Mental tension and fear can lead to gastrointestinal dysfunction, and in severe cases, gastric ulcers and gastric bleeding can occur. Factors such as work, life and social pressure can lead to autonomic dysfunction, and nervousness and fear are one of the manifestations of autonomic dysfunction. Autonomic function has a great influence on gastric secretion and motility, and autonomic dysfunction will lead to gastric smooth muscle tension, which will affect the peristaltic function of the stomach and lead to gastrointestinal dysfunction; in addition, when autonomic dysfunction, the secretion of pepsin and gastric acid will increase, which will damage the mucous membrane of the stomach, and thus lead to gastric ulcers and even gastric hemorrhage. Mental tension and fear have a great impact on the stomach’s movement and secretion function, to adjust their own state in time, if necessary, can seek medical help.
