Gastric acid reflux may be caused by excessive secretion of gastric acid, dysfunction of cardia sphincter, eating food or drugs that stimulate gastric mucosa, etc. The treatment mainly focuses on inhibiting gastric acid secretion, alleviating gastric acid reflux, and eliminating irritating factors. 1. Excessive secretion of gastric acid: it can be caused by irregular diet and gastrinoma in the stomach. Acid-suppressing drugs such as omeprazole can be given according to the doctor’s prescription for the cause of the disease, and surgery can be given when gastrinoma exists. 2. Cardia sphincter dysfunction: after normal people eat food, food enters the stomach from the esophagus and is restrained by the lower esophagus and cardia sphincter to avoid reflux of gastric contents, but if there is dysfunction of the lower esophagus and cardia sphincter, reflux will occur. The medicines to promote gastrointestinal power, such as domperidone, can be taken as prescribed by the doctor. 3. Dietary and medication factors: some patients eat spicy and stimulating food for a long time, take steroidal anti-inflammatory drugs such as ibuprofen, celecoxib, aspirin, etc., need to adjust the diet, change the medication in time, eliminate the stabbing factors. After the occurrence of acid reflux need to remove the stimulating factors in a timely manner, if the symptoms continue to be unrelieved, you should seek medical attention as soon as possible, under the guidance of a professional physician to clarify the cause of the disease, and to carry out targeted treatment.
