Question

Stress gastritis is characterised by:

• A. Reduction in the blood supply to superficial mucosa of stomach
• B. Disturbance of gastric mucosal barrier
• C. Enterogastric reflux
• D. Autoimmune condition

Hint:

Stress ulcers = mucosal ischemia → shallow erosions → bleeding risk in ICU patients.

Answer 1

The Correct Option is A

Stress gastritis occurs commonly in critically ill patients and is due to mucosal ischemia.
Severe stress, shock, trauma, burns, or sepsis reduce blood flow to the gastric mucosa.
This leads to mucosal damage, erosions, and superficial ulcerations due to lack of oxygen and nutrients.
Although disturbance of the mucosal barrier contributes, the primary mechanism is reduced mucosal blood flow.
It is not related to enterogastric reflux or autoimmune processes.
Therefore, the correct answer is reduction in blood supply to superficial mucosa.
