Occult GERD symptoms may present atypically, such as chest pain, epigastric pain, burning sensation in the epigastrium, belching, and some extraesophageal symptoms such as cough, sinusitis, recurrent otitis media, asthma, and dental erosion. There is no typical acid reflux or heartburn, and the onset is more insidious. When you have the above symptoms, you should go to the hospital in time. Doctors can diagnose and screen through a series of tests related to gastroscopy, 24-hour reflux test, proton pump inhibitor test, barium esophagography, esophageal manometry and so on. In daily life, we should pay attention to changing dietary habits, eat less food with high fat content, coffee, strong tea, chocolate, carbonated drinks, etc., and eat more vegetables and fruits, coarse grains, and pay attention to weight control.
