Gastritis is an inflammation of the protective lining of the stomach. Your stomach has a protective lining of mucus called the mucosa. This lining protects your stomach from the strong stomach acid that digests food. When something damages or weakens this protective lining, the mucosa becomes inflamed, causing gastritis. A type of bacteria called Helicobacter pylori is the most common bacterial cause of gastritis.
Acupuncture relieves gastritis and is more effective than the drug ranitidine, an antihistamine. Gastritis causes indigestion with the burning pain of the abdomen, nausea, vomiting, bloating, hiccups, or tarry stools. Acupuncture is more effective than ranitidine for reducing or eliminating gastric mucosal lesions and inflammation in patients with chronic gastritis.
