Sleep apnoea manifests when breathing repeatedly stops and starts during sleep, often stemming from various causes. These causes include the relaxation of throat muscles, where soft tissues at the back of the throat collapse, obstructing the airway. Additionally, excess weight can contribute to sleep apnoea, as fat deposits around the neck can constrict the air passage. Anatomical factors such as enlarged tonsils, a narrow airway, or a deviated septum can also play a role in the condition. Furthermore, medical conditions can occasionally contribute to sleep apnoea, acting as underlying health issues.
