Always burping after total excision of gastric cancer is considered to be related to various factors such as nerve stimulation, mental factors, diet and so on. 1. Nerve stimulation: In the process of total gastric cancer excision surgery, vagus nerve and phrenic nerve are stimulated, which may lead to hiccups after surgery. 2. Mental factors: many patients are in a state of high tension and anxiety after total gastric cancer excision surgery, which may also lead to vagus nerve excitement and hiccups. 3. Diet: after total excision of stomach cancer, patients’ digestion and absorption function is weakened. If they don’t pay attention to diet and like to eat greasy, spicy and stimulating food, it may lead to hiccups. It is recommended to go to gastroenterology department or gastrointestinal surgery department of hospital as soon as possible to clarify the cause of hiccups and take active treatment according to doctor’s instruction.
