What is the reason for the sore mouth?

If there is a sore mouth, it is usually considered a manifestation of gastroesophageal reflux. Because under normal circumstances, the esophagus has an anti-reflux defense mechanism that can prevent gastric contents from flowing back. However, if the esophageal anti-reflux mechanism is reduced for some reason, this will cause gastric contents to flow back into the esophagus or even the mouth. The patient will feel sore mouth. In severe cases, heartburn, chest pain, burning sensation in the upper abdomen, etc. In view of this situation, patients should strictly control their diet, eat more fresh vegetables and fruits, and actively apply relevant drug treatment according to doctor's advice, which can effectively improve this symptom.
