Finally, a scientific cure for the hiccups

A new device cured the hiccups 92 percent of the time in a recent study involving more than 200 participants.

Finally, a scientific cure for the hiccups

HiccAway

  • Hiccups are an occasional annoyance to most people, but some get them frequently. Others suffer from episodes that last days, months, or even years.
  • A new "suction and swallow" tool stops hiccups 92% of the time by activating the same muscles and nerves that are involved during the hiccup reflex arc.
  • Although the new tool may be convenient, you can probably mimic its function with a glass of water and a straw.

In 1922, an Iowa man named Charles Osborne was preparing to butcher a hog. As he was lifting the 350-pound carcass, he fell. He didn't report any pain to his doctor. But he did walk away with a strange medical condition that earned him a spot in the Guinness Book of World Records: the longest bout of hiccups.

Osborne hiccuped for 68 consecutive years. In total, he hiccuped an estimated 430 million times, at a rate of up to 40 hiccups per minute. He tried numerous home remedies. None worked. Then, one year before his death in 1991, his hiccups mysteriously stopped.

That's an extreme example of a hiccup attack. But even for much shorter episodes, called transient hiccups when they resolve within 48 hours, it can be hard to find a home remedy that works reliably, if you find one at all.

A new remedy recently had its hiccup-quashing abilities put to the test. The "forced inspiratory suction and swallow tool," marketed as the HiccAway, is basically a drinking device with a specialized straw that requires forceful suction to draw liquid.

The idea is to stimulate the same body parts that execute the involuntary hiccup response, so much so that they stop triggering hiccups. (The official medical term is singultus, from the Latin word "singult," which means gasping while sobbing.)

What happens during hiccups?

When you hiccup, your diaphragm — a large, dome-shaped muscle beneath the lungs — involuntarily contracts. This spasm causes the sudden closure of your epiglottis, a flap of cartilage at the root of the tongue that closes when you swallow so that food and liquids don't enter the lungs. The shutting of your epiglottis is what makes the "hic" sound during hiccups.

Two major nerves are involved in the hiccup process. The phrenic nerve helps contract the diaphragm, while the vagus nerve shuts the epiglottis. By forcefully sucking on the tool's straw and then swallowing water, you contract the diaphragm and close the epiglottis. These two actions stimulate the phrenic and vagus nerves, which interrupts the hiccup reflex arc.

The tool has a mouthpiece on the top, a body in the middle, and an adjustable cap with a pressure valve on the lower end.Alvarez et al.

"HiccAway can instantly stop hiccups by generating enough pressure while sipping from the device to lower the diaphragm while simultaneously activating the leaf-shaped flap in the throat, known as the epiglottis," the company writes on its website. "Doing this stimulates two key nerves, the phrenic and the vagus nerves, which are responsible for the hiccups. This allows the brain to reset and stop hiccups."

Testing the device

To test the efficacy of the tool, researchers with the University of Texas Health Science Center at San Antonio sent the HiccAway to more than 600 people who reported having hiccups at least once a month. The results showed that the tool stopped hiccups 92 percent of the time for the 249 participants whose responses were validated in the study. More than 90 percent of participants said it was more effective than home remedies.

"Many home remedies consist of physical maneuvers designed to stimulate contraction of the diaphragm and/or closure of the epiglottis," stated a study published in JAMA Network Open. "These maneuvers lack clear, standardized instructions and can be cumbersome to perform, and there are few, if any, scientific studies of their effectiveness."

Still, it's worth noting that the results were based on self-reported data, and the study didn't feature a control group. Future research could compare the efficacy of HiccAway with a device that looks similar but doesn't function.

It's also worth pointing out that you don't need a $14 device to stimulate the vagus and phrenic nerves. You may just need a glass of water and a straw. A 2006 article published in the British Medical Journal noted that "plugging both ears tightly, pushing both right and left tragus, and drinking the entire glass of water through the straw without pause, without releasing the pressure over the ears" is a "nearly infallible" method to stop hiccups.

What if nothing stops your hiccups? Consider consulting a doctor: Persistent hiccups can signal underlying medical conditions, including pancreatitis, pregnancy, and liver cancer, among others.

    Surprising Science
    • It appears that Earth has a geologic "pulse," with clusters of major events occurring every 27.5 million years.
    • Working with the most accurate dating methods available, the authors of the study constructed a new history of the last 260 million years.
    • Exactly why these cycles occur remains unknown, but there are some interesting theories.

    Ancient Greek military ship found in legendary, submerged Egyptian city

    Long before Alexandria became the center of Egyptian trade, there was Thônis-Heracleion. But then it sank.

    Surprising Science
  • Egypt's Thônis-Heracleion was the thriving center of Egyptian trade before Alexandria — and before earthquakes drove it under the sea.
  • A rich trade and religious center, the city was at its height from the six to the fourth century BCE.
  • As the city's giant temple collapsed into the Mediterranean, it pinned the newly discovered military vessel underwater.

    Which countries are voyaging to Mars this decade?

    We are likely to see the first humans walk on Mars this decade.

    Mars's Twin Peaks

    NASA
    Technology & Innovation
    • Space agencies have successfully sent three spacecraft to Mars this year.
    • The independent missions occurred at around the same time because Earth and Mars were particularly close to each other last summer, providing an opportune time to launch.
    • SpaceX says it hopes to send a crewed mission to Mars by 2026, while the U.S. and China aim to land humans on the planet in the 2030s.
