Recognising sleep apnoea.

Most people spend a third of their lives sleeping, and thus, sleep has a major impact on all of us. As sleep is a function and not a structure, it is challenging to treat and prevent its complications. Sleep apnoea is one such complication, with serious and potentially life-threatening consequences. Local studies estimate that about 15% of Singapore's population is afflicted with sleep apnoea. The resulting sleep fragmentation may result in poor quality of sleep, leading to daytime sleepiness. Sleep apnoea may also be the underlying cause of high blood pressure, memory loss, poor concentration and work performance, motor vehicle accidents, and marital problems. Evaluation involves a sleep study, followed by patient education, and an individualised step-wise management approach should be explored. Many patients will require follow-up for a long period of time, as management options may not offer a permanent cure; other contributory causes may arise at different phases of their lives, compounded by genetic and hormonal issues, ethnicity and the modern hazards of a fast-paced society.
