Hello Dear. You are having chronic gastritis or Acid Peptic Disease (APD). To diagnose gastritis, your doctor will review your personal and family medical history, perform a thorough physical evaluation, and may recommend any of the following tests: • Upper endoscopy. An endoscope, a thin tube containing a tiny camera, is inserted through your mouth and down into your stomach to look at the stomach lining. The doctor will check for inflammationand may perform a biopsy, a procedure in which a tiny sample of tissue is removed and then sent to a laboratory for analysis. • Blood tests. The doctor may perform various blood tests, such as checking your red blood cell count to determine whether you have anemia, which means that you do not have enough red blood cells. He or she can also screen for H. pylori infection and pernicious anemia with blood tests. • Fecal occult blood test (stool test). This test checks for the presence of blood in your stool, a possible sign of gastritis. Treatment for gastritis usually involves: • Taking antacids and other drugs (such as proton pump inhibitors or H-2 blockers) to reduce stomach acid • Avoiding hot and spicy foods • For gastritis caused by H. pyloriinfection, your doctor will prescribe a regimen of several antibiotics plus an acid blocking drug (used for heartburn) • If the gastritis is caused by pernicious anemia, B12 vitamin shots will be given. • Eliminating irritating foods from your diet such as lactose from dairy or gluten from wheat Once the underlying problem disappears, the gastritis usually does, too.
