Sleep Apnea Q & A

What is obstructive sleep apnea?

Obstructive sleep apnea (OSA) is a condition that occurs when you stop breathing while you sleep. When you have OSA, you stop breathing or have an apnea episode 5-30 times every hour.

The soft tissues in your mouth, such as your tongue, relax and fall toward the back of your throat when you sleep. When this happens, they can partially or completely cover the airway, blocking air flow and stopping your breathing.

What symptoms develop due to sleep apnea?

The primary symptoms of sleep apnea include:

  • Loud snoring
  • Fatigue during the day
  • Headache in the morning
  • Difficulty concentrating
  • Waking up with a dry mouth or sore throat
  • Making frequent trips to the bathroom during the night

Loud snoring is the top symptom. Others in your household may notice a repeating cycle: snoring, followed by silence when you stop breathing, then a gasp when you breathe again.

How is sleep apnea diagnosed?

There’s only one way to diagnose sleep apnea and that’s with a sleep study. As a specialist in sleep medicine, Dr. Willoughby offers a home sleep study, which is more comfortable and convenient than going to a sleep lab.

For your home sleep study, Dr. Willoughby supplies the equipment you need and shows you how to use it. Using a few simple pieces — a sensor on your finger, a nasal tube, and an elastic band around your chest — your home sleep study measures your oxygen levels, breathing, and air flow while you sleep.

The information is recorded on a small monitor, then Dr. Willoughby evaluates the data to determine whether you have OSA and the severity of your apnea episodes.

How is sleep apnea treated?

If you have mild sleep apnea and you’re overweight, losing weight may be all you need to stop your apnea. For moderate-to-severe apnea, Dr. Willoughby recommends continuous positive airway pressure (CPAP) or an oral appliance.

When you use CPAP, you wear a mask that delivers enough air to keep your airway open. Although CPAP is the preferred treatment for OSA, some patients with moderate apnea may use an oral appliance. The appliance holds your jaw and tongue in a forward position so your tongue can’t fall over the airway.

If you’re a loud snorer or you’re tired during the day, schedule an appointment online or call Walter J. Willoughby, Jr., MD, for treatment.
