Which of the following is NOT a common cause of gastritis?

Excessive hydration is not recognized as a common cause of gastritis. Gastritis is inflammation of the stomach lining and can result from various factors that irritate the gastric mucosa. Bile reflux, heavy smoking, and the use of NSAIDs are all well-documented contributors to this condition.

Chronic bile reflux occurs when bile flows back into the stomach from the small intestine, leading to inflammation and irritation. Heavy smoking can exacerbate mucosal irritation and impair the stomach’s protective mechanisms. Non-steroidal anti-inflammatory drugs (NSAIDs) are known to inhibit the production of protective stomach mucus, making the lining more susceptible to damage and inflammation.

In contrast, excessive hydration does not pose a risk for gastritis, as it does not directly influence the mechanisms that cause gastric mucosal inflammation. Thus, it stands out as the option that does not align with the common causes of this gastrointestinal condition.
