As a younger doctor in Sydney, Australia in 1979, Colin Sullivan conceived of an experiment to assist folks with nighttime respiratory points. After a number of months of ready for the appropriate affected person, he met a development employee so drained from disrupted in a single day sleep that he habitually dozed off on the scaffolding.
The person had sleep apnea—his airway was obstructed, which interrupted respiratory at night time, waking him repeatedly. However he refused Sullivan’s suggestion for surgical procedure to create a gap within the neck, the one recognized remedy again then.
The day had come for Sullivan to strive a contraption he’d invented, a “huge swimming pool pipe hooked up to a blower,” as he describes it. By way of a masks, the system delivered air into the person’s nostril, making a slight improve in stress that saved his airway open. He slept peacefully for the primary time in years.
“It was an incredible end result,” Sullivan says. On the time, although, he “by no means imagined” there’d be such a necessity for his steady constructive airway stress, or CPAP machine. Charges of weight problems, a serious driver of sleep apnea, had simply begun to rise. In at the moment’s weight problems epidemic, practically a billion folks worldwide have sleep apnea.
CPAP machines, Sullivan quickly realized, have their limits. “Many individuals can’t use them,” he says. “There’s lots of individuality with sleep apnea.” Advances are serving to folks use CPAP extra successfully and offering options. Listed below are probably the most promising approaches, based on specialists.
Sleep apnea and CPAP
Though CPAP machines work properly for tens of hundreds of thousands, many different folks wrestle with them. A few of these challenges might be addressed with the appropriate steerage and methods.
“I’ve used CPAP for 16 years, and I by no means felt actually well-rested,” says Emma Cooksey, a affected person advocate on the nonprofit Mission Sleep. One downside for Cooksey, usually skilled by others, was a poorly becoming masks. The machine was handed to her with none directions on troubleshooting consolation points. “Determining get comfy with CPAP is a giant lacking a part of the method,” she says.
“It’s not one-size-fits-all,” says Dr. Kevin Motz, an ear-nose-throat (ENT) doctor and sleep apnea researcher at Johns Hopkins. Nostril-only masks are typically simplest, however masks that stretch over the mouth can profit those that wrestle with nasal respiratory. Looking by means of 1000’s of obtainable masks might be overwhelming with out help and supervision from educated respiratory therapists and medical tools firms. Nonetheless, “entry to those specialists is usually restricted,” Motz says.

Inside a couple of years of beginning CPAP, about 50% of sufferers use it too sometimes or cease fully. Left untreated, sleep apnea contributes to critical well being points together with coronary heart illness, strokes, and diabetes.
Cloud-based platforms and a number of apps assist interact folks in utilizing CPAP, and a few telehealth firms focus on offering experience just about to suit folks with the most effective masks. Examples are Lofta and Higher Night time. Equipment could make CPAPs extra usable, similar to cosy cushion covers and stands that maintain the CPAP hose above the top and out of the best way. A chin strap to maintain the mouth closed is one other technique proven to enhance tolerance for CPAP, Motz says.
One other strategy is working with a cognitive behavioral therapist to deal with insomnia signs, claustrophobia, or nervousness posed by CPAP.
Typically airways are obstructed at the least partly because of sure facial and oral buildings, like a recessed jaw or giant tongue, that make it tougher for CPAP alone to open the airway sufficient, even when the masks suits properly, Motz says. Much less widespread than obstructive sleep apnea is one other kind referred to as central sleep apnea, during which respiratory muscle tissues aren’t lively sufficient. For these sufferers, CPAP could not assist as a lot.
Getting the appropriate prognosis
One other problem is just understanding which group you fall into. It’s generally unclear what’s inflicting sleep apnea and even whether or not you might have it within the first place. An correct prognosis is vital to discovering the appropriate answer.
One signal of sleep apnea is whether or not you snore. “Loud night breathing is a part of the issue” and needs to be checked out with docs, says Sullivan, now an emeritus professor of medication on the College of Sydney.
Industrial sleep trackers in watches and beds can help detection. Researchers are finding out the reliability of those sensors, but when they supply a sleep apnea alert, comply with up together with your physician and a sleep specialist, Motz says. They could advocate a complete sleep examine to search out out extra.

One other sort of examination is a sleep endoscopy, the place a tiny digital camera is inserted down the airway to search out particular locations the place it’s obstructed. This will result in extra individualized remedy choices. ENT docs find out about and advocate sleep endoscopies in sure conditions. In any other case, it’s “not generally accessible to folks,” Cooksey says.
New drugs
About 20 years after Sullivan’s CPAP discovery, Dr. Atul Malhotra started his profession as a sleep apnea researcher. “I vowed to search out new remedies,” says Malhotra, a sleep medication specialist and vice chair of medication for analysis at UC San Diego. “Not for lack of attempting, it took me 25 years. However now we now have one.”
He’s referring to one of many new GLP-1 weight reduction drugs, referred to as tirzepatide. It helps some folks with sleep apnea, based on Malhotra’s 2024 examine. Malhotra, who’s additionally a sleep medication specialist at UC San Diego Well being, thinks the drug works primarily by means of weight reduction, which reduces fats blocking the airway.
His examine targeted on folks with weight problems, and it was funded by Eli Lilly, the producer of tirzepatide. Extra analysis is required to know its results. Malhotra provides that if you happen to cease taking this drug, the burden tends to return again. Plus, it’s costly. “Our aim was to enhance CPAP, not change it,” he says. “These therapies usually go hand-in-hand.”

