Obstructive Sleep Apnea (OSA) Doubles Stroke Risk

Sixteen percent of Americans have obstructive sleep apnea (OSA). A 7-year study included 1,000 patients with OSA and was conducted at the Yale University School of Medicine. The study showed that people with OSA were twice as likely to develop a stroke.

CPAP treatment decreased daytime fatigue, which is a common symptom of OSA, but did not change significantly the stroke risk. The question is what treatment we should use to decrease the risk.

According to the researchers, sleep apnea seems to be an independent risk factor for CAD, HTN and stroke.

Obesity is a known association of OSA and a part of what some Cleveland Clinic doctors call Diabesity - a common combination of DM2 and obesity. Diabesity® is a registered trademark of Shape Up America!©

  1. Causes of sleep apnea are:

    1.An obstructed airway

    2.A central nervous system disorder such as a stroke, a brain tumor, or even a viral brain infection

    3.A chronic respiratory disease

    Effects of Sleep Apnea:

    If left untreated, sleep apnea can result in a growing number of health problems including hypertension, stroke, and heart attacks. In addition, untreated sleep apnea may be responsible for job impairment and motor vehicle crashes as well as academic underachievement in children and adolescents.

    Sleep apnea has serious health consequences and can even be life-threatening. The sleep deprivation that is a result of sleep apnea affects both the sleeper and their bed partn

    The effects of sleep apnea include

    Unclear thinking, lack of concentration

    A compromised immune system and slower healing

    Poor mental and emotional health
    Lack of smooth functioning of the body

    A negative mood, irritability
    Low energy
