Obstructive Sleep Apnea
Obstructive sleep apnea is the most common form of sleep apnea. Usually with this condition, the airway is blocked, or has collapsed during sleep. This will cause breathing pauses or shallow breathing.
During breathing, the air that tries to flow past this blockage usually causes loud snoring. Obstructive sleep apnea can affect anyone, although it is more common in people who are overweight. In children obstructive sleep apnea is usually caused by enlarged tonsil tissues in their throats.
Central Sleep Apnea
A less common type of sleep apnea is central sleep apnea. This disorder happens if the area of your brain that controls your breathing does not send the right signals to your breathing muscles, and so you stop breathing for short periods of time.
Central sleep apnea can occur in anyone. However, it's more common in people who have certain medical conditions or use certain medicines.
Central sleep apnea often occurs with obstructive sleep apnea, but it can occur alone. Snoring doesn't typically happen with central sleep apnea.
