Snoring During Pregnancy: A Sign of Sleep Apnea?
Pregnancy is a time of great changes for a woman’s body, and one of the most common complaints during this time is trouble sleeping. With all the physical and hormonal changes happening, it’s no wonder that many pregnant women experience difficulties falling and staying asleep. However, snoring during pregnancy may be more than just a normal part of this phase – it could be a sign of a more serious condition known as sleep apnea.
What is Sleep Apnea?
Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breathing during sleep. These pauses can last from a few seconds to minutes and can occur up to 30 times or more per hour. There are three types of sleep apnea: obstructive, central, and complex sleep apnea syndrome. Obstructive sleep apnea (OSA) is the most common type and occurs when the airway collapses or becomes blocked during sleep. This results in a loud snoring sound as the body struggles to take in air. Central sleep apnea (CSA) is less common and happens when the brain fails to send proper signals to the muscles that control breathing. Complex sleep apnea syndrome (CSAS) is a combination of both OSA and CSA.
How is Sleep Apnea Connected to Pregnancy?
Pregnancy is a known risk factor for sleep apnea, and studies have shown that the prevalence of OSA increases during the second and third trimesters. The exact cause of this connection is not yet fully understood, but it is believed to be due to the many changes that happen to a woman’s body during pregnancy. These changes include weight gain, hormonal fluctuations, and changes in sleeping position.
Weight gain during pregnancy can lead to an increase in body mass index (BMI), which is a known risk factor for OSA. As the body gains weight, there is more pressure on the airway, making it more likely to collapse or become blocked during sleep. Hormonal changes, particularly the increase in progesterone levels, can also contribute to the development of OSA. Progesterone is a respiratory stimulant, and during pregnancy, its levels rise significantly, causing an increase in breathing rate and depth. This can result in shallow breathing or hyperventilation, which can lead to a decrease in oxygen levels and ultimately trigger sleep apnea.

Another factor that may contribute to sleep apnea during pregnancy is changes in sleeping position. As the pregnancy progresses, the growing belly can make it difficult for women to sleep on their stomachs. This often leads to a shift to sleeping on the back, which can worsen sleep apnea. Sleeping on the back increases the risk of airway collapse and can also put pressure on the vena cava, a large vein that carries blood from the lower body to the heart. This can cause a decrease in blood flow and oxygen levels, leading to sleep apnea.
Why is Sleep Apnea During Pregnancy a Concern?
Sleep apnea during pregnancy can have serious consequences for both the mother and the baby. The condition can cause a decrease in oxygen levels, which can put a strain on the mother’s heart and lungs. This can lead to high blood pressure, preeclampsia, and gestational diabetes. There is also evidence that sleep apnea during pregnancy increases the risk of complications during delivery, such as the need for a cesarean section.
For the baby, sleep apnea during pregnancy can result in a decrease in oxygen levels in the womb, which can affect their growth and development. There is also a higher risk of preterm birth and low birth weight in babies born to mothers with sleep apnea.
How to Manage Sleep Apnea During Pregnancy?
If you suspect that you have sleep apnea during pregnancy, it is essential to seek medical advice from your healthcare provider. They may refer you to a sleep specialist who can diagnose and treat the condition. Treatment options for sleep apnea during pregnancy may include lifestyle changes, such as maintaining a healthy weight, avoiding sleeping on your back, and using a pregnancy pillow for support. Your doctor may also recommend using a continuous positive airway pressure (CPAP) machine, which delivers pressurized air through a mask worn over the nose or mouth. In severe cases, surgery may be necessary to correct any structural problems in the airway that contribute to sleep apnea.
In conclusion, while snoring during pregnancy may seem like a common occurrence, it should not be ignored. It could be a sign of a more serious condition such as sleep apnea, which can have adverse effects on both the mother and the baby. Seeking medical advice and proper treatment can help manage sleep apnea during pregnancy and ensure a healthy and restful pregnancy for both mom and baby.
