Obesity and Sleep

Definition of Obesity Hypoventilition Syndrome (OHS)

People with significant obesity are at risk for developing Obesity Hypoventilation Syndrome (OHS).  OHS results when the body does not receive enough oxygen and does not eliminate enough carbon dioxide while breathing during sleep.  OHS can cause extreme daytime sleepiness and lead to life threatening medical complications.  OHS is easily treated with an assistive breathing device that is worn during sleep.  Achieving and maintaining a healthy weight can actually eliminate the condition in many people.

Symptoms of OHS

OHS can lead to sleep deprivation.  You may feel excessively tired during the day.  You may fall asleep during the day at unexpected times.  You may feel depressed, moody, and irritable.  You may have a harder time concentrating, performing your usual tasks, solving problems, and remembering things.

OHS can cause morning headaches.

Complications of OHS

Untreated OHS can lead to life-threatening medical complications including high blood pressure, right-sided heart failure, and death.