A number of different medicine are being studied. One, a potassium channel antagonist, is taken as a nasal spray and improved apneas in a small trial this 12 months. It prompts muscle tissues that widen the throat to enhance airflow, says the examine’s co-author, Danny Eckert, professor and director of sleep well being at Flinders College and a part-time investigator on the Brigham and Girls’s Hospital. One other drug, referred to as atomoxetine, additionally impacts muscle tissues in ways in which might assist, based on current research.
We don’t know the long-term results of those drugs, Eckert factors out. Sullivan, together with his 50-year window on sleep apnea analysis, recollects progesterone, a steroid that appeared to indicate advantages for sleep apnea within the 80s—earlier than it was discovered to boost blood stress.
Way of life
Whereas drug analysis continues, life-style behaviors can assist proper now. For many individuals, lowering weight by means of train and wholesome vitamin is a robust technique to counter sleep apnea.
“In case your weight goes up, you’re combating an uphill battle,” Motz says. Dropping 10-15% can cut back sleep apnea severity by about 50%.
Purpose for typical train to help weight reduction—or extra focused exercise. Speech pathologists can lead you thru workouts of the throat, referred to as myofunctional remedy, which will improve the endurance of airway muscle tissues, Eckert says, benefiting sleep apnea. Alternatively, a tool referred to as eXciteOSA can work these muscle tissues by means of electrical stimulation.
Eckert has additionally discovered a hyperlink between wholesome, plant-based diets and 20-30% decrease danger of creating sleep apnea. Along with warding off the kilos, plant-centric diets decrease irritation all through the physique, one other driver of sleep apnea, Eckert says.
However exhaustion from poor sleep will increase starvation hormones, intensifying meals cravings, Cooksey notes. Sleep apnea drained her power a lot that she left a profession in regulation, choosing much less demanding administrative jobs. 4 years in the past, she began interviewing specialists for a podcast to higher perceive remedies for the dysfunction.
Along with vitamin and train, she’s come to understand the significance of sleep hygiene, similar to getting pure daylight within the morning. The proper sleep place is vital as a result of sleeping in your again can worsen the issue. “Our sleep hygiene must be even higher than the remainder of the inhabitants,” Cooksey says.
Surgical procedure
Surgical procedure is typically another choice. Usually, this implies eradicating or rebuilding tissues of the airway. Twenty years in the past, surgeons had no means of understanding which half to chop, Motz says, however he and others have developed extra exact strategies. Pre-surgery, they carry out a sleep endoscopy (the process involving the digital camera), to see precisely how the particular person’s airway is collapsing. “That helps us tailor the surgical remedy to the affected person,” Motz says.
In one other sort of operation, surgeons implant a tool into the chest that connects to an electrode within the neck, which stimulates a nerve that controls the tongue. Referred to as an Encourage implant, this system sends light pulses in a single day that transfer the tongue ahead, opening the airway. The implant can assist significantly, although researchers are working to enhance it.
“We all know surgical procedure isn’t at all times efficient,” Motz says. As a result of it’s invasive, surgical procedure is acceptable just for average or extreme circumstances; Motz recommends sufferers strive CPAP and different remedies first. He explores quite a lot of options at his clinic.
Oral units
Many individuals with sleep apnea profit from oral units that pull the decrease jaw ahead and maintain it there, enlarging the opening in the back of the throat. “Oral units might be fairly efficient,” generally when mixed with CPAP, Sullivan says.
These aren’t simply run-of-the-mill mouthguards, and getting a dentist to personalize one to your mouth might be difficult. Most dentists have little background on sleep apnea. It’s essential to discover a dentist skilled and licensed as an skilled in dental sleep medication.

Not too long ago, Cooksey labored along with her sleep specialist and a skilled dentist to suit a customized oral system. She additionally organized a sleep examine to look at its results, with many of the coordination falling on her. Sleep apnea entails a number of specialists who “work in silos and don’t speak to one another,” she says.
Different choices on the horizon
After Cooksey mixed CPAP with the oral equipment, her sleep apnea improved alongside along with her daytime power. Discovering the appropriate answer required trial-and-error with myriad methods that work for some, however didn’t pan out for her. “We’d like as many choices as potential,” she says.
Extra options are on the best way. For instance, Eckert is working to enhance the potassium channel blockers. “Cool improvements are occurring,” he says. “This entire space goes to unfold vast open within the subsequent 5-10 years.”
These improvements will probably be mixed with older ones, Sullivan says. “In spite of everything these years, I’ve been anticipating a remedy from surgical procedure or medicine, but it surely hasn’t occurred,” he says. “I feel CPAP will keep an important function.”
