Can gastroenteritis cause gastritis?

Gastritis simply means inflammation of the stomach lining. It can be the result of irritation from bacteria, chemicals, increased stomach acid (from whatever reasons), etc. Many times it's viral. GastroENTERITIS is inflammation of stomach (gastro) and the intestines (enter-). Both terms are not diseases in and of themselves, but rather descriptions of group(s) of syndromes.

So, technically, whatever causes gastroenteritis can also irritate the stomach (gastritis).

Gastritis, Chronic - Chronic gastritis, by definition, is a histopathological entity characterized by chronic inflammation of the stomach mucosa. Gastritis's can be classified based on the underlying etiologic agent (eg, Helicobacter pylori, bile reflux, nonsteroidal anti-inflammatory drugs [NSAIDs], autoimmunity, allergic response) and the histopathological pattern, which may suggest the etiologic agent and clinical course (eg, H pylori;associated multifocal atrophic gastritis). Other classifications are based on the endoscopic appearance of the gastric mucosa (eg, varioliform gastritis). The term gastric refers to your stomach. Gastritis is inflammation of the lining of your stomach, which you may experience as a gnawing or burning pain in your stomach or upper abdomen. Gastritis, which is fairly common, has many causes. The lining of your stomach can become inflamed if you regularly take aspirin or certain other pain relievers that irritate the stomach. Drinking alcohol to excess can damage the lining of your stomach. Another common cause of gastritis is an infection with the same bug that can cause stomach ulcers. Sometimes what's known as stress gastritis develops after traumatic injury or major surgery to the body. Treatment of gastritis depends on the cause, and most causes are easy to diagnose and treat. Antacids or other medications to decrease or neutralize acid in your stomach usually relieve symptoms and promote healing. Most gastritis improves rapidly with treatment. Gastritis is just one of many common digestive problems with somewhat similar signs and symptoms. Gastritis differs from Gastroenteritis, also called stomach flu, gastroenteritis is usually due to a viral infection of the intestines. Signs and symptoms of gastroenteritis often include diarrhea, abdominal cramps, and nausea or vomiting, as well as indigestion. And symptoms typically resolve within a day or two, whereas the discomfort of gastritis may be recurring.
