Danger of Sleep Apnea

Snoring may seem comical, but obstructive sleep apnea is no joke. It can increase your risk of high blood pressure and diabetes — and even make you more dangerous on the road.

Seven health problems linked to obstructive sleep apnea:

High blood pressure
Obstructive sleep apnea can contribute to high blood pressure in people who have it. The frequent nighttime wakings that plague people with sleep apnea cause hormonal systems to go into overdrive, which results in high blood pressure levels at night. Low blood-oxygen levels, caused by the cutoff of oxygen, may also contribute to hypertension in people with sleep apnea.
The good news: Some people with high blood pressure who are treated for sleep apnea can cut back on their blood pressure medications.

Heart disease
People with obstructive sleep apnea are more likely to suffer heart attacks and die in the middle of the night.
The causes may be low oxygen or the stress of waking up often during sleep.
Stroke and atrial fibrillation – a problem with the rhythm of the heartbeat — are also associated with obstructive sleep apnea. The disrupted oxygen flow caused by sleep apnea makes it hard for your brain to regulate the flow of blood in arteries and the brain itself.

Type 2 diabetes
Sleep apnea is very common among people with type 2 diabetes – up to 80% of diabetics have some obstructive sleep apnea.
Obesity is a common risk factor for both disorders. Although studies haven’t shown a clear link between sleep apnea alone and type 2 diabetes, sleep deprivation can cause insulin resistance, a precursor to diabetes. The same lifestyle changes that ease type 2 diabetes symptoms, including diet and weight loss, can improve mild sleep apnea.

Weight gain
Adding weight raises your risk of sleep apnea, and up to two-thirds of people with sleep apnea are severely overweight. Obstructive sleep apnea can often be cured if you lose enough weight.
Being overweight causes fatty deposits in the neck that block breathing at night. In turn, sleep apnea impairs the body’s endocrine systems, causing the release of the hormone ghrelin, which makes you crave carbohydrates and sweets. Also, people with sleep apnea who are tired and sleepy all the time may have lower metabolisms, which can also contribute to weight gain.

Adult asthma
Although the link to
obstructive sleep apnea
is not proven, people who are
treated for sleep apnea
may find they have
fewer asthma attacks.

There’s no proof that
sleep apnea causes acid reflux,
but many people with sleep apnea
complain of acid reflux, and treating
it seems to improve apnea symptoms,
say sleep physicians.

Car accidents
Daytime grogginess can put
people with sleep apnea at
increased risk of falling asleep behind the wheel.
People with sleep apnea are up to
five times more likely than
normal sleepers to have traffic accidents.
