Blocked nose during pregnancy

Hormonal changes can make the lining inside the nose more swollen and sensitive. This may cause congestion, a runny nose, post-nasal drip or mouth breathing without a cold. Sneezing and itchy eyes suggest allergic rhinitis; fever, sore throat or body aches suggest an infection such as a common cold. Facial pain, worsening pressure or thick discharge can occur with sinusitis. Nasal blockage may also make sleep and snoring worse.

Try a saline spray or rinse, drink fluids and avoid smoke, strong fragrances and known allergy triggers. Sleeping with your head slightly raised may ease night-time congestion. Ask your obstetric clinician or pharmacist before taking any tablet, nasal spray or herbal product; pregnancy changes which medicines are suitable. Do not use a decongestant regularly without professional advice, and do not stop prescribed medicines without discussing them.

Seek urgent help for severe breathing difficulty, chest pain, facial or throat swelling, fainting, or inability to keep fluids down. Contact your maternity team or doctor for fever, severe facial pain, worsening illness, dehydration, symptoms that persist, or congestion that prevents sleep despite simple measures. Mention reduced fetal movement or any other pregnancy concern promptly through your usual maternity service.

Ask whether the pattern fits pregnancy-related congestion, allergy or infection; which saline and medicine options are suitable; and whether snoring or poor sleep needs assessment.
