What Are Hiccups?

A hiccup is a spasm of your diaphragm. This spasm causes an intake of breath that’s suddenly stopped by the quick closing of your vocal cords. The shutting of the vocal cords causes the “hic” sound of a hiccup. “Hiccups are more prevalent in males and in tall people,” says Shane Eikenberry, MD, a primary care doctor at Greater Pittsburgh Medical Associates–UPMC.

What Causes Hiccups?

Hiccups can occur when you have a very full stomach, which can be caused by:

  • Eating too much too quickly
  • Drinking too much alcohol
  • Swallowing too much air (as a result of eating or drinking too fast, chewing gum or sucking on candy, drinking a carbonated beverage, or smoking)
  • A sudden change in stomach temperature — caused by drinking a hot drink and then a cold drink, for example
  • Stress or excitement

Are Hiccups Ever Dangerous?

Hiccups are very rarely dangerous. But if hiccups last longer than 48 hours, they may be a sign of an underlying health issue, such as:

  • A central nervous system problem, like cancer, infections, stroke, or injury
  • A metabolic problem, such as decreased kidney function, or hyperventilation
  • Irritation of the nerves in the head, neck, and chest
  • Mental health problems

How to Treat Hiccups

Hiccups usually go away on their own within a few minutes. But if hiccups are bothering you, you can safely try quickly drinking a glass of cold water or swallowing a teaspoon of honey. Most hiccup home remedies work by increasing the amount of carbon dioxide in your blood.

Treatment of chronic hiccups depends on the underlying cause and ranges from medicine to acupuncture or hypnosis. If you experience chronic hiccups, see your primary care doctor for a diagnosis and treatment.
