1, in a bad mood. Being in a bad mood can lead to dysfunction of cerebral cortex, which can't control the nerve of gastric acid secretion well, and then promote the increase of gastric acid secretion, resulting in reflux of gastric acid. Patients can generally be treated with some drugs that nourish nerves, such as mecobalamin and vitamin B.

2. Food stimulation. Food stimulation may also lead to an increase in gastric acid secretion, and then the symptoms of gastric acid reflux appear. At this time, patients can be treated with some acid inhibitors, such as omeprazole and lansoprazole.

3, gastrointestinal diseases. Gastrointestinal diseases may also cause gastric acid reflux. If the patient suffers from chronic gastritis, it may lead to increased gastric acid secretion, insufficient gastric motility and gastric acid reflux, and may be accompanied by clinical manifestations such as belching, nausea, vomiting and abdominal pain. Patients can use some drugs to promote gastric motility under the guidance of doctors, such as domperidone and mosapride, to increase gastric motility and reduce gastric acid reflux.
