Sinusitis in pregnancy

Overview

Sinusitis is inflammation (swelling) of the sinuses, which are small, air-filled spaces behind your forehead, cheeks, and eyes. During pregnancy, your body makes more hormones that can swell the lining of your nose and sinuses, making it easier for them to get blocked and infected.

Yes, sinusitis is common in pregnancy. Hormonal changes cause swelling in your nasal passages, which can block the sinuses. Also, your immune system is slightly different during pregnancy, making you more likely to catch colds that can lead to sinusitis.

Pregnant people in any trimester, but it's most common in the second and third trimesters when hormone levels are highest.

Symptoms

Common symptoms

• Stuffy or runny nose that does not get better
• Pain or pressure in your face, especially around your eyes, cheeks, or forehead
• Headache that is worse when you lean forward
• Thick yellow or green mucus from your nose or down your throat
• A reduced sense of smell
• Cough, especially at night
• Fever (temperature above 100.4°F or 38°C)
• Bad breath or toothache

Causes

Main causes

• Viral infections – like the common cold – that cause the sinus lining to swell and trap mucus
• Hormonal changes during pregnancy that naturally swell the lining of your nose and sinuses
• Bacterial infection if blocked sinuses do not drain properly (less common)

Risk factors

• Being pregnant (especially in the second trimester)
• Having allergies year-round
• Smoking or being around secondhand smoke
• Using nasal decongestant sprays too often (more than 3 days)
• Having a weak immune system from another condition

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency warning signs (severe headache with stiff neck, eye swelling, vision changes, trouble breathing, confusion)
• If you have a fever above 101°F (38.3°C) that does not improve
• If you are having trouble breathing or your chest feels tight

Book a routine appointment if:

• If your symptoms last longer than 10 days without getting better
• If you have recurrent sinus trouble (more than 2 or 3 times in a year)
• If you are unsure which treatments are safe to use during pregnancy
• If you have a history of sinus surgery or complications

Diagnosis

Your doctor will ask about your symptoms and how long you have had them. They will examine your nose and sinuses using a small light and may gently press on your face to check for tenderness. In most cases, no special tests are needed.

Tests that may be done

• If symptoms are severe or unclear, the doctor may use a thin, lighted tube (nasal endoscopy) to look inside your nose.
• Rarely, imaging like an X-ray or CT scan is needed, but these are usually avoided during pregnancy unless absolutely necessary. An ultrasound of the sinuses may be an option.

What to expect at your appointment

Your doctor will rule out other causes like allergies or a cold. They will recommend safe treatments and tell you which symptoms to watch for. You may be referred to an ear, nose, and throat specialist if the infection does not improve.

Treatment

Treatment for sinusitis in pregnancy focuses on relieving your symptoms while keeping your baby safe. Many cases get better without medicine. If you need treatment, your doctor will choose options that are known to be safe during pregnancy.

Self-care at home

• Use a cool-mist humidifier in your bedroom to add moisture to the air
• Breathe in steam from a warm shower or bowl of hot water (keep face at a safe distance)
• Apply warm, damp cloths to your face for several minutes to ease pain
• Drink lots of fluids like water and herbal tea to thin mucus
• Use a saline (salt water) nasal spray or rinse to clear your nose
• Sleep with your head propped up on extra pillows to help drainage
• Rest as much as you can to help your body fight the infection

Medical treatments

If self-care is not enough, your doctor may recommend a nasal steroid spray that is safe in pregnancy. For bacterial sinusitis (rare), they may prescribe an antibiotic that is known to be safe. Pain and fever can usually be managed with paracetamol (acetaminophen) at the dose your doctor advises. Never take ibuprofen or other nonsteroidal anti-inflammatory drugs (NSAIDs) in late pregnancy unless your doctor specifically says it is okay.

When is surgery considered?

Surgery for sinusitis is almost never needed during pregnancy. It is only considered for very rare complications, such as an abscess that does not drain. If surgery is necessary, it is usually postponed until after the baby is born.

Living with this condition

Most pregnant people with sinusitis can continue their normal daily activities, though you may need more rest. The symptoms often improve after the first few days of self-care. If you feel very unwell, take time off from work and ask for help at home.

Lifestyle tips

• Avoid smoke and strong chemicals that can irritate your nose
• Use a saline nasal spray regularly to keep your nose moist
• Keep your home clean to reduce dust and pet dander
• Wash your hands often to avoid picking up new viruses

Diet and exercise

Eat a balanced diet rich in fruits and vegetables to support your immune system. Drink plenty of water and warm liquids like soup or tea. Gentle exercise such as walking can help you feel better, but do not push yourself if you are tired. Always check with your doctor before starting any new exercise routine during pregnancy.

Mental health and emotional wellbeing

Being sick while pregnant can be frustrating and tiring. The constant nasal congestion and facial pain may disturb your sleep, which can affect your mood. It's normal to feel a bit down or anxious. Talk to your partner, family, or friends about how you feel. If you notice sadness that does not lift, or if you have thoughts of harming yourself or your baby, contact your doctor immediately or call emergency services. Remember, help is available.

Prevention

You cannot completely prevent sinusitis, but you can lower your risk. Avoid catching colds by washing your hands frequently and staying away from people who are sick. Use a humidifier in dry indoor air to keep your nasal passages moist. If you have allergies, manage them with safe treatments recommended by your doctor.

Complications

If left untreated

• Bacterial sinusitis can spread to the eye socket (orbital cellulitis), causing swelling, pain, and vision problems – this is a medical emergency.
• Very rarely, infection can spread to the brain and spinal cord (meningitis), causing severe headache, stiff neck, and fever.
• Prolonged sinusitis may lead to chronic sinus problems after pregnancy.

Long-term outlook

For the vast majority of pregnant people, sinusitis gets better with simple home care and without any harm to you or your baby. Even if you need treatment, there are safe options. Most cases resolve completely within a few weeks. With proper care, you can manage the symptoms comfortably and focus on a healthy pregnancy.
