When a person has OSA their upper airway becomes blocked to the degree that their breathing stops. When the body senses this interruption in oxygen it responds by awakening the person, although he or she may not even know they were briefly awake.
This can happen dozens of times over a night, and this adversely impacts sleep. The airflow is decreased, but not to the degree of OSA. Because it becomes more difficult to breathe, the person will awaken from sleep. He or she may only briefly wake up or they may fully awaken and then have trouble getting back to sleep. If you want to place UARS, it would fall somewhere between snoring which is caused when the airway has some resistance from sagging tissue and OSA.
For the person suffering from UARS, their symptoms are similar to OSA in their daytime fatigue, lack of concentration ability, and the like. Obstructive Sleep Apnea, or OSA, is when someone stops breathing for 10 seconds or more while sleeping.
UARS is usually recognized by the person her or himself. They will notice they wake at 2 or 3 am and keep watching the clock wondering if they ever slept at all. Oral appliances seem to be an effective option, but only case reports and small case series have been reported, and the efficacy of these devices is not yet established for this group of patients. Randomized controlled trials comparing different modalities of treatment with larger numbers of patients and including long-term follow-up are important to better define and establish treatment options in UARS patients.

Similar to OSA, the brain has to arouse itself from deeper stages of sleep to increase respiratory effort. When the brain is constantly being aroused from the deeper stages of sleep, it's not able to perform other important tasks that it needs to complete so that you can feel refreshed in the morning.
This can lead to symptoms of chronic fatigue and excessive daytime sleepiness, which are also present in obstructive sleep apnea. Patients can move from snoring to UARS as a result of aging as muscle tone decreases in the throat and weight gain increase of fatty tissues in the throat, which can increase material resistant to airflow. Women in their third trimester of pregnancy are also more likely to develop UARS as a result of weight gain.
One of the key differences between upper airway resistance syndrome and obstructive sleep apnea is that apneas pauses in breathing and hypopneas decreases in breathing are either absent or very low in patients with UARS. Patients with OSA are often overweight or obese although they can be of normal weight , whereas patients with UARS are often of average weight. Behavior and Lifestyle treatments.
This can include practicing good sleep hygiene , making quality sleep a priority, getting adequate exercise and eating right to avoid weight gain, avoiding alcohol and sedatives before bedtime, and changing sleep position avoiding sleeping on back where gravity aids in creating obstructions. To do this we work closely with other medical providers to determine what therapy is best for you. Do you snore? Are you tired all the time?
Trouble staying awake at work? You may have sleep apnea. Carolinas Dental Sleep Center can help you determine your risk and offer treatment options.
