What is Hiccups:
Hiccups happen when a person's intake of air becomes momentarily blocked. It can happen for no apparent reason. It is usually a minor nuisance, but prolonged hiccups can indicate a serious medical problem. When a hiccup forms, it is because of a sudden, involuntary contraction of the diaphragm at the same time as a contraction of the voice box, or larynx, and a total closure of the glottis.
Most cases of hiccups go away on their own without medical treatment. If an underlying medical condition is causing your hiccups, treatment of that illness may eliminate the hiccups. Drugs that may be used to treat long-term hiccups include: Baclofen , Chlorpromazine and Metoclopramide
