Patients with gastric ulcers do not have fever, and if fever is present, a differential diagnosis is needed to find out if it is accompanied by other symptoms, such as abdominal pain, bloating, lack of gas, bowel movements, and other abdominal symptoms. If abdominal symptoms are accompanied by fever, it is important to exclude the possibility of peptic perforation. If a patient with gastric ulcer simply has a fever, find out if there is a respiratory infection, such as cough, sputum, runny nose, etc. If these conditions are present, it may be a sign of gastric ulcer. If these conditions are present, it may be a respiratory tract infection, which can be appropriately treated with medication. Gastric ulcer patients are not recommended to take antipyretic drugs, especially non-steroidal drugs, may induce gastric ulcer complications.
