What Causes Excessive Stomach Acid?
Moderate gastric acid aids digestion; however, excessive gastric acid can damage the mucosa of the stomach and duodenum, leading to peptic ulcers—such as gastric ulcers and duodenal ulcers. Several factors contribute to hyperacidity, including the following: First, excessive mental stress. Prolonged psychological tension disrupts cerebral cortical function, impairing neural regulation of gastric acid secretion—resulting in either excessive or insufficient acid production. Over time, this imbalance adversely affects overall health. Therefore, maintaining a positive mental state at all times is essential to prevent disease.

Second, gastrointestinal disorders. Conditions such as gastritis or cholecystitis may trigger hyperacidity. Third, genetic factors. While abnormal gastric acid secretion is not classified as a hereditary disease, genetic predispositions influence individual constitutional differences, resulting in variable baseline levels of gastric acid secretion. Thus, genetically influenced hyperacidity should not be overlooked.
Fourth, dietary habits. Many people prefer highly stimulating, sweet, spicy, or sour foods—especially strongly flavored or cold dishes (e.g., chilled salads), which are particularly popular in summer. Regular consumption of such foods can irritate and injure the gastric mucosa, stimulating excess acid secretion and causing discomfort. To maintain gastric health, avoid overexertion, sleep deprivation, and intense emotional fluctuations. Consider traveling to relieve daily and occupational stress, thereby promoting psychological stability.
