Also known as: Singultus
Hiccups are involuntary contractions of the diaphragm followed by sudden closure of the vocal cords, producing the characteristic 'hic' sound. Most resolve within minutes to hours.
Hiccups are extremely common and usually self-limiting, lasting minutes to hours. They result from involuntary diaphragmatic spasms triggered by various irritants.
Persistent hiccups (lasting over 48 hours) and intractable hiccups (lasting over one month) are rare but can indicate underlying conditions affecting the phrenic nerve, vagus nerve, or central nervous system.
Medical causes of prolonged hiccups include GERD, brain lesions, kidney failure, and certain medications. The longest recorded hiccup episode lasted 68 years.
There are several possible reasons you may be experiencing Hiccups. Here are the most common ones.
Eating too much, too quickly, or consuming carbonated drinks stretches the stomach, irritating the diaphragm.
Drinking hot then cold beverages or moving between extreme temperatures can trigger hiccups.
Emotional stimuli affect the vagus and phrenic nerves, triggering diaphragmatic spasms.
Acid irritation of the esophagus near the diaphragm can trigger persistent hiccups.
These approaches may help manage hiccups at home. Always consult a healthcare provider if symptoms persist or worsen.
Hold breath for 10-20 seconds to increase CO2 levels, which can reset the diaphragm.
Sipping cold water slowly stimulates the vagus nerve and may interrupt hiccup reflex.
Bear down as if having a bowel movement to stimulate the vagus nerve.
Usually clinical diagnosis. Persistent cases require imaging, blood tests, and potentially neurological evaluation to identify underlying cause.
See a doctor if hiccups last more than 48 hours, interfere with eating, sleeping, or breathing, or are accompanied by abdominal pain or vomiting.
Steps you can take to reduce the likelihood of experiencing hiccups.
Eat slowly and avoid overeating
Limit carbonated beverages
Avoid sudden temperature changes in food and drink
Hiccups lasting over 48 hours are considered persistent and should be evaluated. Most resolve within minutes to hours.
Rarely. Persistent or intractable hiccups can indicate neurological, gastrointestinal, or metabolic conditions.
No single remedy works for everyone. Breathing techniques (holding breath) and vagus nerve stimulation (cold water, Valsalva) are most commonly effective.
