Gastritis (acute)

This condition may present as a gastroenterological emergency with upper gastrointestinal bleeding. It is a temporary stomach lining inflammation caused by stress on the gastric mucosa, manifesting as either haemorrhagic or non-haemorrhagic symptoms. This condition can develop due to various factors, including uraemia, ischemia, shock, corrosive agents, medications, radiation, trauma, severe burns, sepsis, or alkaline-bile reflux.

Certain infections, such as enteroviruses, can also cause a self-limited episode of gastritis. Acute gastritis may result from reduced gastric mucus secretion, mucosal barrier disruption, or decreased mucosal blood flow, depending on the underlying cause
