Sleep apnea often goes undiagnosed. Doctors usually can’t detect the condition during routine office visits. Also, no blood test can help diagnose the condition.
Most people who have sleep apnea don’t know they have it because it only occurs during sleep. A family member or bed partner might be the first to notice signs of sleep apnea.
The most common type of sleep apnea is obstructive sleep apnea. In this condition, the airway collapses or becomes blocked during sleep. This causes shallow breathing or breathing pauses.
When you try to breathe, any air that squeezes past the blockage can cause loud snoring. Obstructive sleep apnea is more common in people who are overweight, but it can affect anyone. For example, small children who have enlarged tonsil tissues in their throats may have obstructive sleep apnea.
Central sleep apnea is a less common type of sleep apnea. This disorder occurs if the area of your brain that controls your breathing doesn’t send the correct signals to your breathing muscles. As a result, you’ll make no effort to breathe for brief periods.
Central sleep apnea can affect anyone. However, it’s more common in people who have certain medical conditions or use certain medicines. Central sleep apnea can occur with obstructive sleep apnea or alone. Snoring typically doesn’t happen with central sleep apnea.
