Hiccups are spasms of a muscle in the chest. They repeat without control. Each hiccup feels and sounds like a gasp.

Most hiccups go away quickly. Some may last a few minutes to a few hours. In some people, they may last more than 48 hours. This is not common.


Hiccups are caused by things that irritate a muscle in the chest. This muscle is called the diaphragm. It helps the lungs take in air during breathing.

Risk Factors

Things that may raise the risk are:

  • Eating habits—too much, too fast, or too spicy
  • Drinking alcohol or fizzy drinks like soda
  • Sudden changes in temperature
  • Smoking
  • Stress or strong emotions
  • Certain medical procedures, such as endoscopy

Hard to control hiccups are more common in men. The risk is also higher in people with an underlying health problem or injury.


The main symptom is a repeating spasm in the chest that cannot be controlled. A person may also make a gasping sound.


Medical care may be needed if hiccups do not go away or cause other problems. The doctor will ask about your symptoms and health history. A physical exam may be done. Tests may be done to look for a cause.

Tests may be:


Most hiccups go away on their own. Or they can be treated with methods at home, such as holding one's breath or breathing into a paper bag.

  • Alternative methods, such as massage and acupuncture
  • Medicines such as:
    • Antipsychotics
    • Antiseizure medicine
    • Medicines to treat nausea
