Hiccups can be incredibly frustrating. But what exactly happens in your body during an episode?
Medically, hiccups are involuntary, spasmodic contractions of the diaphragm—the muscle separating your chest and abdomen. The signature "hic" sound occurs when your vocal cords snap shut as the epiglottis closes abruptly.
Triggers aren't always pinpointed, but common culprits include aerophagia (swallowing excess air), alcohol consumption, overeating, sudden temperature shifts, and carbonated drinks.
When to Consult a Doctor for Hiccups
Seek medical advice if hiccups last over 48 hours or interfere with eating, sleeping, or breathing. Chronic cases may indicate an underlying health issue.
