Hiccups and Burps: Causes, Normalcy, and When to Worry

Two Common Reflexes

Hiccups

Involuntary diaphragm spasms → sudden air intake → "hic" sound. Triggers: vagus/phrenic nerve irritation, rapid eating/drinking, carbonation, temperature shifts. Usually brief; >48 hours warrants medical evaluation.

Burping (Eructation)

Release of stomach gas via mouth. Caused by swallowed air (eating/drinking fast, gum), gas-producing foods. Occasional is normal; frequent/excessive may indicate digestive issues—see a doctor.
