Hiccups is a problematic condition that has been faced by each one of us at least once in our life. There may not be any person who has never had hiccups. Hiccups may not be a very disturbing condition medically, but it can be a very irritating problem. There are some people who believe that the treatment and remedies for hiccups depend on the cause for the hiccup. There also seems to be no consensus on the cause of the hiccups even in the medical fraternity. What causes hiccups is only a partially answered question with no perfect remedy being followed to decrease the hiccups.
The reason for the lack of a remedy, that is really verifiable, is the fact that the cause itself is not really understood. In spite of this, there are many people who talk about a few causes that can make a person to have hiccups. The most common reason for the hiccup that many people agree upon is the stretching of the diaphragm. This diaphragm is a muscular tissue that is present in the body and divides the respiratory organs and the stomach region. This is a flat muscular tissue and is supplied by the phrenic nerve. In case of any problems to the phrenic nerve, the nerve supply to the diaphragm is affected and this can be a major cause of the hiccups.
In fact the main cause of the hiccups is the spasm of the diaphragm. This is caused by the phrenic nerve when it is damaged. Each spasm of the diaphragm causes a hiccup. This spasm causes an uncontrolled contraction of the diaphragm muscle leading to a sudden intake of air by the person and this causes the actual hiccup.
Hiccups have been found to have been caused in many other conditions too, though the correlation between these causes and the diaphragm contraction or spasm is not known. Drinking heavily is found to cause hiccups in some people. In some other people any rapid intake of breath can also cause hiccups. A person may take in a breath suddenly when they sneeze or even cough and this can be a trigger for hiccups to occur.
In some people, eating spicy food can also be a trigger for the hiccup to occur. In many people, there may not even be an identifiable cause of the hiccup. Though the hiccups are not a medical condition, it does not seem to cause any damage to the body. It is also not really something that causes benefit to the body.
