I recently ended up in ed with gastritis. i was put on somac with success. i'm 35, healthy, modified my diet. could it be food allergy related?

Gastritis: It's virtually impossible to diagnose gastritis without an upper GI endoscopy (scope thru the mouth to examine the esophagus, stomach and upper small intestine). Somac is very effective treatment regardless if the cause might be aspirin, anti-inflammatory medications like Advil (ibuprofen) or Alleve or a bacteria. It's very unlikely that this would be related to a food allergy.
