17980 Nasal Congestion

Overview

Nasal congestion is a stuffy or blocked nose. It happens when the tissues inside your nose become swollen and make extra mucus. This can make it hard to breathe through your nose. It is usually caused by a cold, allergies, or irritation.

Yes. Almost everyone experiences nasal congestion at some point. It is one of the most common reasons for a visit to a general practice.

People of all ages get nasal congestion, from babies to older adults. It can be more frequent in children because their noses are smaller and their immune systems are still learning. It is also more common in people with allergies.

Symptoms

Common symptoms

• Stuffy or blocked nose
• Difficulty breathing through the nose
• Runny nose or mucus dripping down the back of the throat
• Pressure or discomfort in the face, forehead, or around the eyes
• Reduced sense of smell or taste
• Mild headache

Symptoms in children

• Children may breathe through their mouth, snore, or have trouble feeding because they cannot breathe while sucking.
• A child may be fussy, have a mild fever, or rub their nose and eyes.
• Babies with a blocked nose may feed poorly or wake often at night.

Symptoms in older adults

• Older adults may notice a blocked nose that lasts longer or takes more time to clear.
• They may have more mucus or post-nasal drip, which can cause a cough or sore throat.
• Nasal congestion can make dry mouth worse, especially when sleeping.

Causes

Main causes

• Viral infections, such as the common cold or flu
• Allergies to pollen, dust mites, or pet dander
• Sinusitis, which is inflammation of the sinuses
• Sensitivity to smoke, strong smells, or dry air
• Structural issues, such as a deviated septum — a bend in the wall inside the nose
• Hormonal changes, including pregnancy

Risk factors

• Attending school or daycare
• Smoking or being around secondhand smoke
• Known allergies
• Asthma or eczema
• A weakened immune system

When to see a doctor

See a doctor urgently if:

• Symptoms lasting more than 10 to 14 days without improvement
• One-sided nasal blockage with blood-stained discharge
• Vision changes, severe headache, or swelling around the eye

Book a routine appointment if:

• Frequent or recurring congestion that interferes with sleep or daily life
• Suspected allergy that does not improve with simple measures
• Nasal congestion during pregnancy that bothers you

Diagnosis

A doctor or nurse will ask about your symptoms, how long they have lasted, and any triggers. They will look inside your nose using a small light. In most cases, no tests are needed.

Tests that may be done

• A physical examination of the nose, throat, and face
• Allergy tests if an allergy is suspected
• A nasal swab if an infection needs checking
• Imaging, such as a sinus X-ray or CT scan, only if symptoms are persistent or complicated

What to expect at your appointment

The appointment is usually quick. The doctor may press gently on your face and look into your nose. They will explain what might be causing the congestion and suggest safe next steps. You may receive advice on home care, and if needed, a referral to an ear, nose, and throat specialist.

Treatment

Treatment focuses on relieving symptoms and treating the cause if it is known. Most cases improve with home care alone. If allergies, infection, or another condition is present, your healthcare team can guide you.

Self-care at home

• Drink plenty of water to keep mucus thin.
• Breathe steam from a warm shower or a bowl of hot water to moisten your nasal passages.
• Use a saltwater (saline) nasal spray or rinse to help clear mucus.
• Rest and sleep with your head raised on extra pillows.
• Use a cool-mist humidifier in the room.
• Avoid smoky, dusty, or strongly scented environments.

Medical treatments

If your congestion is caused by allergies, a doctor may suggest allergy medications or nasal sprays that reduce swelling. For a bacterial sinus infection, a doctor may prescribe antibiotics — but only when needed. Your doctor or pharmacist can explain which over-the-counter options are safe for you. Do not use decongestant sprays for more than a few days without medical advice, because they can make congestion worse if used too long.

When is surgery considered?

Surgery is rarely needed for nasal congestion alone. If the cause is a structural problem, such as a severely blocked nasal passage or large nasal polyps that do not improve with treatment, a specialist may discuss surgical options. This is only after other treatments have been tried.

Living with this condition

You can manage most nasal congestion at home. Keep a tissue nearby, stay hydrated, and avoid triggers that make it worse. If symptoms linger, keep a simple diary of when they happen — this can help you and your healthcare team spot patterns.

Lifestyle tips

• Wash your hands often to reduce your chance of catching colds.
• Avoid smoking and secondhand smoke.
• If allergies are the cause, keep windows closed during high pollen seasons and use an air filter.
• Use a saline rinse before sleep to make nighttime breathing easier.

Diet and exercise

There is no special diet for nasal congestion, but staying well hydrated helps keep mucus looser. Warm fluids such as soup can be soothing. Light exercise like walking is usually safe if you feel up to it, but rest when you are tired. If you have a fever or feel unwell, give yourself time to recover.

Mental health and emotional wellbeing

A stuffy nose can disrupt sleep and make it hard to focus. It can be frustrating, especially if it lasts. Most people feel better within a week or two. If congestion is keeping you from daily activities or making you feel low, mention it to your doctor.

Prevention

It is not always possible to prevent nasal congestion, but you can reduce your risk. Avoid known allergy triggers, wash your hands often, and avoid close contact with people who have colds. Staying up to date with recommended vaccinations, including the flu shot, may also help prevent infections that cause congestion.

Vaccines

Flu and other routine vaccinations can help protect you from viral infections that often cause nasal congestion. Ask your local health service which vaccinations are recommended for your age and health situation.

Screening programmes

No routine screening exists for nasal congestion. If you have frequent symptoms, your doctor can investigate the underlying cause.

Complications

If left untreated

• Sleep problems and daytime tiredness
• Sinusitis, which is inflammation or infection of the sinuses
• Ear infections or hearing problems, especially in children
• Changes in sense of smell or taste

Long-term outlook

The outlook for nasal congestion is very good. Most cases clear within a week or two with simple home care. Even when caused by allergies or other ongoing conditions, there are effective ways to manage symptoms and keep you breathing comfortably. With the right support, you can reduce how often it happens and how much it affects your day.
