Hi Adecelle, Welcome to HealthcareMagic Forum.
Are you on any kind of Medications or Are you stressed out?. You definitely have Gastritis
but Drug Induced Gastritis has to be ruled out. Kindly get yourself examined by a Physician, since the pain is more after taking food, Duodenal Ulcer
has to be ruled out. You may want to take Antacids and if necessary Antibiotics. Avoid stress and Drink Plenty of water. If you are Overweight
reduce your weight by regular exercises and avoid high calorie foods. Avoid hot spicy foods until the symptoms subside. You should avoid lying down immediately after having food and should go for a Brisk walk before you hit the bed. You may also want keep the head end of your Bed elevated when you sleep. Sleep adequately and eat and Sleep on time. Eat smaller, more frequent meals and drink Alcohol in moderation if at all you drink. Quit smoking
Wish you Good Health.
