What is gastritis?

An inflammation, soreness or erosion of the inner lining of the stomach is called gastritis. This inflammation can occur for short term (acute) or long term (chronic). Based on the location and nature of gastritis,




Pangastritis – Gastritis affecting entire stomach



Antral gastritis – Gastritis of a portion of stomach


Erosive gastritis – Over extended exposure to stomach acids, irritation can progress to damage and erosion of inner lining. Based on the extent of erosion, acute gastritis may either be superficial erosive gastritis or deep erosive gastritis.


Hemorrhagic gastritis – In extreme cases, erosion may be accompanied with bleeding and thus called as acute hemorrhagic gastritis.
