Esophageal ulcers first need to be discontinued from medications that tend to cause esophageal ulcers, and for antibiotics and hormones that cause fungal esophagitis. In addition, treatment should be selected on a case-by-case basis. If the ulcer is large, or if a malignant ulcer is suspected, surgery is needed first. For medication, some drugs that protect the esophageal mucosa and promote the healing of the ulcer need to be used under the guidance of a doctor, along with drugs that promote esophageal peristalsis, and drugs that inhibit stomach acid, including omeprazole, magnesium aluminum carbonate, aluminum phosphate gel, domperidone, etc. If treatment with these drugs is not effective, a biopsy may have to be performed under gastroscopy and, depending on the results of the tissue biopsy, surgical treatment is required if the ulcer is malignant. In addition to medical and surgical treatment, attention needs to be paid to the usual life and diet. Try to avoid spicy and stimulating things, including cold and undigestible things, as well as strong tea and coffee drinks, and also prohibit smoking and alcohol.
