What is a nasal obstruction?

A nasal obstruction is a blockage or narrowing of the nasal passages that makes it difficult to breathe through your nose. It’s not a specific disease, but rather a symptom of an underlying condition

Imagine your nose like a hallway in your house. Normally, air flows freely through this hallway when you breathe. But if something blocks or narrows the hallway, it becomes harder for air to pass through. That’s essentially what happens with a nasal obstruction.

Types of Nasal Obstruction

Nasal obstruction, also known as a stuffy nose, refers to a blockage or narrowing of the nasal passages that makes it difficult to breathe through your nose. It’s not a specific disease, but rather a symptom of an underlying condition. Several factors can cause nasal obstruction, ranging from temporary issues like colds and allergies to chronic conditions like deviated septum and nasal polyps. Here’s a closer look at some of the most common types:

Deviated septum:

Deviated septum nasal obstruction

The nasal septum is the thin cartilage wall that divides the nose into two nostrils. A deviated septum occurs when this wall is crooked, often due to injury or trauma. This can narrow one or both nasal passages, leading to chronic difficulty breathing through the nose, especially on one side. Other symptoms may include frequent sinus infections, facial pain or pressure, and nosebleeds.

Inferior turbinate hypertrophy:

Inferior turbinate hypertrophy nasal obstruction

The turbinates are bony structures located inside the nasal cavity that help warm and humidify the air we breathe. When these structures become enlarged, usually due to allergies or chronic inflammation, they can block the nasal passages and cause difficulty breathing. Symptoms include nasal congestion, runny or stuffy nose, and postnasal drip.

Choanal atresia:

Choanal atresia nasal obstruction

Choanal atresia is a rare congenital malformation where a bony or membranous plate blocks one or both of the nasal passages at the back of the nose. This can prevent newborns from breathing through their nose, causing them to experience difficulty feeding and cyanosis (bluish skin color). Early diagnosis and treatment are crucial for ensuring proper breathing and development.

Nasal polyps:

Nasal polyps nasal obstruction

Nasal polyps are small, non-cancerous growths that form in the lining of the nasal passages or sinuses. They are often associated with allergies, chronic sinusitis, and asthma. While typically painless, nasal polyps can cause nasal obstruction, runny or stuffy nose, loss of smell or taste, and facial pain or pressure.

Foreign objects in the nose:

Foreign objects in the nose nasal obstruction

This is a more common occurrence in children who may put small objects like beads, toys, or food particles up their nose. The presence of a foreign object can cause immediate nasal obstruction, bleeding, and pain. If you suspect a foreign object in someone’s nose, seek immediate medical attention.

Enlarged adenoids:

Enlarged adenoids nasal obstruction

Adenoids are small pads of tissue located in the back of the nasal cavity that help fight infection. In children, adenoids can sometimes become enlarged due to frequent infections or allergies. This enlargement can block the nasal passages and cause difficulty breathing, snoring, and mouth breathing.


Sinusitis nasal obstruction

Sinusitis is inflammation of the sinuses, the air-filled cavities located around the nose and eyes. When the sinuses become inflamed, they can produce mucus that blocks the drainage pathways and leads to nasal congestion, facial pain or pressure, and fever.

Allergic rhinitis:

Allergic rhinitis nasal obstruction

Allergic rhinitis, also known as hay fever, is an allergic reaction to airborne allergens like pollen, dust, or mold. It triggers an inflammatory response in the nose, causing congestion, runny nose, sneezing, and itchy eyes.

Other causes:

Other less common causes of nasal obstruction include tumors, nasal bone fractures, and certain medications.

Causes of nasal obstruction

Temporary causes: These are the most common and often resolve on their own within a few days. They include:

Colds and flu: Viruses cause inflammation and swelling in the nasal tissues, leading to congestion.

Allergies: Exposure to allergens like pollen, dust, or mold triggers an inflammatory response in the nose, causing swelling and mucus production.

Sinus infections: Bacterial or viral infections in the sinuses can cause congestion and block the drainage pathways, leading to nasal obstruction.

Environmental irritants: Smoke, dust, and strong chemicals can irritate the nasal lining and cause swelling and congestion.

Chronic causes: These obstructions may require medical attention or surgery to address. They include:

Deviated septum: This is a condition where the cartilage separating the nostrils is crooked, narrowing one or both nasal passages.

Nasal polyps: These are small, non-cancerous growths in the nasal lining that can block the passages.

Enlarged adenoids: These are lymph tissue pads in the back of the nose that can enlarge in children and block the passage of air.

Anatomical anomalies: Some people are born with abnormalities in their nasal structure that can cause obstruction.

Tumors: Although rare, tumors in the nose or sinuses can block the nasal passages.

Symptoms of nasal obstruction

Difficulty breathing through the nose

Stuffy or blocked feeling in the nose

Runny or stuffy nose


Mouth breathing

Facial pain or pressure

Loss of smell or taste

Difficulty sleeping

Nasal obstruction diagnosis

Diagnosing the cause of nasal obstruction often involves a combination of approaches, as there are several potential sources of the problem. Here’s a breakdown of the typical steps involved:

Medical history and symptom evaluation:

Your doctor will begin by asking about your symptoms, including the duration and severity of your blocked nose, any associated symptoms like runny nose, facial pain, fever, or loss of smell, and potential triggers like allergens or irritants.

They will also inquire about your medical history, including any previous diagnoses of allergies, sinusitis, or nasal polyps, and any surgeries or injuries to the nose.

