Risks of Untreated Sleep Apnea
Obstructive sleep apnea (OSA) is more than just snoring or feeling a little tired during the day—it’s a sleep disorder that can seriously impact your health. OSA happens when the airway repeatedly becomes blocked during sleep, causing breathing to stop for a few seconds at a time. This disrupts the sleep cycle and leads to poor quality sleep and oxygen deprivation. While snoring and sleepiness are common symptoms, OSA can have significant long-term health effects if left untreated.
Untreated OSA is associated with a wide range of health risks that can affect almost every system in the body. Here's a look at the main risks of leaving sleep apnea untreated:
The Serious Health Risks of Untreated Sleep Apnea
Heart Disease and High Blood Pressure
OSA can put a lot of strain on the heart and blood vessels. Each time the airway is blocked, oxygen levels drop, causing the body to release stress hormones that raise blood pressure. Over time, high blood pressure (hypertension) can lead to heart problems like heart disease, irregular heartbeats, heart attacks, pulmonary hypertension and even heart failure. People with untreated OSA have a much higher risk of these heart issues compared to those without the condition.
Mental Health and Mood Changes
Poor-quality sleep can take a toll on mental health. People with untreated OSA often experience mood swings, irritability, depression and anxiety. Lack of sleep also impacts focus, memory, and the ability to concentrate, affecting day-to-day tasks and quality of life. Some studies suggest that treating OSA can lead to improvements in mental well-being, with reduced depression and anxiety symptoms.
Fatigue-Related Accidents
One of the most immediate and dangerous effects of untreated OSA is daytime sleepiness. Fatigue from lack of restful sleep can make it hard to stay alert during daily activities, especially when driving. Research shows that people with untreated sleep apnea are much more likely to be involved in car accidents due to drowsy driving. Treating sleep apnea can significantly reduce this risk, making it safer for both patients and those around them.
Weight Gain and Obesity
There’s a close link between sleep apnea and weight gain. When sleep is disrupted, it can interfere with the hormones that control hunger and fullness, making people more likely to overeat. Additionally, fatigue from poor sleep can lower energy levels, making it harder to stay active and exercise regularly. This can create a cycle where weight gain worsens sleep apnea, which in turn leads to more weight gain.
Erectile Dysfunction
Men with untreated sleep apnea are more likely to experience erectile dysfunction. The connection may be due to hormonal imbalances, decreased blood flow, or underlying cardiovascular issues.
Increased Risk of Stroke
When oxygen levels drop during an apnea event, blood flow and pressure fluctuate, stressing the blood vessels in the brain. These changes increase the risk of ischemic stroke, where blood flow to part of the brain is blocked. Studies show that people with untreated OSA have up to a two to four times higher risk of stroke than those who manage their condition.
Type 2 Diabetes and Insulin Resistance
There’s a strong link between OSA and type 2 diabetes. When sleep is constantly interrupted, it can affect the way the body regulates insulin (the hormone that controls blood sugar). This makes people with untreated OSA more likely to have insulin resistance, which increases the risk of developing type 2 diabetes.
Complications During Surgery and Anesthesia
OSA can lead to complications during surgery, especially when anesthesia is involved. Anesthesia relaxes the muscles in the body, including those that help keep the airway open. For someone with untreated sleep apnea, this can increase the risk of breathing problems during and after surgery. It’s essential to let healthcare providers know if you have OSA, as this information helps them manage the airway more carefully during procedures.
Gastroesophageal Reflux Disease (GERD)
OSA can lead to complications during surgery, especially when anesthesia is involved. Anesthesia relaxes the muscles in the body, including those that help keep the airway open. For someone with untreated sleep apnea, this can increase the risk of breathing problems during and after surgery. It’s essential to let healthcare providers know if you have OSA, as this information helps them manage the airway more carefully during procedures.
Morning Headaches
OSA can lead to complications during surgery, especially when anesthesia is involved. Anesthesia relaxes the muscles in the body, including those that help keep the airway open. For someone with untreated sleep apnea, this can increase the risk of breathing problems during and after surgery. It’s essential to let healthcare providers know if you have OSA, as this information helps them manage the airway more carefully during procedures.
How Treating Sleep Apnea Can Make a Difference
There are several effective treatments for OSA that can help reduce these risks and improve quality of life. The most common treatments include:
-
CPAP (Continuous Positive Airway Pressure) Therapy: This involves wearing a mask over your nose or mouth while you sleep. The mask is connected to a machine that delivers a steady flow of air, keeping your airway open so you can breathe continuously. CPAP is highly effective, and many people notice improvements in their sleep quality and daytime energy levels within a few days of starting therapy.
-
Oral Appliances: Some people prefer using a custom-fitted mouthpiece designed to keep the airway open by adjusting the position of the jaw. Oral appliances are less bulky than CPAP machines and can be a good option for people with mild to moderate OSA.
-
Lifestyle Changes: Making lifestyle adjustments can also be helpful. Losing weight, avoiding alcohol (especially before bed), and sleeping on your side can sometimes reduce the severity of OSA. Exercise and healthy sleep habits can improve sleep quality and overall health.
-
Surgical Options: In some cases, doctors may recommend surgery to remove tissue that blocks the airway or reposition parts of the airway. Surgery is typically considered when other treatments aren’t effective or aren’t well-tolerated.
The Benefits of Treating Sleep Apnea
When OSA is treated, most people experience several benefits, including:
-
Better Quality Sleep: Restorative sleep makes it easier to wake up feeling refreshed, stay energized throughout the day, and improve overall well-being.
-
Reduced Risk of Health Complications: Treating OSA helps protect against serious health risks like heart disease, stroke, and diabetes, improving both lifespan and quality of life.
-
Improved Mental Health: With better sleep, people often experience improvements in mood, memory, and concentration. Many report feeling more balanced emotionally and mentally.
-
Lower Accident Risk: Reduced fatigue can make driving and other daily activities much safer, significantly lowering the risk of accidents related to drowsiness.
Taking Action
If you suspect you may have sleep apnea, it’s important to talk to your doctor or a sleep specialist. Simple screening tests and overnight sleep studies can help confirm a diagnosis, allowing you to take steps toward a treatment plan. Treating OSA isn’t just about stopping snoring or preventing tiredness—it’s about protecting your overall health, well-being, and future.
