Understanding the Risks: High Blood Pressure and Strokes in Untreated Obstructive Sleep Apnea

High Blood Pressure and Strokes in Untreated Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) is a common but serious sleep disorder affecting millions worldwide. Characterized by repeated interruptions in breathing during sleep, OSA can lead to a host of health complications if left untreated. Among the most significant risks associated with untreated OSA are high blood pressure (hypertension) and strokes. At Comprehensive Sleep Care Center, we are dedicated to raising awareness about these risks and providing effective treatment solutions to improve the quality of life for those affected by OSA.

The Link Between OSA and High Blood Pressure

OSA is a condition where the airway becomes blocked during sleep, leading to pauses in breathing and a drop in blood oxygen levels. This triggers a stress response in the body, releasing stress hormones like adrenaline. These hormones increase heart rate and blood pressure. Over time, the constant spikes in blood pressure during sleep can lead to sustained hypertension.

Mechanisms Behind the Risk

  1. Sympathetic Nervous System Activation: The repeated episodes of apnea activate the sympathetic nervous system, causing blood vessels to constrict and heart rate to increase.
  2. Endothelial Dysfunction: The inner lining of blood vessels (endothelium) can be damaged by the fluctuating oxygen levels, impairing their ability to relax and leading to increased vascular resistance.
  3. Increased Inflammation: Chronic intermittent hypoxia (low oxygen levels) can lead to systemic inflammation, contributing to the development and progression of hypertension.

The Connection Between OSA and Stroke

A stroke occurs when the blood supply to part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. OSA significantly increases the risk of both ischemic strokes (caused by blockages) and hemorrhagic strokes (caused by bleeding). This risk is due to several factors linked to untreated OSA:

  1. Increased Blood Pressure: As previously mentioned, hypertension is a major risk factor for stroke. The constant high blood pressure from untreated OSA puts extra strain on blood vessels in the brain.
  2. Atherosclerosis: OSA can accelerate the build-up of plaque in arteries, leading to atherosclerosis, which narrows and hardens the arteries, increasing the risk of blockages.
  3. Blood Clot Formation: The repetitive stopping and starting of breathing can lead to blood clot formation, which can travel to the brain and cause a stroke.

The Importance of Early Diagnosis and Treatment

Early diagnosis and treatment of OSA are crucial in mitigating these risks. Comprehensive Sleep Care Center offers a range of diagnostic and treatment options tailored to each patient’s needs. The most common treatment for OSA is Continuous Positive Airway Pressure (CPAP) therapy, which keeps the airway open during sleep. Other treatment options include lifestyle changes, oral appliance therapy, and in some cases, surgery.

Benefits of Treatment

  1. Reduced Blood Pressure: Effective OSA treatment can lead to a significant reduction in blood pressure, decreasing the risk of hypertension-related complications.
  2. Lower Stroke Risk: By addressing the underlying causes of OSA, the risk of stroke can be significantly reduced.
  3. Improved Overall Health: Treatment of OSA can improve sleep quality, daytime alertness, and overall cardiovascular health.

Untreated obstructive sleep apnea poses serious risks to cardiovascular health, particularly through the development of high blood pressure and increased risk of stroke. At Comprehensive Sleep Care Center, we are committed to providing the highest level of care to diagnose and treat OSA, helping our patients lead healthier, safer lives. If you or a loved one suspects they may have sleep apnea, we encourage you to seek a consultation with our specialists to explore your treatment options.

Sleep Apnea and High Blood Pressure- A Dangerous Pair

Sleep Apnea and High Blood Pressure a Dangerous Pair

Many people think sleep apnea is as simple as loud snoring, but it’s much more than that. Sleep apnea affects many systems in the body and is associated with several serious conditions like high blood pressure.

High blood pressure puts a daily strain on the cardiovascular system which may lead to stroke, heart disease, and other serious conditions. Fortunately, managing high blood pressure with medication and lifestyle changes can reduce your risk for harmful health effects.

It’s important to understand the relationship between sleep apnea and high blood pressure because these two conditions affect one another, and treatment for sleep apnea can lower blood pressure in people who have both.

Sleep Apnea, like high blood pressure, isn’t normally something people usually detect on their own. If you have sleep apnea, you likely don’t know about it unless you’re keeping your bed partner up at night by snoring or that you are gasping in your sleep.

Obstructive sleep apnea occurs when the muscles that support the soft tissues in your throat, such as your tongue and soft palate, temporarily relax. When these muscles relax, your airway is narrowed or closed, and breathing is momentarily cut off. Individuals with sleep apnea stop breathing for short periods of time when sleeping. Pauses in breathing can last just a few seconds to a few minutes and occur as little as 5 to as many as 30 times per hour.

Every time your oxygen level drops, this raises your blood pressure and causes an adrenaline surge. This puts increased stress on your heart because it must work harder to normalize your blood pressure.

 What Is the Relationship Between Sleep Apnea and High Blood Pressure?

 In healthy individuals, blood pressure naturally lowers by between 10 and 20%  at night, a phenomenon that is sometimes referred to as “blood pressure dipping“. People with severe OSA experience blood pressure dips less than 10%, which indicates a “non-dipping” blood pressure pattern.

People who have non-dipping blood pressure at night face an increased risk for cardiovascular issues. Additionally, many patients with OSA experience a sudden and pronounced elevation of their blood pressure when they wake up in the morning. This “morning surge” is another factor that may increase risk for cardiovascular disease.  OSA doesn’t only affect blood pressure at night. Studies show that daytime blood pressure levels also increase with sleep apnea severity.

Sleep apnea is one of the most common sleep disorders in the United States. Of people diagnosed with OSA, it is estimated that around half also have high blood pressure. The good news is that treatment for sleep apnea may aid in lowering blood pressure levels.

If you are suffering from high blood pressure it may benefit you to get checked for sleep apnea. Call one of our sleep medicine professionals today and get on the road to a healthier and happier you!
