GERD can cause chest pain. GERD is a series of chronic syndromes caused by abnormal reflux of gastric contents into the esophagus, resulting in damage to the esophageal mucosa, with typical clinical manifestations of heartburn and acid reflux, and atypical symptoms including chest pain, belching, foreign body sensation in the throat, painful swallowing, and difficulty swallowing. Generally speaking, people who are obese and in a state of high mental stress and depression for a long time are prone to GERD. The main treatment for GERD is to inhibit gastric acid secretion, promote gastrointestinal peristalsis and accelerate mucosal repair, and commonly used drugs include omeprazole, mosapride and teprenone. Diet and life conditioning are also important, such as maintaining a good mental state, controlling weight, eating less and eating more, and exercising regularly.
