Sleep apnea is a common and potentially devastating sleep disorder that affects nearly 12 million people in the U.S.

Your breathing becomes very shallow, or you may even stop breathing from a few seconds to a few minutes. This can happen 30 times or more an hour.

You may resume normal breathing with a snorting or choking sound. If you have sleep apnea, you may snore loudly, although snoring does not mean you have sleep apnea.

Obstructive sleep apnea, the most common type, is caused by relaxation of soft tissue in the back of the throat that blocks the passage of air. This is also one of the most common conditions our sleep disorder specialists treat at the University of Maryland Sleep Disorders Center.

Sleep Apnea Risk Factors

Risk factors for sleep apnea include age, being overweight, male, having a small airway or a family history of sleep apnea. Children with enlarged tonsils or adenoids are also at risk.

Sleep Apnea Symptoms

You may have sleep apnea if you have one or more symptoms that include:

  • Excessive daytime sleepiness
  • Frequent urination at night
  • High blood pressure
  • Irritability
  • Loss of energy and depression
  • Loud and irregular snoring
  • Moodiness
  • Morning headaches
  • Obesity
  • Poor concentration

Sleep Apnea Effects

People with untreated obstructive sleep apnea are at higher risk for high blood pressure, stroke, heart disease fluid retention, abnormal heartbeats and insomnia.

Because you are not sleeping well, you may be sleepy or tired during the day. This tiredness can affect your concentration, memory and ability to do activities like driving or using heavy machinery safely.

Sleep Apnea Diagnosis

A sleep study can help determine if you have sleep apnea. You spend a night in our sleep lab while a technician monitors and records your sleep patterns.

Sleep Apnea Treatment

Although obstructive sleep apnea can be life-threatening, it is treatable. Depending on your condition, sleep apnea treatment may include:

  • Weight loss if you are overweight
  • Avoiding drugs like sleeping pills, alcohol and sedatives, which can cause sleep apnea
  • Sleeping upright
  • Dental device to wear at night to move your lower jaw down and outward
  • CPAP mask (continuous positive airway pressure), a sleep apnea machine that provides pressurized air to keep your airway open and allow normal sleep
  • Surgery to remove the uvula (the punching bag at the back of your throat) and some soft tissue to enlarge your upper airway
