There is no one-size-fits-all way to stop hiccups, but they can be relieved by deep breathing, holding your breath for a while, and, if necessary, using medication such as chlorpromazine.
Hiccups can also occur in healthy people, and are common after eating too fast, overfeeding, consuming hot or cold stimulating beverages, and smoking and drinking alcohol. The hiccups are mainly caused by short-term irritation of the phrenic nerve. It can be relieved by pausing eating, taking a deep breath, and holding the breath temporarily for about 30 to 45 seconds, but this is not a hundred percent effective.
In addition, when there are organic lesions, such as the combination of central nervous system lesions, phrenic nerve damage, etc., the patient may have persistent hiccups, in which case, in addition to the treatment of the primary disease, you can use drugs for the treatment of intractable hiccups, such as chlorpromazine injection.
The above drugs are recommended to be used under the supervision of a doctor.
