Avoid going hungry. When the stomach is empty, it increases the acidity level in the stomach. When this happens, the stomach is unable to perform digestion properly as well as enhancing the risk for developing gastritis. Once a person senses high acidity level in the stomach, it will do good to take antacids immediately to neutralize the acidity.
Non-steroidal anti-inflammatory drugs such as pain relievers are known for causing gastritis. When a person cannot stay away from taking pain relievers, other methods for relieving pain should be tried such as using topical remedies. In any case, one should place a limit on the intake of common pain relievers such as aspirin and ibuprofen.
Quit smoking. Smoking interferes with the protective lining of the stomach, thus making the stomach more prone to ulcers and gastritis. Moreover, smoking also increases the amount of acid in the stomach that delays in the healing of gastritis and may even cause cancer of the stomach. If one cannot stop smoking him/herself, it is advised that one consults a doctor for the options available to help one stay away from smoking.
Limit the intake of alcohol. Or a better advice would be to avoid alcohol altogether. This is because alcohol can irritate the mucous lining of the stomach and may cause inflammation and bleeding.
