Sleep Apnea

What is Sleep Apnea?

  • During sleep, the back of the throat closes off (obstructs).
  • The difficulty breathing causes brief awakenings or arousal.
  • The awakening allows the airway to open up again.
  • The person falls asleep again, only to have the throat close off again.
  • Obstructions and awakenings may occur hundreds of times during the night.

What are the symptoms of Sleep Apnea?

  • Snoring or snorting at night
  • Choking at night.
  • Perspiration at night.
  • Frequent night-time visits to the bathroom.
  • Morning headaches.
  • Daytime tiredness.
  • Fatigue, poor concentration, irritability.

Are there serious problems associated with Sleep Apnea?

  • The risk of motor vehicle accidents is 4 to 6 times greater.
  • The risk of high blood pressure and heart attacks is approximately twice as high.
  • The risk of strokes is approximately twice as high.
  • Sleep apnea may cause heart failure

What increases the chances of having Sleep Apnea?

  • Sleep apnea runs in families.
  • Alcohol at night may make sleep apnea twice as severe. If you take alcohol, take one drink at least three hours before bedtime.
  • Sedatives may worsen sleep apnea.
  • Some analgesics (pain killers) worsen breathing at night: examples include: codeine (Oxycontin), meperidine (Demerol), morphine (MS Contin), Dilaudid, Talwin.

What is the treatment for Sleep Apnea?

  • If overweight, lose weight.
  • Avoid alcohol and sedatives at night
  • Try to reduce opiod analgesics (pain killers) as far as possible.
  • Don’t drive when sleepy. It can be as dangerous as driving under the influence of alcohol.
  • If sleep apnea is worse when sleeping on the back, sleep on the side using a ‘snore ball’. Sew a sock into the back of your pyjamas, and put a tennis ball in the sock.
  • Oral surgery, dental appliances, and CPAP are therapies for sleep apnea. CPAP is the most reliably effective.
