How long can gastritis last?


Most cases of gastritis resolve quickly after treatment begins, according to Mayo Clinic. The National Digestive Diseases Information Clearinghouse explains that untreated gastritis can last for years or even a lifetime.

The National Digestive Diseases Information Clearinghouse explains that gastritis is a condition in which the lining of the stomach is inflamed. Gastritis can be acute, which means that it occurs suddenly, or chronic, which means that it occurs over time. Many people with gastritis do not experience any symptoms, but some may experience nausea, vomiting and upper abdominal discomfort. Most cases of gastritis are caused by Helicobacter pylori, or H. pylori, which is a bacteria that infects the lining of the stomach. This bacteria is commonly transmitted through person to person contact, but it may be transmitted through contaminated food or water in areas with poor sanitation.

Treatment of gastritis is focused on reducing the amount of acid in the stomach to enable the healing of the stomach lining, according to the National Digestive Diseases Information Clearinghouse. Medications, including antacids such as Maalox, histamine 2 receptor blockers such as Zantac and proton pump inhibitors such as Prilosec, are sometimes used to treat the condition. If H. pylori is the cause of gastritis, antibiotics are prescribed to eliminate the bacteria.
