What harm does alcohol consumption cause to the stomach?

Alcohol consumption harms the stomach, particularly when consumed in large quantities. It stimulates gastric acid secretion, leading to symptoms such as vomiting and esophageal injury. Alcohol irritates the gastric mucosa, causing inflammation and potentially resulting in gastritis. Moreover, alcohol not only damages the gastric mucosa but may also lead to hypochlorhydria (reduced gastric acid production). Ethanol—the primary component of alcoholic beverages—can damage the mucosal linings of both the stomach and duodenum, sometimes causing ulceration. Severe cases may result in complications including gastrointestinal bleeding and gastric ulcers; in extreme situations, acute alcohol poisoning may occur. Therefore, it is advisable to minimize alcohol intake in daily life.
