Esophagogastric mucosal ectasia, usually not serious, but bleeding, perforation and even cancer may occur in a few patients. Esophagogastric mucosal ectasia refers to the appearance of gastric mucosal epithelium on the normal esophageal mucosa, and this type of change is usually a benign lesion, which usually does not lead to cancer. Most patients do not have obvious clinical symptoms, and some patients may experience symptoms such as heartburn, stomach pain, and bloating. If the patient does not show obvious symptoms, no specific treatment is usually needed. If symptoms occur, proton pump inhibitors such as omeprazole can be used to protect the esophageal mucosa. It should be noted that these drugs may cause nausea and vomiting. Surgery can also be used if medication is not effective. If you suffer from this disease, you don’t need to worry too much, but you should strictly follow your doctor’s instructions and choose the right way to cope or receive reasonable treatment under the guidance of your doctor.
