In healthy people, hiccups are often caused by eating too fast, drinking too much, drinking too much carbonated drinks or alcohol, as well as hot and cold stimuli, excessive excitement or nervousness. Digestive diseases such as reflux esophagitis, intestinal obstruction, cholecystitis, etc., central system diseases such as meningitis, brain tumors, craniocerebral injury, etc., thoracic and pulmonary diseases such as pneumonia, lung cancer, pleurisy, etc.; mediastinal diseases such as pericarditis, acute myocardial infarction, etc., as well as hepatic and renal insufficiency, and surgical stress, etc., may cause hiccups symptoms.
