Foods that sooth gastritis symptoms, and that help reduce and stop H. pylori infection growth in the stomach include apples, onions, garlic, teas, green leafy vegetables, coconut water, and wheat bran. Gastritis is diagnosed with endoscopy, blood tests, or stool tests. Some people get relief from gastritis symptoms with prescription and non-prescription antacids, histamine blockers like famotidine (Pepcid AC) or ranitidine (Zantac 75), or proton pump inhibitors (PPIs) like omeprazole (Prilosec) and esomeprazole (Nexium).
