The main reasons for hiccups after drinking are the following: First, chatting and talking while drinking may cause uncoordinated breathing leading to diaphragm spasm, and the main manifestation of diaphragm spasm is hiccups. Secondly, alcohol may react chemically with food, resulting in excessive gas or a series of reactions with bacteria in the stomach and intestines, resulting in gas and hiccups. Thirdly, the temperature of the alcoholic beverage is too low and causes stimulation of the stomach and diaphragm, resulting in hiccups. For these reasons, try to avoid foods that produce gas easily, such as radishes, when you drink and eat. The temperature of the wine should be suitable, not too low, and you should eat first when drinking to avoid direct stimulation of the stomach by alcohol and try to avoid too much gas entering the stomach when drinking.
