preventing sinus infection

Overview

A sinus infection is inflammation or swelling of the tissue lining your sinuses. It happens when your sinuses become blocked and fill with fluid, allowing germs to grow.

Yes, sinus infections are very common. Many people get them after a cold or allergy flare-up.

Sinus infections can affect anyone, but they are most common in adults. People with allergies, asthma, a weakened immune system, or structural issues in the nose may get them more often.

Symptoms

Common symptoms

• Nasal congestion and stuffiness
• Thick, yellow or green mucus from the nose or down the throat
• Facial pain, pressure or fullness in the cheeks, forehead or around the eyes
• Headache
• Reduced sense of smell
• Cough or sore throat
• Bad breath

Symptoms in children

• Cold-like symptoms that last more than 10 days
• Runny nose or daytime cough
• Irritability or tiredness
• Fever may or may not be present

Symptoms in older adults

• Less specific symptoms like fatigue or confusion
• May not have a fever
• Symptoms may appear gradually

Causes

Main causes

• Viral infections, such as the common cold
• Bacterial infections (after a viral infection weakens your sinuses)
• Fungal infections (rare, usually in people with very weak immune systems)

Risk factors

• Allergies or hay fever
• Nasal polyps or a deviated septum
• Smoking or being around smoke
• A weakened immune system
• Frequent colds or respiratory infections

When to see a doctor

See a doctor urgently if:

• The symptoms listed in the emergency or urgent care section above
• Facial pain or pressure that is severe or worsening
• A high temperature that lasts more than 3 days

Book a routine appointment if:

• Symptoms that do not improve after 10 days
• Symptoms that go away and then return
• You have had sinus infections several times in the past year

Diagnosis

Your doctor will ask about your symptoms and examine your nose, throat and face. In most cases, no special tests are needed.

Tests that may be done

• A look inside your nose with a small light or camera (nasal endoscopy)
• Imaging tests like a CT scan if symptoms are severe or long-lasting
• Allergy tests if allergies are suspected
• A nasal swab to identify the cause in some cases

What to expect at your appointment

Your doctor will gently press on your face to check for tenderness. You may be asked to sit up and lean forward slightly. The exam is quick and painless.

Treatment

Treatment depends on whether your sinus infection is caused by a virus, bacteria, or another trigger. Most people can manage symptoms at home without needing a prescription.

Self-care at home

• Rest and drink plenty of fluids
• Use a saline (salt water) nasal spray or rinse to keep your nose moist
• Breathe in steam from a bowl of warm water or a warm shower
• Place a warm, damp cloth over your face for comfort
• Avoid flying or quickly changing altitudes until you feel better

Medical treatments

Your doctor may suggest over-the-counter medicines to relieve pain or fever, decongestants to reduce stuffiness, or saline rinses. If a bacterial infection is confirmed or strongly suspected, your doctor may prescribe antibiotics. They will decide whether that is needed. Follow their instructions and finish the full course if they are prescribed.

When is surgery considered?

Surgery is rarely needed. It may be considered for people with chronic sinusitis, nasal polyps, or structural issues that do not improve with other treatments.

Living with this condition

While you recover, focus on comfort and rest. Keep your head elevated when sleeping to ease pressure. Drink water regularly and avoid irritants like smoke or strong perfumes.

Lifestyle tips

• Use a humidifier in your home to keep the air moist
• Wash your hands often, especially during cold season
• Avoid touching your face with unwashed hands
• Manage your allergies with the help of your doctor

Diet and exercise

Eat a balanced diet with plenty of fruits and vegetables. Gentle exercise like walking may help you feel better as long as you are not too unwell. Listen to your body and rest when you need to.

Mental health and emotional wellbeing

Living with recurring sinus infections can be frustrating and may disrupt your sleep, work, and mood. If you feel anxious or down, talk to your doctor. You do not have to face it alone.

Prevention

You cannot always prevent sinus infections, but you can reduce your risk by keeping your nose clear, managing allergies, avoiding irritants, and practicing good hand hygiene.

Vaccines

Some vaccines, such as the flu vaccine and certain pneumonia vaccines, can help prevent respiratory infections that may lead to sinusitis. Ask your doctor or local health service which vaccines are recommended for you.

Screening programmes

There is no routine screening for sinus infection. Regular check-ups with your doctor can help catch and manage conditions that increase your risk.

Complications

If left untreated

• Chronic sinusitis (long-lasting inflammation)
• Spread of infection to nearby areas, such as the eye or brain (very rare)
• Worsening symptoms or longer recovery

Long-term outlook

The outlook is very good. Most sinus infections clear up on their own within two to three weeks, and even chronic cases can be managed well with medical and self-care. With the right support, most people feel much better.
