Question: I'm a 72 year old female, and have diverticulosis,gastritis, and esophagitis.  I tried to see three different doctors today, but all were booked.  I honestly don't know what to do.  It hurts in my chest, and I can hardly talk.

Gastritis (How is gastritis treated?): Health care providers treat gastritis with medications toreduce the amount of acid in the stomach treat the underlying causereduce the amount of acid in the stomachtreat the underlying causeReduce the Amount of Acid in the StomachThe stomach lining of a person with gastritis may have less protection from acidic digestive juice. Reducing acid can promote healing of the stomach lining. Medications that reduce acid includeantacids, such as Alka-Seltzer, Maalox, Mylanta, Rolaids, and Riopan. Many brands use different combinations of three basic salts—magnesium, aluminum, and calcium—along with hydroxide or bicarbonate ions to neutralize stomach acid. Antacids, however, can have side effects. Magnesium salt can lead to diarrhea, and aluminum salt can cause constipation. Magnesium and aluminum salts are often combined in a single product to balance these effects. Calcium carbonate antacids, such as Tums, Titralac, and Alka-2, can cause constipation. H2 blockers, such as cimetidine (Tagamet HB), famotidine (Pepcid AC), nizatidine (Axid AR), and ranitidine (Zantac 75). H2 blockers decrease acid production. They are available in both over-the-counter and prescription strengths. proton pump inhibitors (PPIs) include omeprazole (Prilosec, Zegerid), lansoprazole (Prevacid), dexlansoprazole (Dexilant), pantoprazole (Protonix), rabeprazole (AcipHex), and esomeprazole (Nexium). PPIs decrease acid production more effectively than H2 blockers. All of these medications are available by prescription.

Curing the infection often cures the gastritis and decreases the chance of developing complications, such as peptic ulcer disease, MALT lymphoma, and gastric cancer. Avoiding the cause of reactive gastritis can provide some people with a cure. For example, if prolonged NSAID use is the cause of the gastritis, a health care provider may advise the patient to stop taking the NSAIDs, reduce the dose, or change pain medications. Health care providers may prescribe medications to prevent or treat stress gastritis in a patient who is critically ill or injured. Medications to protect the stomach lining include sucralfate (Carafate), H2 blockers, and PPIs. Treating the underlying illness or injury most often cures stress gastritis. Health care providers may treat people with pernicious anemia due to autoimmune atrophic gastritis with vitamin B12 injections.Treating H. pylori infection with antibiotics is important, even if a person does not have symptoms from the infection.

Answer: Your doctor will treat gastritis with medications to reduce the amount of acid in the stomach and treat the underlying cause. Reducing acid helps healing the stomach. Medications that reduce acid include antacids, such as Alka-Seltzer, Maalox, Mylanta, Rolaids, and Riopan. H2 blockers, such as cimetidine (Tagamet HB), famotidine (Pepcid AC), nizatidine (Axid AR), and ranitidine (Zantac 75), proton pump inhibitors (PPIs), which  include omeprazole (Prilosec, Zegerid), lansoprazole (Prevacid), dexlansoprazole (Dexilant), pantoprazole (Protonix), rabeprazole (AcipHex), and esomeprazole (Nexium).
