What are the causes of gastritis? The most common causes of gastritis are certain medication, H. pylori infection, alcohol drinking, etc.
Causes of Gastritis
The most common causes of gastritis are:
- Long-term use of certain medications such as aspirin, ibuprofen, or naproxen can irritate the stomach lining causing gastritis.
- Drinking too much of alcohol can irritate the stomach lining.
- H. pylori is bacteria, stomach infected by these bacteria can cause stomach lining inflammation.
Relatively, fewer common causes of gastritis are:
- Autoimmune disorders
- Viral infection by cytomegalovirus and herpes simplex virus, mostly affect people with weak immune system.
- Reflex of bile from the small intestine into the stomach (bile reflux).
- Cocaine abuse
- Attempting suicide by eating or drinking corrosive substance can damage the stomach mucosal membrane.
- Too much of stress
- Severe illness
- Major surgery
- Kidney failure
- Those who are placed on a breathing machine
Causes of acute gastritis
Long-term use of NSAIDs and aspirin can inflame your gastric mucosal and causing acute gastritis. Alcohol consumption can increase acid secretion; however, does not cause gastritis.
Causes of chronic gastritis
Autoimmune disorder can destroy the stomach lining, leading to chronic gastritis. Bile secretion aids digestion in the small intestine, in some cases this bile enters through the pyloric valve (when it is removed during surgery or not working properly) causing chronic gastritis. It is also causing by other health conditions such as AIDS, Crohn's disease, certain connective tissue disorders, and liver or kidney failure.
