Chronic gastritis is non-atrophic, that is, superficial or specific type. The first thing to know about its cause is that it can be caused by Helicobacter pylori, and dietary and environmental factors can also be present. There are also other factors, such as alcoholism or the use of non-steroidal anti-inflammatory drugs. Anyway, for chronic non-atrophic gastritis, usually pay attention in lifestyle, stop smoking and drinking, and review regularly. As long as there are no tumors and no precancerous lesions, there is no major problem. As long as you pay attention to your diet and make adjustments in your lifestyle, there are usually no serious consequences.
