Why do we get hiccups?

                              Why do we get hiccups?

When we hiccup , our diaphragm involuntarily contracts.

What is diaphragm ?

It is the dome shaped muscle that separates the chest cavity from abdomen. It plays an imporatant role in breathing.

The contraction of diaphragm causes the immediate closure of vocal chords, which produces the characteristic sound of hiccup.
However, there is no obvious reason for hiccups. But it is also associated with eating or drinking too fast , being nervous or excited , having irritations in stomach or throat.
