After drinking boiled water that burns the esophagus, the first treatment is to avoid secondary esophageal burns caused by eating hot food again. Subsequent food intake should be soft, preferably liquid, and easily digestible to minimize irritation and burden on the digestive tract. The mucous membrane of the esophagus is made up of squamous epithelial cells, which are a type of renewable cell that can be repaired by the body through metabolism when injury occurs. Meanwhile, you can eat some sesame oil or medical paraffin to lubricate the esophagus, forming an oily protective film on the surface of the esophagus, which can promote the repair of esophageal mucosa. In order to avoid infection caused by burns, you can take Yunnan Baiyao and omeprazole orally, which can promote healing and improve pain.
