What causes hiccups?

Hiccups are caused by a spasm in the diaphragm. The diaphragm is a muscle between your lower ribs and back that helps you breathe. At times, it can contract quickly, forcing a quick exhalation of air from the lungs. As the air rushes past your vocal cords, they contract, causing a distinct “hiccup” sound.

There are a variety of reasons why hiccups may occur. In some cases, the cause is not known. In other cases, hiccups occur because the phrenic nerve (nerve that controls the diaphragm), the diaphragm, or the lungs become irritated. An illness, such as pneumonia, can irritate the phrenic nerve. Hot, spicy, or very cold food or beverages may irritate the diaphragm. Toxic chemicals from smoke or fumes can irritate the lungs. Each of these irritating factors could trigger hiccups.

Some surgeries can cause hiccups, though the exact reason for this is not known. In rare cases, hiccups can result from injury to a specific part of the brain, particularly due to stroke, trauma or a tumor.

What are the risk factors for hiccups?

A number of factors increase the risk of developing hiccups. Not all people with risk factors will get hiccups. Risk factors include:

  • Male gender (males are more likely than females to develop hiccups)
  • Recent surgery
  • Spicy, hot or cold food or drinks
  • Stress, either physical or emotional
