Sleep Disorders Center

Most Americans are not getting a good night's sleep. Reasons can range from too much caffeine, stress, or a sleep disorder. Although Sleep Apnea is the most common sleep disorder, there are actually 70 sleep disorders including restless leg syndrome, insomnia, narcolepsy and parasomnias like sleep walking or sleep talking. The Hillcrest Hospital South Sleep Disorders Center can help diagnose if you have a sleep disorder so you can get treatment and go back to getting a good night's rest.

What is Sleep Apnea?

Obstructive Sleep Apnea occurs when the muscles of the soft palate and throat relax during sleep, obstructing the airway and making breathing difficult and noisy (snoring). Eventually the airway walls collapse, blocking airflow entirely, which results in a pause in your breathing. Each time breathing stops, your brain sets off a stress reaction, your heart rate increases, your blood pressure increases, your blood sugar increases and your sleep is disturbed. This creates stress on the heart and could result in heart problems and even stroke if left untreated. Sleep Apnea (cessation of breathing) can be a life threatening condition.

Central Sleep Apnea is when the diaphragm does not receive a signal to breathe normally. This also causes your oxygen to drop and your sleep to be disturbed.

Mixed Sleep Apnea occurs as a combination of central and obstructive breathing at the same time.
