Q
What causes hiccups?
A
Expert Answer
Hiccups occur when the diaphragm spasms, but triggers vary widely: eating too fast, carbonated drinks, alcohol, temperature changes, or emotional stress. Persistent hiccups can signal underlying conditions. Most remedies lack scientific support—holding breath or breathing into a bag may help by increasing CO2.
