Hiccups are involuntary contractions of the diaphragm, the muscle that helps with breathing. When the diaphragm suddenly tightens, it causes a quick intake of air, which makes the vocal cords snap shut, producing the familiar "hic" sound.
Common triggers include eating too fast, drinking carbonated beverages, sudden temperature changes, or even excitement and stress. While occasional hiccups are harmless, persistent ones can indicate an underlying medical condition.
