睡眠呼吸暂停如何影响妊娠
发布日期
由于男性患阻塞性睡眠呼吸暂停的可能性是女性的两倍，这种疾病通常被认为是"男性疾病"。虽然该疾病的大多数危险因素适用于男性，但研究表明越来越多的女性也面临睡眠障碍的风险。事实上，一种完全由女性特有的生理状况往往会导致睡眠呼吸暂停症状——这就是妊娠。
不幸的是，在妊娠期间患睡眠呼吸暂停可能对母亲和婴儿都产生危险的影响。
妊娠为何会引发睡眠呼吸暂停
对于孕妇来说，睡眠呼吸暂停可能由妊娠期间女性体内发生的许多激素变化以及妊娠相关的体重增加引起。随之而来的夜间呼吸暂停会导致缺氧，使女性大脑进入"战斗或逃跑"模式。
母亲的风险
身体随后会释放大量肾上腺素和皮质醇，导致血压升高（可能引发先兆子痫）以及葡萄糖产生增加，增加糖尿病风险。对于妊娠前已经超重且因体重增加而肥胖的女性，风险更高。
婴儿的风险
南佛罗里达大学的一项研究发现，患有睡眠呼吸暂停的母亲所生的新生儿更有可能进入新生儿重症监护室（NICU），最常见的原因是呼吸窘迫。这被认为是因为患睡眠呼吸暂停的母亲剖腹产分娩增加所致。
妊娠期睡眠呼吸暂停会消退吗？
虽然睡眠呼吸暂停症状可能在妊娠期间出现，但在分娩后也可能消退，因为激素恢复平衡，体重减轻。

Yes, in many cases sleep apnea symptoms that develop during pregnancy resolve after delivery. Once hormone levels rebalance and pregnancy weight comes off, the airway typically returns to its pre-pregnancy state. Persistent symptoms after birth should be evaluated by a sleep physician.
Waking up gasping or choking during pregnancy can be a sign of pregnancy-onset obstructive sleep apnea. Hormonal changes and weight gain narrow the upper airway, causing repeated breathing pauses that trigger the brain to wake you up. If this happens regularly, talk to your OB or sleep specialist about a sleep study.
Yes. Untreated sleep apnea in pregnancy is associated with higher rates of preeclampsia, gestational diabetes, C-section delivery, and NICU admissions for the newborn due to respiratory distress. Diagnosis and treatment can significantly reduce these risks.
CPAP is considered safe in pregnancy and is the most common treatment. Sleeping on your side rather than your back also helps, as does keeping pregnancy weight gain within recommended ranges. Always coordinate care between your sleep physician and your OB.
