Nasal Congestion in Pregnancy

Nasal congestion is a surprisingly common pregnancy symptom. Often called pregnancy rhinitis, it causes a blocked or runny nose even when you are not ill. It is driven by hormones and increased blood flow and usually clears after birth.

What Causes Pregnancy Rhinitis

Pregnancy rhinitis can begin at any stage but often becomes more noticeable from the second trimester onwards, when oestrogen levels are at their highest. Unlike a cold, there is no sore throat, fever, or general feeling of being unwell. The congestion tends to be persistent rather than coming and going like hay fever.

Some people also notice that their nose runs more than usual, or that they have unexplained nosebleeds. Both are linked to the increased blood flow and fragility of nasal blood vessels during pregnancy.

Relief and Management

Saline nasal sprays or rinses are the safest first option. They work by flushing out excess mucus and soothing swollen membranes. You can use them as often as needed, and they are completely safe throughout pregnancy.

A humidifier in your bedroom adds moisture to the air and can reduce overnight stuffiness. Even placing a bowl of water near a radiator can help during the colder months.

Sleeping with your head slightly raised — using an extra pillow or raising the head of your mattress — allows gravity to help drain the nasal passages while you sleep.

Staying well hydrated keeps mucus thinner and easier to clear. Aim for plenty of water throughout the day.

Steam inhalation — sitting over a bowl of hot (not boiling) water with a towel over your head — can give temporary relief and is safe to try at home.

Avoid known irritants such as cigarette smoke, strong perfumes, and dusty environments, which can worsen the swelling.

If over-the-counter decongestant sprays are tempting, use caution. Short-term use of some types may be considered on advice from a pharmacist, but using them for more than a few days can cause rebound congestion that makes the problem worse. Always check with your midwife or pharmacist before using any medicated nasal product during pregnancy, including nasal steroids.

When to Seek Help

• You have a high temperature, severe sore throat, earache, or green/yellow discharge from the nose — these suggest an infection rather than rhinitis, and you may need treatment.
• Your congestion is so severe that you are struggling to sleep or eat.
• You are concerned about using any medication and want guidance tailored to your stage of pregnancy.
• You develop significant facial pain or pressure around your sinuses.

Severe, untreated nasal congestion can contribute to snoring and, in some cases, disturbed sleep during pregnancy. If you are very uncomfortable, it is always worth raising it at your next midwife appointment.

Frequently Asked Questions

It often starts in the second or third trimester and resolves within two weeks of birth as hormone levels fall and blood volume returns to normal. Some people have it throughout pregnancy. Unfortunately, unlike morning sickness, it does not usually improve on its own before the baby arrives — but it does clear quickly once you have given birth.

Is a blocked nose a sign of pregnancy?

It can be a symptom, but it is not specific to pregnancy. Many other things — colds, hay fever, and indoor allergens — cause nasal congestion too. A missed period and a positive pregnancy test are far more reliable indicators of pregnancy. If you have a blocked nose alongside other early pregnancy symptoms such as breast tenderness, fatigue, or nausea, it may be worth taking a test.

Can I use decongestants in pregnancy?

Some decongestant ingredients are considered safer than others, and recommendations can differ depending on your stage of pregnancy and your overall health. Always consult your midwife or pharmacist before using any nasal medication during pregnancy, including nasal sprays, drops, or oral decongestants. Saline sprays are a safe starting point that does not carry the same risks.

Always speak to your midwife or GP for personal advice about symptoms in pregnancy.
