What is a common cause of gastritis?

A common cause of gastritis is excess alcohol consumption, as alcoholic beverages can irritate the stomach lining and lead to inflammation. This irritation can disrupt the protective barrier of the stomach, making it more susceptible to digestive acids and other irritants, resulting in gastritis. Chronic excessive alcohol intake is particularly notorious for causing changes in the stomach lining that can manifest as this condition.

The other options like high fiber diet, regular exercise, and low sugar intake do not typically contribute to the development of gastritis. In fact, a high fiber diet and regular exercise are generally associated with better digestive health and can help prevent gastrointestinal issues. Low sugar intake also does not correlate with gastritis and can be part of a healthy lifestyle. Therefore, understanding the harmful effects of excess alcohol is crucial in recognizing one of the primary risk factors for gastritis.
