Acute gastritis facts

Information on Acute gastritis

Acute gastritis is an umbrella terms which is used for a wide variety of entities which are known for causing inflammatory conditions in the gastric mucosa. These entities have unique histologic characteristics even though they share the same general clinical presentation. Gastritis may affect only certain regions of the stomach and in those cases it is referred to as antral gastritis, or it may affect the entire stomach. Acute gastritis may be erosive or nonerosive. Gatric symptoms such as vomiting, nausea and abdominal pain are not related to microscopic inflammations. Most patients who suffer from acute gastritis are asymptomatic and they are diagnosed with this medical condition during endoscopy which usually takes place for some other reasons. The most common symptoms of acute gastritis include abdominal bloating, belching, loss of appetite, vomiting, nausea and nondescript epigastric discomfort. Some cases of acute gastritis may also be accompanied by painful sensations in the abdomen. These cases are usually what are being referred to as phlegmonous gastritis. It is not usual for people who suffer from phlegmonous gastritis to also experience certain other symptoms such as hiccups, chills and sometimes even fever. Acute gastritis is commonly diagnosed by taking biopsy specimens during the process of endoscopy.  Acute gastritis usually affects people who are older than 60, and there are approximately 2 million people in the United States who suffer from this specific type of medical condition.

The imbalance of all the defensive and aggressive factors which are responsible for the integrity of the gastric lining is what can be defined as the common mechanism of injury in all cases of acute gastritis. Reactive gastritis occurs when the person gets exposed to a wide variety of different types of factors or agents. These include ischemia, bile reflux, radiation, stress, cocaine, alcohol and NSAIDs. Erosive gastritis is commonly associated with agents such as naproxen, ibuprofen and other types of NSAIDs. Acute gastritis may also be triggered by different types of viral infections, bacterial infections, tuberculosis, secondary syphilis of the stomach and sometimes even parasitic infections, among other factors. All these causes determine different treatment methods which are supposed to be used.
