With the increased prevalence of obesity worldwide, the incidence of obstructive sleep apnoea (OSA) has risen substantially. OSA is now also more commonly recognized within the pregnant population. The diagnosis of OSA during pregnancy is logistically difficult for many reasons. The symptoms of an uncomplicated pregnancy are traditionally believed to include sleep disruption and daytime sleepiness, without many specific data differentiating 'normal' from 'pathological', thus complicating the screening process for a true sleep disorder based on symptoms alone. Untreated OSA during pregnancy is associated with a variety of gestational health disorders, along with increased complications during delivery. Although screening protocols and increased healthcare provider awareness have led to earlier diagnosis and treatment of OSA in the general population, their implementation in the pregnant population is lacking. Studies on the use of continuous positive airway pressure in pregnancy have demonstrated its safety, but further research is needed to determine its benefits in this cohort. [ABSTRACT FROM AUTHOR]
