are central sleep apnea dangerous?

In addition, sudden drops in blood oxygen levels that occur during central sleep apnea may adversely affect heart health. If there's underlying heart disease, these repeated multiple episodes of low blood oxygen (hypoxia or hypoxemia) worsen prognosis and increase the risk of abnormal heart rhythms.

Untreated, sleep apnea can cause high blood pressure and other cardiovascular disease, memory problems, weight gain, impotence, and headaches. Moreover, untreated sleep apnea may be responsible for job impairment and motor vehicle crashes.

Waking very early in the morning can also be a sign of sleep apnea. Episodes of apnea—the temporary interruptions to breathing that's the hallmark of the disorder—can occur in every stage of sleep.

It can be mild, moderate, or severe, depending on the number of times in an hour that your breathing stops (apnea) or becomes very shallow (hypopnea). Apnea episodes may occur from 5 to 100 times an hour. More than five apneas per hour is abnormal. More than 30-40 per hour is considered severe sleep apnea.

Snoring is also considered bad because it can disrupt your sleep and lead to many uncomfortable complications, including daytime sleepiness, concentration problems, and an increased likelihood of car accidents. In short, chronic loud snoring isn't just annoying—it can also be dangerous and deserves medical attention.

As with most medical conditions linked to sleep apnea, the connection between stress and sleep apnea is mostly indirect, and it varies from person to person. For instance, post-traumatic stress disorder (PTSD) has been linked to sleep apnea.

These breathing pauses can prevent your body from supplying enough oxygen to the brain. In severe cases this lack of oxygen can lead to brain damage. Signs of this damage include memory problems, difficulty concentrating, and moodiness. The new study involved 17 men with severe, untreated sleep apnea.

Obstructive sleep apnea might also increase your risk of recurrent heart attack, stroke and abnormal heartbeats, such as atrial fibrillation. If you have heart disease, multiple episodes of low blood oxygen (hypoxia or hypoxemia) can lead to sudden death from an irregular heartbeat. Type 2 diabetes.

These outcomes can include postoperative confusion, heart attack, pneumonia and stroke. Some specific conditions increase the risk to the patient undergoing general anesthetic, such as: obstructive sleep apnea, a condition where individuals stop breathing while asleep. seizures.

In adults, the most common cause of obstructive sleep apnea is excess weight and obesity, which is associated with soft tissue of the mouth and throat. During sleep, when throat and tongue muscles are more relaxed, this soft tissue can cause the airway to become blocked.

Researchers found that sleep-disordered breathing leads to a buildup of brain beta-amyloid, a key marker for Alzheimer's disease. New studies released at the Alzheimer's Association International Conference in London this week show more evidence that sleep apnea contributes to a greater risk of dementia.

Mild Sleep Apnea May Raise Heart Risk 24, 2008 -- Sleep apnea -- even if it is so mild that people have no daytime drowsiness -- may increase the risk of cardiovascular disease, a study shows.
911633
If left untreated, sleep apnea can increase the risk of health problems, including: High blood pressure. Stroke. Heart failure, irregular heart beats, and heart attacks.

Clinical comorbidities are no more likely in patients with higher apnea indices than hypopnea indices. While apneas are considered a more severe form of obstruction, this distinction does not have any known clinically predictive value.

In any case, oxygen is important for the heart. Lack of oxygen, even during sleep puts too much pressure on your cardiovascular system, and eventually it can weaken. Even if you do not currently suffer from any of these conditions, there are still good reasons to treat your sleep apnea and wear your CPAP machine.

Even so, breathing through the mouth all the time, including when you're sleeping, can lead to problems. In children, mouth breathing can cause crooked teeth, facial deformities, or poor growth. In adults, chronic mouth breathing can cause bad breath and gum disease. It can also worsen symptoms of other illnesses.
