Well, hiccups are no big problem, but they can embarrass you, especially when you are making a report in front of an entire meeting room. In fact, hiccups are involuntary contractions of the diaphragm, the muscle above your abdomen that helps breathing. The major causes include drinking carbonated beverages, eating too much, excitement or emotional stress.
What are hiccups?
As mentioned earlier, hiccups are contraction of diaphragm, the muscle that seperates your chest from your abdomen and helps breathing. Because each contraction is followed by a sudden closure of your vocal cords, it produces the characteristic "hic" sound. They can happen to people of all age groups, including infants and the elderly.
