The clinical manifestations of patients with esophageal reflux are relatively diverse, with different severity, mainly including the following four:

1. Reflux symptoms are the main symptoms. Heartburn is the most common symptom of esophageal reflux.
2. Food reflux will stimulate the esophagus and cause heartburn, and patients will have retrosternal pain and difficulty swallowing.
3. Irritation symptoms other than the esophagus, such as some sensitive people will have cough, even asthma and throat inflammation. If you feel that cough, asthma, and pharyngitis have nothing to do with the specialist after seeing the respiratory and otolaryngology department, the patient must consider whether there is nocturnal cough, asthma, or pharyngitis caused by esophageal reflux. There are other atypical symptoms that patients have pharyngeal discomfort, a feeling of foreign body in the pharynx and blockage, but there is no obvious difficulty in swallowing.
4. Patients with severe esophagitis will experience complications. The common complications are upper gastrointestinal bleeding, esophageal stricture, and Barrett’s esophagus. Patients need to complete these diagnoses under endoscopy.
