Reflux esophagitis is a lesion of inflammatory damage to the esophageal mucosa caused by reflux of gastric contents, mainly stomach acid. Reflux esophagitis can occur at any age, such as middle-aged and elderly people, as well as people who are obese, smoke, drink alcohol, and have high levels of mental stress, which are at high risk for reflux esophagitis.
