The presence of burning sensation in the stomach when drinking hot water may also be caused by pathological factors such as gastric ulcer, gastroesophageal reflux and gastrinoma. Patients need to pay attention and go to the hospital in time for gastroscopy and other digestive examinations to clarify the diagnosis before treatment. Common causes and treatment 1, gastric ulcer: mainly to be acid suppression therapy, such as the use of omeprazole and other proton pump inhibitors, but also can be combined with the use of gastric mucosal protective agents to promote ulcer healing; if there is H. pylori infection, but also the eradication of H. pylori, can promote ulcer healing as well as prevent recurrence; for gastric ulcers caused by non-steroidal anti-inflammatory drugs, hormones and other drugs, can be clearly diagnosed after the doctor For gastric ulcers caused by NSAIDs, hormones and other drugs, the need to stop the medication can be determined after the doctor’s diagnosis.

Drugs such as omeprazole and rabeprazole can be applied under the guidance of a doctor to inhibit gastric acid secretion, while aluminum thioglycollate and magnesium aluminum carbonate are applied to protect the gastric mucosa to reduce discomfort; 3. Gastrinoma: It is a gastrointestinal neuroendocrine tumor characterized by high gastric acid secretion and gastric acid stimulation causing damage to the gastric mucosa and causing burning sensation from drinking hot water. Gastrin level check should be improved. After the diagnosis is confirmed, the application of omeprazole and lansoprazole can effectively inhibit gastric acid secretion under the guidance of professional doctors, thus relieving discomfort.
