Sleep Apnea Without CPAP: What to Know

Obstructive sleep apnea (OSA) is far more than just loud snoring. It’s a common sleep disorder in which the airway repeatedly collapses or becomes blocked during sleep, causing pauses in breathing throughout the night. These interruptions can happen dozens—or even hundreds—of times, often without the person realizing it. While it may seem like a nighttime inconvenience, untreated obstructive sleep apnea can have serious short- and long-term health consequences

The Risks of Untreated Obstructive Sleep Apnea (OSA)

When OSA goes untreated, the body is exposed to repeated drops in oxygen levels and frequent sleep disruptions. Over time, this can significantly increase the risk of

  • High blood pressure
  • Heart attacks
  • Stroke
  • Abnormal heart rhythms

Beyond physical health, untreated sleep apnea can take a toll on daily life. Chronic fatigue, poor concentration, memory issues, irritability, and mood changes are common. Many people with untreated OSA struggle with daytime sleepiness, which raises the risk of workplace accidents and motor vehicle crashes. In short, untreated OSA not only affects how long you live, but also how well you live.

When Standard Therapy Isn’t Tolerated

Continuous positive airway pressure (CPAP) therapy is the gold standard treatment for obstructive sleep apnea. When used consistently, it is highly effective at keeping the airway open during sleep. However, CPAP isn’t easy for everyone. Studies show that a significant portion of patients—often estimated at 30–50 percent—have difficulty tolerating CPAP long term. Some of the common challenges include mask discomfort, air leaks, claustrophobia, nasal congestion, and interrupted sleep from the device.

Fortunately, there are now options for those struggling with CPAP. Alternative treatments may include:

  • Oral appliance therapy
  • Positional therapy
  • Weight loss strategies
  • Targeted surgery
  • Newer device-based treatments

The key is not to give up on treating sleep apnea altogether, but to find an approach that fits your body, your lifestyle, and your comfort level.

A Newer Option: Hypoglossal Nerve Stimulation with Inspire

For patients with moderate and severe OSA who cannot tolerate CPAP, hypoglossal nerve stimulation offers an innovative alternative. Inspire therapy was the first hypoglossal nerve stimulator implant approved by the FDA in 2014, with now over, 100,000 patients worldwide have been implanted. It is designed to treat obstructive sleep apnea by gently stimulating the hypoglossal nerve, which controls the tongue. By activating this nerve during sleep, the device helps keep the airway open and reduces apnea events.

Inspire works from inside the body and is controlled by the patient with a small handheld remote at bedtime. Many patients appreciate that it doesn’t require a mask or external airflow, making it a more comfortable and natural-feeling option. While it’s not right for everyone, hypoglossal nerve stimulation has become an important solution for patients who have struggled with CPAP therapy and are seeking a long-term, effective way to manage their sleep apnea.

Steven Cox, M.D., is an otolaryngologist with MyMichigan Ear, Nose & Throat. He sees patients of all ages at his office in Midland. Dr. Cox has training in advanced sleep surgery techniques, including the Inspire Hypoglossal nerve stimulator for patients with sleep apnea who can’t tolerate a CPAP machine. “I was very fortunate to train at the University of Tennessee under one of the leading sleep surgeons in the field of ENT,” he said. “In addition, I was very fortunate to have the opportunity to work at St. Jude’s Children’s Hospital, which provided an outstanding foundation for caring for children.”
