Upper airway resistance syndrome (UARS) is when your airway gets partially blocked during sleep, but not to the point of causing a complete absence of breathing (like in sleep apnea). Imagine trying to breathe through a straw that has something blocking it partially. That's what happens in UARS. This makes it harder for air to flow into your lungs, which can cause you to take shallow breaths or snore.
When your airway is partially blocked, your body has to work harder to breathe, which can cause you to wake up multiple times during the night. You may not even realize you are waking up, but this can lead to feeling tired during the day and difficulty concentrating.
UARS can be caused by a variety of factors, such as having a narrow airway, being overweight, or having enlarged tonsils or adenoids. It can also occur in people who have chronic allergies or sinus problems.
If you suspect you have UARS, it is important to see a doctor who can diagnose it and recommend treatment. Treatment may include making lifestyle changes, such as losing weight or avoiding alcohol before bed, or using a device to help keep your airway open during sleep.
Overall, UARS is a condition where your airway gets partially blocked during sleep, which can cause you to wake up frequently and feel tired during the day. But don't worry, there are treatments available to help you breathe easier and sleep better.
