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 precise 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 identified therapy again then.
The day had come for Sullivan to attempt a contraption he’d invented, a “huge swimming pool pipe hooked up to a blower,” as he describes it. By means of a masks, the system delivered air into the person’s nostril, making a slight improve in strain 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 strain, or CPAP machine. Charges of weight problems, a serious driver of sleep apnea, had simply begun to rise. In in the present day’s weight problems epidemic, practically a billion folks worldwide have sleep apnea.
CPAP machines, Sullivan quickly discovered, have their limits. “Many individuals can’t use them,” he says. “There’s numerous individuality with sleep apnea.” Advances are serving to folks use CPAP extra successfully and offering alternate options. Listed below are essentially the most promising approaches, in response to specialists.
Sleep apnea and CPAP
Though CPAP machines work nicely for tens of tens of millions, many different folks wrestle with them. A few of these challenges could be addressed with the precise 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 Venture Sleep. One drawback for Cooksey, typically skilled by others, was a poorly becoming masks. The machine was handed to her with none directions on troubleshooting consolation points. “Determining tips on how to get snug 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 only, however masks that reach over the mouth can profit those that wrestle with nasal respiratory. Looking out by way of 1000’s of accessible masks could be overwhelming with out assist and supervision from educated respiratory therapists and medical tools corporations. Nonetheless, “entry to those specialists is commonly restricted,” Motz says.

Inside just a few years of beginning CPAP, about 50% of sufferers use it too sometimes or cease fully. Left untreated, sleep apnea contributes to severe well being points together with coronary heart illness, strokes, and diabetes.
Cloud-based platforms and a number of apps assist have interaction folks in utilizing CPAP, and a few telehealth corporations specialise in offering experience nearly to suit folks with the perfect masks. Examples are Lofta and Higher Evening. Equipment could make CPAPs extra usable, comparable to comfortable cushion covers and stands that maintain the CPAP hose above the pinnacle 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 constructions, like a recessed jaw or massive tongue, that make it tougher for CPAP alone to open the airway sufficient, even when the masks suits nicely, Motz says. Much less widespread than obstructive sleep apnea is one other type referred to as central sleep apnea, by which respiratory muscular tissues aren’t energetic sufficient. For these sufferers, CPAP might not assist as a lot.
Getting the precise analysis
One other problem is solely understanding which group you fall into. It’s generally unclear what’s inflicting sleep apnea and even whether or not you’ve got it within the first place. An correct analysis is essential to discovering the precise answer.
One signal of sleep apnea is whether or not you snore. “Loud night breathing is a part of the issue” and must be checked out with docs, says Sullivan, now an emeritus professor of medication on the College of Sydney.
Business sleep trackers in watches and beds can assist detection. Researchers are finding out the reliability of those sensors, but when they supply a sleep apnea alert, observe up along with your physician and a sleep specialist, Motz says. They could suggest a complete sleep examine to search out out extra.

One other kind of examination is a sleep endoscopy, the place a tiny digicam is inserted down the airway to search out particular locations the place it’s obstructed. This could result in extra individualized therapy choices. ENT docs learn about and suggest sleep endoscopies in sure conditions. In any other case, it’s “not generally accessible to folks,” Cooksey says.
New medicines
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 drugs specialist and vice chair of medication for analysis at UC San Diego. “Not for lack of making an attempt, it took me 25 years. However now we’ve got one.”
He’s referring to one of many new GLP-1 weight reduction medicines, referred to as tirzepatide. It helps some folks with sleep apnea, in response to Malhotra’s 2024 examine. Malhotra, who’s additionally a sleep drugs specialist at UC San Diego Well being, thinks the drug works primarily by way of weight reduction, which reduces fats blocking the airway.
His examine centered 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 for those who cease taking this drug, the burden tends to come back again. Plus, it’s costly. “Our objective was to enhance CPAP, not change it,” he says. “These therapies typically 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 yr. It prompts muscular 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 Ladies’s Hospital. One other drug, referred to as atomoxetine, additionally impacts muscular tissues in ways in which might assist, in response to current research.
We don’t know the long-term results of those medicines, Eckert factors out. Sullivan, together with his 50-year window on sleep apnea analysis, remembers progesterone, a steroid that appeared to point out advantages for sleep apnea within the 80s—earlier than it was discovered to lift blood strain.
Life-style
Whereas drug analysis continues, way of life behaviors may also help proper now. For many individuals, decreasing weight by way of train and wholesome vitamin is a strong technique to counter sleep apnea.
“In case your weight goes up, you’re preventing an uphill battle,” Motz says. Dropping 10-15% can scale back sleep apnea severity by about 50%.
Intention for standard train to assist 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 muscular tissues, Eckert says, benefiting sleep apnea. Alternatively, a tool referred to as eXciteOSA can work these muscular tissues by way of electrical stimulation.
Eckert has additionally discovered a hyperlink between wholesome, plant-based diets and 20-30% decrease threat of growing 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 vitality 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 raised perceive remedies for the dysfunction.
Along with vitamin and train, she’s come to understand the significance of sleep hygiene, comparable to getting pure daylight within the morning. The precise sleep place is essential 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. Typically, this implies eradicating or rebuilding tissues of the airway. Twenty years in the past, surgeons had no method 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 digicam), to see precisely how the particular person’s airway is collapsing. “That helps us tailor the surgical therapy to the affected person,” Motz says.
In one other kind 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 mild pulses in a single day that transfer the tongue ahead, opening the airway. The implant may also help significantly, although researchers are working to enhance it.
“We all know surgical procedure isn’t all the time efficient,” Motz says. As a result of it’s invasive, surgical procedure is acceptable just for average or extreme instances; Motz recommends sufferers attempt CPAP and different remedies first. He explores quite a lot of options at his clinic.
Oral gadgets
Many individuals with sleep apnea profit from oral gadgets that pull the decrease jaw ahead and maintain it there, enlarging the opening in the back of the throat. “Oral gadgets could 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 could be difficult. Most dentists have little background on sleep apnea. It’s essential to discover a dentist educated and authorized as an knowledgeable in dental sleep drugs.

Lately, Cooksey labored together with her sleep specialist and a educated dentist to suit a customized oral system. She additionally organized a sleep examine to look at its results, with a lot of the coordination falling on her. Sleep apnea includes 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 together with her daytime vitality. Discovering the precise answer required trial-and-error with myriad methods that work for some, however didn’t pan out for her. “We want as many choices as doable,” she says.
Extra alternate options are on the best way. For instance, Eckert is working to enhance the potassium channel blockers. “Cool improvements are taking place,” he says. “This entire space goes to unfold large open within the subsequent 5-10 years.”
These improvements will possible be mixed with older ones, Sullivan says. “In spite of everything these years, I’ve been anticipating a remedy from surgical procedure or medicine, nevertheless it hasn’t occurred,” he says. “I feel CPAP will preserve a vital function.”
