far away from home (I study in ukraine) and it is really difficult to eat healthy. Please I need help :(

You already gave the answer - exercise. Didn't the Doctor who diagnosed the gastritis recommend a specific diet for you?

I know your weight but not your height, so I don't know if you are overweight, grossly overweight - or something else.

Awn am 5'5ft 167cm... the doctor told me to check online... and its is really confusing here.