Physical examination:

Your doctor will examine your nose, both externally and internally using an otoscope or nasoscope. This allows them to assess for nasal deformities, swelling, mucus discharge, polyps, or any abnormalities in the nasal passages.

They may also palpate your sinuses for tenderness or pain.

Additional investigations:

Depending on the initial findings, further investigations may be necessary to reach a definitive diagnosis. Some common tests include:

Rhinoscopy: A more detailed examination of the nasal passages and sinuses using a flexible endoscope.

Sinus X-ray or CT scan: To visualize the sinuses and look for evidence of inflammation or blockage.

Allergy testing: Skin prick tests or blood tests to identify potential allergens triggering your symptoms.

Nasal endoscopy with biopsy: In rare cases, if polyps or other suspicious growths are present, a biopsy may be needed to determine their nature.

Interpretation and diagnosis:

Based on the information gathered from the history, examination, and any additional tests, your doctor will then diagnose the underlying cause of your nasal obstruction. This could be anything from a simple cold to a chronic condition like deviated septum or nasal polyps.

Important factors to consider:

The diagnosis process may be quicker in cases with clear symptoms and obvious findings.

Some conditions may share similar symptoms, requiring more thorough investigations to differentiate.

Timely and accurate diagnosis is crucial for determining the appropriate treatment approach.

If you have any concerns about your nasal obstruction, it’s always best to consult with a doctor for proper diagnosis and guidance. Don’t hesitate to ask your doctor any questions you may have about the process or potential causes of your blocked nose.

Nasal obstruction treatment

Treatment for nasal obstruction depends heavily on the underlying cause and severity of your symptoms. Here’s a breakdown of potential approaches:

Home remedies for temporary causes:

Saline nasal sprays: These sprays help thin mucus and clear the nasal passages. Use distilled water and saline packets or pre-made solutions.

Warm compresses: Apply a warm compress to your nose and forehead for 10-15 minutes to ease congestion and promote drainage.

Humidifier: Adding moisture to the air can help loosen mucus and make it easier to breathe.

Over-the-counter medications: Consider decongestants for short-term relief, but avoid using them for more than a few days to prevent rebound congestion.

Elevation: Sleeping with your head slightly elevated can help improve drainage and reduce congestion.

Medical treatments for chronic or severe cases:

Topical nasal steroids: These sprays reduce inflammation in the nasal passages and are effective for managing allergies and chronic sinusitis.

Antihistamines: If allergies are the culprit, oral or nasal antihistamines can help alleviate symptoms like sneezing, runny nose, and itchy eyes.

Antibiotics: For bacterial sinusitis, antibiotics may be prescribed to clear the infection.

Surgery: In some cases, surgery may be necessary to address structural problems like a deviated septum or enlarged turbinates.

Additional treatment options:

Nasal irrigation: Using a neti pot or bulb syringe with saline solution can flush out mucus and allergens from the nasal passages.

Allergy immunotherapy: This involves receiving injections or sublingual tablets containing small amounts of the allergen to gradually desensitize your immune system.

Radiofrequency ablation: This minimally invasive procedure uses radio waves to shrink enlarged turbinates and improve airflow.


Always consult with your doctor before starting any new medication or treatment, especially if you have other medical conditions.

Be aware of potential side effects and interactions with other medications.

Follow your doctor’s instructions carefully for optimal results.

Remember, nasal obstruction is rarely a life-threatening condition, but it can significantly impact your quality of life. If it’s persistent or causing you discomfort, seeking medical advice is crucial for identifying the cause and finding the most effective treatment approach.

What is the best treatment for nasal blockage?

Unfortunately, there’s no single “best” treatment for nasal blockage, as the optimal approach depends entirely on the underlying cause and the severity of your symptoms. Here’s why:

Different causes require different solutions:

Temporary issues like colds or allergies: Home remedies like saline sprays, humidifiers, and over-the-counter decongestants might be sufficient to clear congestion.

Chronic conditions like deviated septum or nasal polyps: These may require medications or even surgery to address the structural cause.

Bacterial sinusitis: Antibiotics are necessary to clear the infection, while other symptoms may be managed with home remedies and pain relievers.

Severity plays a role:

Mild congestion: Simple home remedies might provide adequate relief.

Severe blockage impacting daily life: Medical intervention like prescription medications or surgery might be necessary for improvement.

Therefore, a more helpful approach would be to consider the most likely cause of your nasal blockage based on your symptoms and history. Here are some examples:

If you have a cold or flu:

Try: Saline nasal spray, warm compresses, humidifier, over-the-counter decongestants (short-term), plenty of fluids, rest.

See a doctor if: Symptoms worsen or persist beyond a week, fever develops, facial pain becomes severe.

If you suspect allergies:

Try: Saline nasal spray, nasal steroids, antihistamines.

See a doctor if: Symptoms are severe or don’t improve with OTC medications, you have trouble breathing or wheezing.

If you have chronic sinusitis:

Try: Saline nasal spray, nasal steroids, over-the-counter pain relievers, warm compresses.

See a doctor if: Symptoms worsen or persist, you have facial pain or pressure, foul-smelling discharge, fever.

Always consult your doctor for proper diagnosis and treatment.

Avoid self-medicating for extended periods without medical advice.

Be honest about your symptoms and medical history during consultations.

By working with your doctor and understanding the underlying cause, you can find the most effective treatment for your specific nasal blockage situation.
