Esophagitis is usually referred to as esophagitis, and in the early stage, there will be painful symptoms, mainly manifested as pain when swallowing, which may also be accompanied by dysphagia, acid reflux and other symptoms. Some patients may also experience chronic cough and asthma, which can lead to serious complications. In the early stage, esophagitis does not cause pain, but usually causes pain when swallowing food, such as pain behind the sternum, which may be accompanied by heartburn, acid reflux, dysphagia and other symptoms. Due to the reflux of gastric contents, extra-esophageal manifestations such as chronic cough, asthma and hoarseness may also occur. Prolonged presence of esophagitis may also lead to various complications, such as esophageal ulcers, esophageal stenosis, esophageal obstruction, esophageal hemorrhage and aspiration pneumonia. It is recommended that patients with esophagitis go to the gastroenterology department of the hospital in a timely manner to improve the relevant examinations and actively treat the disease to avoid aggravation of the lesions.
