Nasal Congestion at 40 Weeks Pregnant

Pregnancy rhinitis — nasal congestion caused by pregnancy hormones rather than a cold or allergy — affects up to 30% of pregnant women. It can start as early as the first trimester and persist until delivery.

👶 What's Happening at Week 40

Your baby is now the size of a small pumpkin.

  • The baby is fully developed and ready for life outside the womb.
  • Lungs are producing enough surfactant for independent breathing.
  • The skull bones are soft and can mold for passage through the birth canal.

🔬 Why You're Experiencing Nasal Congestion at Week 40

  • Estrogen and progesterone cause mucous membrane swelling throughout the body, including nasal passages
  • Increased blood volume causes swelling of nasal blood vessels
  • Not caused by infection or allergens — purely hormonal
  • Pre-existing allergies or colds may worsen alongside pregnancy rhinitis

Frequently Asked Questions

Is it safe to use a decongestant spray during pregnancy?

Oxymetazoline (Afrin) nasal spray is generally considered safe for short-term use (3 days or fewer). Oral decongestants containing pseudoephedrine or phenylephrine are not recommended, especially in the first trimester.

How long does pregnancy rhinitis last?

Pregnancy rhinitis typically lasts throughout pregnancy and resolves within 2 weeks of delivery.

Can nasal congestion during pregnancy cause nosebleeds?

Yes — increased blood volume and sensitive mucous membranes make nosebleeds more common in pregnancy. They are usually harmless.

Can I tell the difference between pregnancy rhinitis and a cold?

Pregnancy rhinitis causes nasal congestion without fever, sore throat, or body aches. A cold typically includes at least one of these additional symptoms.
