There are many reasons for hiccups, and clinically they are mainly considered to be related to hot and cold stimulation, improper diet, too little activity, mental factors, organic lesions, etc. 1. Hot and cold stimulation: consuming food that is too cold or too hot will stimulate the gastrointestinal tract to have a stress response, causing diaphragm spasm and hiccups; 2. Improper diet: poor diet is the main cause of hiccups, such as eating too much or too fast, drinking Excessive carbonated beverages or alcohol, or excessive consumption of foods that produce gas easily, such as radish, potatoes, sweet potatoes, etc.; 3, too little activity: too little activity can lead to impaired gastric emptying and hiccup symptoms; 4, mental factors: excessive excitement or tension can affect the sympathetic nerves, thus inhibiting gastric peristalsis and emptying function and causing hiccup symptoms in patients; 5, organic factors: mainly consider gastroesophageal reflux disease, Esophageal hiatal hernia and other diseases cause hiccups, followed by sliding esophageal hiatal hernia and relaxation of the cardia sphincter, which can lead to massive reflux of gastric acid and also cause hiccups. In addition, other diseases such as peptic ulcer, chronic gastritis, and gastric cancer can also have hiccups.
