It is not necessary to be overweight nor snore to suffer from sleep apnea. If you feel tired all the time, with or without the snoring, you may have sleep apnea.

Also, snoring itself can cause sleep deprivation even without apnea. This condition is termed 'Upper Airway Resistance Syndrome'. With UARS, sufferers are constantly awakened because they are struggling to get air through their upper airway, though they never actually stop breathing or have low pulse-ox levels.
