17950 Nonallergic Rhinitis

Overview

Nonallergic rhinitis is a condition where the inside of your nose becomes inflamed, causing symptoms like a stuffy or runny nose. Unlike allergic rhinitis (hay fever), it is not caused by an allergic reaction. Instead, triggers like weather changes, strong smells, or smoke can set off the symptoms.

Yes, nonallergic rhinitis is very common. It is believed to affect around 20% of adults at some point.

It can affect people of any age, but it is most often diagnosed in adults over 20. Women are affected more frequently than men, and certain occupations with chemical or dust exposure may increase the risk.

Symptoms

Common symptoms

• A runny nose that is usually clear
• Nasal congestion or stuffiness
• Post-nasal drip (mucus dripping down the back of your throat)
• Sneezing
• A reduced sense of smell

Symptoms in children

• Constant sniffles without signs of a cold
• Mouth breathing during the day and snoring at night
• Nasal congestion that makes feeding or speaking difficult
• Recurrent mild nosebleeds
• Dry cough, especially at night

Symptoms in older adults

• Long-lasting nasal congestion
• Post-nasal drip that relates to a dry or scratchy throat
• Disturbed sleep due to difficulty breathing through the nose
• Worsening symptoms when taking certain blood pressure tablets (talk to your doctor)
• Increased tendency to sinus infections

Causes

Main causes

• Changes in temperature, humidity, or air pressure
• Exposure to irritants like car exhaust, industrial chemicals, cigarette smoke, or strong perfumes
• Certain medicines, such as some blood pressure medications or overuse of nasal decongestant sprays
• Hormonal changes, such as those during pregnancy or thyroid disorders
• Stress and emotional factors
• Spicy foods or alcohol, in some people
• Structural issues inside the nose, such as a deviated septum (a bend in the bone and cartilage dividing the nose)

Risk factors

• Being over the age of 20
• Being female — nonallergic rhinitis is twice as common in women
• Working in environments with dust, fumes, or strong chemicals
• Smoking or being around secondhand smoke
• Having chronic sinusitis or nasal polyps
• Using decongestant nasal sprays for more than a few days in a row

When to see a doctor

See a doctor urgently if:

• Severe symptoms that do not improve with self-care
• Another nosebleed or visible bleeding after a minor injury
• Symptoms that suggest a possible infection, such as a high fever, sinus pressure, or discolored mucus

Book a routine appointment if:

• Symptoms that last more than 4 weeks and are affecting your day-to-day life
• If you are taking over-the-counter remedies with little or no benefit
• If you need to miss work or school because of your symptoms

Diagnosis

There is no single test for nonallergic rhinitis. A doctor will ask about your symptoms, when they happen, and your possible triggers. They will look inside your nose with a light or a small camera to check for swelling and structural problems.

Tests that may be done

• A physical exam of your nose with a nasal speculum
• Allergy testing (skin or blood tests) to rule out allergies
• A nasal endoscopy (a thin, flexible tube with a camera) for a more detailed look
• If sinus infections or other conditions are suspected, a CT scan of your sinuses

What to expect at your appointment

Your appointment may take 30 minutes. The doctor will ask you to describe your symptoms and may spray a decongestant in your nose to see how your airways respond. You will get a clear explanation of what might be causing your symptoms and what steps you can take next.

Treatment

Treatment focuses on reducing your symptoms and avoiding the things that trigger your nose. Most people use a combination of self-care, prescription sprays, and medications to manage flare-ups. For many, symptoms become much less noticeable within a few weeks of starting the right routine.

Self-care at home

• Rinse your nose daily with a salt-water (saline) spray or nasal rinse. You can buy a ready-made rinse at most pharmacies.
• Keep the air in your bedroom moist with a cool-mist humidifier, especially in winter.
• Avoid strong perfumes, cleaning products, smoke, and other chemical irritants.
• Stay well-hydrated during the day to thin your nasal mucus.
• Use a warm facecloth over your sinuses to ease pressure.
• Prop your head up with an extra pillow at night to help drainage.

Medical treatments

Depending on your symptoms, your healthcare provider may recommend a nasal corticosteroid spray (a spray that reduces swelling), a nasal antihistamine spray, or a medicine that dries up excess fluid. Oral decongestants are sometimes used for short periods. These are prescription-only for some people. Always ask your doctor or pharmacist for guidance. Do not use an over-the-counter nasal decongestant spray for more than 5 days unless advised, as overuse can make symptoms worse.

When is surgery considered?

In rare cases, when symptoms are linked to a structural problem like a deviated septum, surgery to straighten the septum (septoplasty) may be suggested. Surgery is not a first-line treatment and is only considered when other options have not worked.

Living with this condition

You may have more good days than bad ones once you learn your triggers. Keeping a simple diary of your symptoms, weather, and exposures can help you spot patterns and avoid them.

Lifestyle tips

• Use a saline spray before going outside on very cold or very hot days.
• Wearing sunglasses outdoors can help shield your eyes and nose from cold air and airborne irritants.
• If you are a smoker, quitting is one of the most helpful steps. Your pharmacist can provide support.
• Consider a nasal saline rinse after being in a dusty or smoky environment.
• Take a warm shower before bed to open your nasal passages and reduce congestion.

Diet and exercise

Regular physical activity can naturally reduce nasal congestion by increasing your breathing rate and opening your airways. No specific diet is proven to treat nonallergic rhinitis, but avoiding spicy foods or alcohol in the evening may help if these are personal triggers. A balanced diet supports your overall immune system.

Mental health and emotional wellbeing

Living with a constantly runny or blocked nose can be frustrating and tiring. It may affect your sleep, concentration, and how you interact with others. This can sometimes lead to low mood or anxiety. These feelings are normal, and it is worth talking about them with your doctor. They can help you adjust your treatment plan.

Prevention

Nonallergic rhinitis cannot always be prevented, but you can reduce how often you get symptoms by avoiding your known triggers. This includes keeping a clean, smoke-free home, using gentle cleaning products, and controlling dust and humidity.

Vaccines

There is no vaccine for nonallergic rhinitis, but it is sensible to stay up to date with your flu and COVID-19 vaccines, as any respiratory infection can make nasal symptoms worse.

Screening programmes

There is no routine screening test for this condition. Your doctor will only investigate if you have concerning symptoms.

Complications

If left untreated

• Chronic sinusitis (ongoing sinus inflammation and infection)
• Nasal polyps (soft, painless growths inside the nasal passages)
• Recurrent ear infections in children
• Poor sleep quality and daytime fatigue due to nasal congestion
• Rarely, a decrease in sense of smell or taste

Long-term outlook

With the right approach, most people with nonallergic rhinitis find their symptoms become mild and manageable. It is a long-term condition for many, but it does not shorten life or cause permanent damage. Be patient and follow your treatment plan—you can expect a much better quality of life.
