What is Obstructive Sleep Apnoea?

Obstructive Sleep Apnea (OSA) is a sleep disorder characterised by repeated interruptions in breathing during sleep. It occurs when the muscles at the back of the throat relax excessively, leading to a temporary blockage or obstruction of the upper airway. These episodes, known as apneas, can cause a person to partially or completely stop breathing for brief periods. Individuals with OSA often experience disrupted sleep, loud snoring, and may wake up feeling tired despite a full night's rest. In addition to daytime fatigue, OSA can have significant health implications, including increased risks of cardiovascular issues, diabetes, stroke, and cognitive problems, highlighting the importance of timely intervention for improved sleep and overall well-being.

Why Do I Have OSA?

The development of OSA is often linked to various factors, including excessive relaxation of throat muscles during sleep, obesity, enlarged tonsils, and structural abnormalities in the airway. Lifestyle habits such as smoking, alcohol consumption, and sedative use can exacerbate OSA symptoms. Genetic predisposition and age also contribute to the onset of OSA.

How do I know if I have OSA?

Diagnosing OSA typically involves medical professionals, but initial assessments can be made using simple questionnaires like the Epworth Sleepiness Scale and the STOP-BANG questionnaire. These tools help identify common symptoms of sleep-disordered breathing, including snoring and daytime fatigue. Additionally, undergoing a sleep study, either at a sleep center or through home-based monitoring, can provide a comprehensive evaluation of sleep patterns and breathing abnormalities indicative of OSA.

Can anything be done to help manage my OSA?

Management of OSA involves various interventions tailored to individual needs. Lifestyle modifications such as weight loss, smoking cessation, and limiting alcohol consumption can help reduce OSA severity. Continuous Positive Airway Pressure (CPAP) devices are commonly prescribed to maintain airway patency during sleep by delivering pressurised air through a mask worn over the nose or mouth.

For many OSA patients, a snoring appliance can be a useful and effective alternative to a CPAP depending on the severity of their apnoea. These devices offer a comfortable option, particularly for mild to moderate OSA, by repositioning the jaw and tongue during sleep, promoting uninterrupted breathing and improved sleep quality.
