A hiccup hits and the hands start moving on instinct.
A paper bag gets crumpled open.
A tongue gets pulled, a breath gets held, a spoonful of sugar gets swallowed dry.
None of it works reliably.
At a medical center in San Antonio, a physician wanted something better than folklore.
So he built a plain plastic straw and asked hundreds of ordinary people to put it to the test.
What makes a hiccup stop, and why most tricks barely touch it
A hiccup starts as a sudden, out of rhythm spasm of the diaphragm, the thin sheet of muscle that separates the chest from the belly and normally handles breathing without a single hitch. When it contracts at the wrong moment, the vocal cords snap shut behind it, and that collision is what makes the telltale sound.
The idea behind the device is that you can interrupt two nerve pathways at once. One is the phrenic nerve, which drives the diaphragm itself. The other is the vagus nerve, engaged when you swallow.
That two nerve explanation is the designers’ proposed mode of action rather than a mechanism proven in a controlled experiment. The inventor says the valve demands a strong vacuum in the chest before any water gets through at all. “This is not a regular straw,” he said. “To drink water through it, you need lots of effort and lots of negative pressure inside your chest.” The forceful pull is meant to engage the diaphragm and the phrenic nerve, while the swallow that follows closes the epiglottis and brings in the vagus nerve, so both are occupied together.
A glass of water and a straw nobody could sip easily
The device looks almost too plain to matter. It is a rigid L shaped tube with a mouthpiece at one end and an adjustable cap at the other, holding a small pressure valve, that the user dips straight into a shallow glass of water. There is no battery, no app and no prescription, just a few inches of molded plastic that launched at roughly 14 dollars a unit and now sells over the counter for around 20.
Seifi has been circling the problem for about two decades. Working as an anesthesiologist, he saw surgery patients in the recovery room develop hiccups, which are far more than a nuisance after an operation.
Home remedies kept coming up short, so he sketched out a valve stiff enough to force real resistance into something as mundane as a sip of water. Because the valve resists the pull, the user has to suck much harder than normal before the first mouthful arrives. The cap has two settings, one for adults and one for children, and the instructions tell people to sip forcefully and swallow immediately, two or three times, expecting relief in one or two attempts.
Hundreds of hiccup sufferers rated it against their own home remedies
To test the idea outside a lab, the team offered the tool worldwide through an online Kickstarter campaign in 2020 and followed users for four months. Of 674 people who volunteered to receive it, 290 consented to take part, and 249 completed the questionnaire and were analyzed.
Most of them knew the problem well. More than two thirds reported hiccups at least once a month, with the typical bout lasting under two hours.
That gave the researchers a pool of people who had already tried the usual tricks and watched most of them fail or fade fast. The results, published as a research letter in JAMA Network Open, were one sided. Users reported that the tool stopped their hiccups in nearly 92 percent of cases, and 226 of the 249, just over 90 percent, answered favorably about how easy it was to use compared with home remedies. No adverse effects were reported.
Where the method still runs into its own limits
This was a cross sectional survey, not a randomized trial with a control group drinking through an ordinary straw, so the comparison rested on each person’s own memory of what tongue pulling or breath holding had felt like. Self reported satisfaction carries real limits, and people who sought the device out through a crowdfunding campaign may rate it more warmly than blinded participants would.
The inventor is also an author and the patent holder, a conflict disclosed in the paper, and the authors themselves call for randomized trials. The underlying anatomy is not in dispute, since the hiccup reflex arc described in medical texts runs through the phrenic and vagus nerves.
A similar interest in what the body does under unusual demands shows up elsewhere, including the case of a Scottish man who went well over a year without food under medical supervision. Folk cures tend to shrink when anyone measures them properly, a theme that echoes work on what the body can be trained to withstand when a single system is pushed past its ordinary range.
A small fix for one of the body’s oldest irritations
None of this means a plastic straw belongs in an emergency room. Hiccups lasting more than 48 hours, or ones that interfere with eating, sleeping or breathing, are a reason to call a doctor rather than reach for a kitchen fix.
The device was tested on the common, fleeting kind that everyone eventually gets. What stands out is how little engineering it took once somebody focused on the two nerves thought to be doing the work.
A problem that had generated paper bags, pulled tongues and dry teaspoons of sugar for generations turned out to have a plausible answer waiting in the geometry of a single valve. So the next time hiccups strike at a dinner table, the fix may not be a dramatic scare or a held breath, just a glass of water and a few seconds of genuinely hard sipping.
