| There are numerous causes for gastritis
and these are listed below:
1) Medications like ASA and other non-steroidal
anti-inflammatory drugs (NSAIDS) and steroids- this type of
gastritis develops slowly, in otherwise healthy people, presenting
with bleeding or ulcers. Alcohol, caffeine, nicotine can also cause
gastritis.
2) Stress due to severe illness- this is the most
severe type of gastritis. This may occur e.g. after a severe burn
and injuries.
3) Bacterial infection- commonly results from an
infection by Helicobacter pylori ( bacteria that grow in the
mucus secreting cells of the stomach lining). No other bacteria are
known to grow in the normally acidic stomach, but many types of
bacteria may grow if the stomach does not produce acid.
4) Viral or fungal infections- may develop in
people with a prolonged illness or impaired immune
system.
5) Atrophic gastritis- results when antibodies
attack the stomach lining, causing it to become very thin and also
causes destruction of cells that produce acid and enzymes. This
condition usually affects the elderly and those who have had partial
gastrectomy ( a procedure in which part of the stomach is removed).
Atrophic gastritis may cause pernicious anemia because it interferes
with the absorption of vitamin B12 from food.
6) Radiation- causes damage to the stomach lining
and allowing bacteria to invade the stomach wall, causing a sudden,
severe and extremely painful form of gastritis.
7) Unknown causes- Plasma cell gastritis and
