Reflux pharyngitis and reflux esophagitis, the etiology of these two diseases may be the same, generally caused by poor diet, dysfunction of the expansion and clearance of esophageal gastric acid and lower esophageal sphincter abnormality and other factors. 1. Poor diet: some obese patients can cause an increase in abdominal pressure, thus causing reflux of gastric contents. Bad habits such as smoking, alcoholism and high-fat diet can cause increased secretion of gastric acid and lead to the emergence of the disease. 2. Functional abnormality: due to the dysfunction of the expansion and clearance of esophageal gastric acid and gastroduodenal malfunction. When the esophageal emptying is impaired, it will lead to the occurrence of the disease. Abnormal gastric emptying, gastric contents, and duodenal fluid can cause disease. 3. Abnormalities of the lower esophageal sphincter: Abnormalities of the lower esophageal sphincter cause a decrease in the anti-reflux function, leading to reflux of gastric contents, which leads to disease. If the above symptoms occur, it is recommended to go to the hospital in time for early treatment. Conservative treatment, such as the use of proton pump inhibitors (e.g., omeprazole) and gastrointestinal mucosal protectants (e.g., teprenone), can be provided in the gastroenterology department.
