What causes hiccups?

Hiccups occur when your diaphragm—the large muscle that separates your chest from your abdomen—experiences involuntary spasms.

Each spasm is followed by a sudden closure of your vocal cords, which creates the characteristic "hic" sound.

Common triggers for these spasms include:

• Eating too quickly or overeating.
• Consuming carbonated beverages or alcohol.
• Sudden changes in temperature.
• Swallowing air while chewing gum or smoking.
• Emotional stress or excitement.

In most cases, hiccups are harmless and pass on their own after a few minutes. If you experience persistent hiccups that last for more than 48 hours, it is a good idea to consult a doctor, as they can sometimes indicate an underlying health issue.
