A hiccup is also called a hiccough which occurs when the diaphragm (the sheet of muscle separating the lungs from the abdomen) suddenly contracts, and the epiglottis (the flap of tissue at the back of the throat that closes the entrance to the voicebox and windpipe during swallowing) closes.

Hiccups are sudden contractions of the muscles we use to breathe in. Just after the muscles start to move, the glottis shuts off the windpipe, producing the characteristic "hic" sound. Hiccups can start in any season it has no any apparent reason and usually disappear after a few minutes. Rarely, hiccups can persist for days, weeks, or months. Hiccups are common and normal in newborns and infants.

Causes of The cause and function of hiccups has baffled medical practitioners since the time of Hippocrates. Although no one has figured out the exact cause science behind these abrupt diaphragmatic contractions. The vagus nerve impulse pattern in the throat causes spasms of the diaphragm which lead to a case of hiccups. By interrupting this pattern many people have success stopping hiccups.

? Eating too fast, especially hot and spicy food;
? Excessive alcohol consumption;
? Smoking; and
? Stress.
