L-shaped suction-and-swallow drinking straw device cures 92% of hiccups attacks, scientists say

June 22, 2021

From holding your breath, to breathing into a paper bag, there seem to be a plethora of  cures for hiccups—none of which works 100% of the time. Now scientists at the University of Texas Health Science Center at San Antonio say they have found a better solution—a drinking straw device, The Guardian reports.

But what exactly are these strange (and sometimes loud) noises that most of us make—much to our own embarrassment and the amusement of others?

When you get hiccups—or singultus as they are known in medicine –the diaphragm and intercostal muscles suddenly contract. The subsequent abrupt intake of air causes the opening between the vocal folds—known as the glottis— to shut, resulting the socially dreaded “hic” sound.

However, now researchers think they have found a device that will cut hiccups short in over 90% of cases—and do it quickly, according to The Guardian.

Called “the forced inspiratory suction and swallow tool” (FISST), and patented as HiccAway, the $14 plastic device is a rigid L-shaped straw that has a mouthpiece at one end and an adjustable cap with a pressure valve, in the form of a small hole, at the other. Hiccuping people place the device into a glass of water and use it to sip.

The idea is that the enhanced suction required to draw water up through the device requires the phrenic nerve to trigger a contraction of the diaphragm, while the subsequent swallow involves activation of the vagus nerve, among others. As these two nerves are responsible for the hiccups in the first place, the researchers say keeping them busy stops them from causing the unwanted phenomenon.

 “It works instantly and the effect stays for several hours,” Dr Ali Seifi, associate professor at the University of Texas Health Science Center at San Antonio, and a co-author of the study, said.

To evaluate the device. the team analyzed responses from 249 volunteers— more than two-thirds of whom said they had hiccups at least once a month.

Published in the journal JAMA Network Open, the results reveal that the device stopped hiccups in almost 92% of cases. Just over 90% of participants said they found it more convenient than other home remedies, while 183 of 203 participants said it gave better results. The authors say the results held across all demographics, hiccup frequencies and hiccup durations.

However the study has limitations, including that it did not include a control group and was based on self-reported results.

Dr. Rhys Thomas, a consultant neurologist and epilepsy neuroscientist at Newcastle University, who was not involved in the study, said the device was likely to work and was COVID-safe as it did not require input from others.

But he added: “I think this is a solution to a problem that nobody has been asking for,” noting there were other effective and low-cost options, including his own favourite approach of plugging both ears tightly, while drinking a glass of water through a normal straw.

“Anything that allows you to inflate your chest and swallow will work–the key down the back, the ‘boo!’ and the fingers in the ears will do that to a certain degree – and then this [device], if it allows you to have a long, slow swallow, will be a pretty potent way of doing that,” said Thomas, adding another approach was to drink from a glass backwards.

“If you are prepared for the fact you’ll end up wearing some of it, that is my second favorite option,” he said.

Hiccupping actually helps babies to develop

November 14, 2019

Most of us don’t know why we get the hiccups. They arrive as unexpected and annoying interludes in our otherwise orderly days—and we use a variety of questionable (and even silly) methods to get rid of them.

However, now scientists at University College London have discovered that hiccups might play a crucial role in our early development—by helping babies to regulate their breathing, MSN reports.

In a study led by Lorenzo Fabrizi, a specialist in Neuroscience, Physiology, and Pharmacology at the university, researchers who monitored 13 newborn babies found that hiccupping triggered a large wave of brain signals that could aid in their development.

Indeed, Fabrizi said in a statement, this brain activity might help babies “to learn how to monitor the breathing muscles,” eventually leading to an ability to control breathing voluntarily.

He added: “When we are born, the circuits which process body sensations are not fully developed, so the establishment of such networks is a crucial developmental milestone for newborns.”

Since the babies involved in the study were pre-term and full-term, ranging from 30 to 42 weeks gestational age, the scientists believe this development could be typical of the final trimester of pregnancy.

According to the researchers, fetuses and newborn infants often hiccup, MSN reported.

The phenomenon is seen as early as nine weeks into pregnancy, and pre-term infants—those born at least three weeks premature—spend approximately 15 minutes hiccupping every day.

The pre-term and full-term newborns involved in the study had electrodes placed on their scalps and sensors on their torsos to monitor for hiccups.

The researchers found that contractions in the babies’ diaphragms produced three brainwaves, and believe that through the third brainwave babies may be able to link the ‘hic’ sound of the hiccup to the physical contraction they feel.

Kimberley Whitehead, the study’s lead author, told CNN: “The muscle contraction of a hiccup is quite big

Kimberley Whitehead, the study’s lead author, told CNN: “The muscle contraction of a hiccup is quite bigit’s good for the developing brain because it suddenly gives a big boost of input, which helps the brain cells to all link together for representing that particular body part.”

She added that hiccups have no known advantage for adults, and suggested they could be an example of “a hangover from early periods of our life that persists into later life.”

The same researchers have previously theorized that a baby’s kicks in the womb may help it to create a mental map of its own body.

Their new findings may show the same process occurring internally.
