What happen to your diaphragm that causes you hiccup?

Hiccups are involuntary contractions of the diaphragm, the muscle that separates the chest cavity from the abdominal cavity. When the diaphragm contracts, it pulls air into the lungs. The vocal cords then close, producing the characteristic "hic" sound.

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

* Eating or drinking too quickly

* Swallowing air

* Smoking

* Drinking alcohol

* Stress

* Anxiety

* Excitement

* Fatigue

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

Most hiccups go away on their own within a few minutes. However, some people may experience hiccups that last for hours or even days. If your hiccups are severe or persistent, you should see a doctor.

There are a number of things you can do to try to stop hiccups, including:

* Holding your breath

* Drinking a glass of water upside down

* Pulling on your tongue

* Gargling with cold water

* Eating a spoonful of sugar

* Breathing into a paper bag

If these methods don't work, you may need to see a doctor for treatment.
