By Mayo Clinic staffSleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. You may have sleep apnea if you snore loudly and you feel tired even after a full night's sleep.
Sleep apnea occurs in two main types: obstructive sleep apnea, the more common form that occurs when throat muscles relax, and central sleep apnea, which occurs when your brain doesn't send proper signals to the muscles that control breathing. Additionally, some people have complex sleep apnea, which is a combination of both.
If you think you might have sleep apnea, see your doctor. Treatment is necessary to avoid heart problems and other complications.
