What happens to your body that makes you get the hiccups?

Hiccups are caused by involuntary spasms of the diaphragm, the muscle that separates the chest from the abdomen. When the diaphragm contracts, the vocal cords snap shut, producing the characteristic "hic" sound.

There are many different things that can trigger hiccups, including:

* Eating too quickly or drinking too much carbonated飲料

* Sudden changes in temperature

* Stress or excitement

* Smoking or drinking alcohol

* Certain medical conditions, such as gastroesophageal reflux disease (GERD) and hiatal hernia

In most cases, hiccups are harmless and will go away on their own within a few minutes. However, if they persist for more than 48 hours, you should see a doctor.

There are a few different ways to try to stop hiccups, including:

* Holding your breath

* Drinking a glass of cold water

* Eating a spoonful of sugar

* Pulling on your tongue

* Gargling with salt water

* If none of these methods work, you may need to see a doctor for treatment.
