Hiccups


Hiccups are a sudden, involuntary squeezing of the main breathing muscle under the lungs. This squeezing action sucks air quickly into the lungs, snapping shut a valve above the voice box. This snapping makes the sound of a hiccup.

Hiccups start suddenly, and usually last for only a few minutes. You might hiccup anywhere between 4 to 60 times a minute. Hiccups will usually stop on their own.

Some known triggers of hiccups include:
Stretching of the stomach after rapid eating etc.
Indigestion
Sudden emotional excitement
Sudden change of air temperature,
Very hot or cold food or drink
Alcohol, or excess smoking

If your hiccups persist for more than 48 hours, they may be due to an underlying problem and you should see the doctor.
