Hiccups are usually caused by overeating. There are many reasons for burping, including functional or organic changes of stomach and esophagus. It is also caused by biochemical and physical stimulation of external substances. For example, too much air enters the stomach and overflows from the mouth, mental and neurological factors (such as vagus nerve excitement and pyloric spasm), bad eating habits (such as eating and drinking too fast), and excessive swallowing (such as too much or too little saliva). However, gastrointestinal neurosis and chronic gastrointestinal diseases cause frequent gastric peristalsis, which is not easy to improve during treatment. Don't worry when burping. If it is caused by overeating and eating too fast, it can be relieved automatically within a few minutes. If it is caused by chronic diseases, it will be fine after spasmolysis and gastric motility treatment. But don't drink cold drinks or do strenuous exercise when you burp. Emergency treatment of hiccups at home: (1) Try to hold your breath and sometimes don't burp. (2) Let burpers drink a small amount of water, especially when burping. (3) When the baby burps, you can pick up the baby and gently scratch the baby's mouth or ears with your fingertips until the baby can stop laughing and burping. (4) If hiccups are difficult to stop, if there is no special discomfort, you can let it be, and it will usually stop in the future. If you burp continuously for a long time, please consult a doctor. Middle-aged and elderly people or patients suddenly burp continuously, which may indicate that there is a disease or the condition is getting worse, so attention should be paid.
