What causes excessive stomach acid?
I have been feeling uncomfortable in my stomach for the past two days, with nausea and a feeling of disgust in my abdomen. I also have a sour taste in my mouth. I would like to know what causes excessive stomach acid.

3. Medication factors: certain medications, such as aspirin and indomethacin, can irritate or damage the gastric mucosa, leading to dysregulation of gastric acid secretion.
4. Psychological factors: when experiencing mental stress, excessive fatigue, or negative emotions, dysfunction of the cerebral cortex may occur, impairing the regulation of gastric acid secretion via the nervous system, thus leading to increased acid production.
5. Disease-related factors: endocrine disorders such as gastrinoma and hyperplasia of gastric antrum G cells can cause abnormal increases in gastric acid secretion.
Patients are advised to adjust their diet, avoid irritant foods, maintain healthy lifestyle habits, and, when necessary, use anti-acid medications under the guidance of a physician.
