Breathing Issues During Pregnancy: Causes, Symptoms, and When to Seek Help

For patients in Middleburg, Aldie, Ashburn, Purcellville, Warrenton, Marshall, South Riding, Leesburg, Haymarket, and throughout Loudoun County, pregnancy brings many changes to the body—and for some women, breathing can become more difficult as the second and third trimesters progress.  As the baby grows, weight gain and the baby’s position can place extra pressure on the diaphragm and airway, making it harder to breathe comfortably—especially when lying down or sleeping. At Middleburg Smiles in Middleburg, VA, we believe it is important to talk about these changes because sleep and breathing affect both a mother’s comfort and overall health.

During pregnancy, even women who have never had breathing concerns before may begin to snore or notice signs of sleep-disordered breathing. This can include obstructive sleep apnea, where breathing pauses for 10 seconds or more, or upper airway resistance syndrome, where breathing becomes more restricted and requires extra effort.

Why Breathing Changes During Pregnancy

As pregnancy progresses, the body naturally adapts to support the growing baby. These changes can include:

  • Increased weight
  • Fluid shifts
  • Added pressure in the chest and abdomen

Together, these factors can make breathing feel more difficult—especially at night when lying flat. While symptoms often improve after delivery, they should not be ignored during pregnancy, as reduced oxygen levels can affect both mother and baby.

Possible Effects on Mother and Baby

Sleep-disordered breathing during pregnancy has been linked to several health concerns.

For the mother, potential risks include:

  • Preeclampsia
  • Gestational hypertension
  • Gestational diabetes

For the baby, possible effects may include:

  • Restricted growth
  • Early delivery
  • Low birth weight
  • Increased likelihood of neonatal intensive care
  • Lower Apgar scores at birth

Because of these risks, it is important to discuss any breathing changes with your medical provider.

When to Pay Attention

Some symptoms may seem minor but can signal a larger issue with breathing during sleep. Watch for:

  • Snoring
  • Gasping or pauses in breathing
  • Restless or disrupted sleep
  • Unusual daytime fatigue

If you notice any of these signs, bring them up with your OB-GYN or physician. Early evaluation can help ensure appropriate care.

Supporting Healthier Sleep and Breathing

Not every breathing change during pregnancy indicates a serious condition, but it is always best to take symptoms seriously. Healthy sleep supports overall well-being, and proper oxygen flow is essential for both mother and baby.
