Grade A esophagitis is reflux esophagitis La-a, which usually does not resolve spontaneously. Reflux esophagitis La-a is the mildest form of esophagitis, in which the esophageal mucosa forms strips of reddened, eroded areas with a long diameter of less than 5 mm and no fusion lesions. It needs to be cured by taking acid-suppressing drugs and gastric-promoting drugs as prescribed by the doctor, combined with dietary modification. 1. Acid-suppressing drugs: proton pump inhibitors such as omeprazole can inhibit gastric acid secretion to treat inflammation of the digestive tract. 2. Gastric stimulants: such as Itopride hydrochloride can increase the function of the lower esophageal sphincter, promote gastric emptying, and reduce the reflux of gastric contents into the esophagus. 3. Lifestyle adjustment: avoid spicy food, tobacco, alcohol, coffee and other stimulating food, do not lie down immediately after eating, and raise the head of the bed when sleeping. It is recommended that patients with reflux esophagitis grade A should go to regular hospitals in time to improve the relevant examinations and under the guidance of doctors for standardized treatment.
