Hiccups are caused by an involuntary contraction of the diaphragm — the muscle that separates your chest from your abdomen.
When the diaphragm spasms, the vocal cords snap shut, producing the classic hiccup effect.
Common causes of hiccups include eating or drinking too quickly, swallowing air with food, drinking carbonated or alcoholic beverages, and smoking.
