Question

what causes hiccups?​

Answer 1

Answer:

Hiccups are caused by involuntary contractions of your diaphragm — the muscle that separates your chest from your abdomen and plays an important role in breathing. This involuntary contraction causes your vocal cords to close very briefly, which produces the characteristic sound of a hiccup.

Answer 2

Answer:

Some causes of hiccups include: Eating too quickly and swallowing air along with foods. Eating too much (fatty or spicy foods, in particular) or drinking too much (carbonated beverages or alcohol) can distend the stomach and cause irritation of the diaphragm, which can cause hiccups.
