At The Sleep and Snore Centre, Dr Mark Levi sees many couples anticipating the arrival of a child. While they are filled with joy and excitement, they are also troubled by a lack of sleep due to sleep apnoea. Unfortunately, for many mothers-to-be, pregnancy is accompanied by obstructive sleep apnoea (OSA).
According to the National Sleep Foundation (NSF) in the U.S., 78% of women report more disturbed sleep during pregnancy than at other times. About 15% surveyed by the NSF complained not just of disrupted sleep, but of obstructive sleep apnoea. Considering the physical and emotional demands of pregnancy and the prevalence of sleep disorders among pregnant women, it’s no wonder that expectant mothers get so tired.
Why Sleep Apnoea occurs during pregnancy
Sleep Apnoea is more likely during pregnancy due a combination of factors including hormonal changes and weight gain. High levels of oestrogen during pregnancy can cause the mucus membranes lining the airway to swell, constricting airflow.
People who are overweight or obese are at a significantly higher risk of developing sleep apnoea, therefore the weight gained during pregnancy can also increase the risk. The extra weight on the neck puts pressure on the airway increasing the likelihood of obstructed breathing during sleep. If you gain excessive weight during pregnancy (more than 15 kgs if you were a normal weight before pregnancy, or more than 5 kgs if you were overweight), you’re at an even higher risk. Expectant mothers with gestational diabetes are also at higher risk of having sleep apnoea.
