Experiencing difficulty breathing through your nose is a widespread issue that prompts many individuals to seek medical advice from primary care physicians, allergists, or otolaryngologists (ENT doctors). If you’re frequently asking yourself, “why can’t I breathe through my nose?”, it’s important to understand that nasal obstruction and chronic sinusitis are often the primary culprits. Both conditions can significantly impact your breathing comfort and overall quality of life.
While both nasal obstruction and chronic sinusitis can hinder nasal breathing, they are distinct conditions with different underlying causes and characteristics. Understanding the differences is key to seeking the right diagnosis and effective treatment.
Nasal Obstruction: When Your Nasal Passages are Blocked
Nasal obstruction refers to any blockage within your nasal cavity or nose. This blockage can arise from a variety of factors, and in many instances, it’s a temporary inconvenience due to common conditions like allergies, colds, certain medications, or sinus infections. However, some nasal obstructions are more persistent and require medical intervention to resolve.
Research published by the National Institutes of Health highlights the prevalence of structural issues contributing to nasal obstruction. A study revealed that among patients surveyed, septal deviation was found in 76%, inferior turbinate hypertrophy in 72%, and nasal valve collapse in 67%. These anatomical variations can significantly impede airflow through the nasal passages.
Nasal obstruction is a frequent reason for visits to primary care physicians and ENT specialists. Beyond the discomfort of labored breathing, it can have substantial consequences. It’s a significant factor in obstructive sleep apnea (OSA), severely impacting sleep quality. For athletes, nasal obstruction can hinder their ability to perform at their peak due to reduced oxygen intake.
Common Causes of Nasal Obstruction
Several conditions can lead to nasal obstruction, each with its own mechanisms and characteristics:
-
Deviated Nasal Septum: The nasal septum, the wall dividing your nostrils, isn’t always perfectly straight. A deviated septum, where this wall is significantly crooked, is quite common. While many people have some degree of deviation, more pronounced cases can cause noticeable symptoms like a constantly runny nose and difficulty breathing through one or both nostrils.
-
Choanal Atresia: This is a congenital condition, meaning it’s present from birth. Choanal atresia involves extra tissue in the nasal airway that creates a partial or complete blockage, making nasal breathing challenging for infants and children.
-
Inferior Turbinate Hypertrophy: Turbinates are bony structures within the nasal cavity that are lined with soft tissue. They play a crucial role in humidifying and filtering the air you breathe. However, turbinates are susceptible to irritation from allergens and dust, leading to swelling (hypertrophy). This swelling narrows the nasal passages, causing breathing difficulties.
-
Nasal Polyps: These are soft, noncancerous growths that develop on the lining of your sinuses or nasal passages. Often painless, nasal polyps can grow large enough to obstruct airflow and contribute to breathing problems.
-
Swelling due to Allergies: Allergic rhinitis, or allergies, is a common cause of nasal congestion. Allergens trigger inflammation and swelling of the nasal lining, resulting in nasal obstruction.
-
Enlarged Adenoids: Adenoids are glands located in the roof of your mouth, behind your nose. Particularly in children, enlarged adenoids can obstruct the nasal passages, leading to breathing difficulties and snoring.
-
Foreign Objects in the Nose: Especially common in young children, foreign objects like small toys, food particles, or beads can become lodged in the nasal cavity, causing a blockage and difficulty breathing through the nose.
-
Nasal Valve Stenosis: The nasal valve is the narrowest part of your nasal passage, located in the soft tissue area inside your nose. It’s often the primary site of nasal obstruction because of its narrow structure. Nasal valve stenosis refers to the narrowing or collapse of this area. This can be caused by:
- Weakness in nasal cartilage and soft tissue: Weakness in these structures can lead to collapse, particularly during inhalation.
- Developmental Narrowing: Some individuals naturally have a narrower nasal valve.
- Prior Nasal Procedures: Surgeries like rhinoplasty can sometimes inadvertently weaken the cartilage supporting the nasal valve, leading to collapse.

Chronic Sinusitis: Inflammation and Blockage of the Sinuses
Chronic sinusitis, in contrast to nasal obstruction, is characterized by inflammation of the sinuses that lasts for an extended period. Sinusitis itself involves inflammation causing pressure, pain, and swelling in the sinus cavities. When this condition persists for longer than 12 weeks, it is classified as chronic sinusitis. It’s important to note that unlike acute sinusitis, which is often triggered by a bacterial infection, chronic sinusitis is less frequently caused by bacteria and typically doesn’t respond to standard antibiotic treatments. Chronic sinusitis is also frequently referred to as chronic rhinosinusitis, reflecting the involvement of both the nasal passages and sinuses.
The Centers for Disease Control and Prevention (CDC) estimates that a significant portion of the population is affected by sinusitis. Approximately 28.9 million adults in the United States, or 11.6%, receive a diagnosis of sinusitis.
Common Causes of Chronic Sinusitis
Several factors can contribute to the development of chronic sinusitis:
-
Blockage Preventing Sinus Drainage: Effective sinus drainage is essential for maintaining healthy sinuses. Blockages that impede this drainage are a primary cause of chronic sinusitis. These blockages can result from:
- Facial or nasal injuries: Trauma to the face or nose can disrupt sinus drainage pathways.
- Chronic infections: Persistent infections can lead to inflammation and blockage.
- Nasal polyps: As mentioned earlier, nasal polyps can obstruct sinus openings.
- Tumors: In rare cases, tumors can cause blockage.
- Deviated septum: A deviated septum can also increase the risk of chronic sinusitis by narrowing nasal passages and affecting sinus drainage.
-
Biofilms: Biofilms are colonies of bacteria that form a protective, thick film, similar to dental plaque. These biofilms are notoriously difficult to eradicate. They can establish themselves in the sinuses and contribute to chronic inflammation. Treatments that cleanse the sinuses, such as surgery or nasal irrigation, may be necessary to address biofilms.
-
Unusual Infections: While many sinus infections clear up with standard antibiotics, some infections, such as antibiotic-resistant bacterial infections or fungal infections, do not respond to typical treatments. These infections can become chronic and contribute to chronic sinusitis.
-
Exposure to Allergens and Irritants: Individuals with asthma and allergies have a higher predisposition to chronic sinusitis. These conditions can increase inflammation and pressure in the sinuses and nasal passages. Common triggers include nasal allergens, secondhand smoke, air pollution, and dust particles.
-
Immune System Issues: A weakened immune system makes it harder for the body to combat inflammation and infections. Conditions and disorders that compromise the immune system can increase susceptibility to chronic sinusitis. Cystic fibrosis and HIV are examples of conditions that can increase the risk.

Treatment Options for Nasal Obstruction and Chronic Sinusitis
Seeking professional medical evaluation is crucial for both nasal obstruction and chronic sinusitis to receive an accurate diagnosis and appropriate treatment plan.
Nasal Obstruction Treatment Options
ENT doctors commonly employ various medical and surgical approaches to treat nasal obstruction. Initial treatment often focuses on addressing reversible causes of nasal swelling, such as underlying allergies. Nasal steroid sprays are frequently prescribed to reduce inflammation in the turbinates and nasal passages.
For nasal obstruction caused by enlarged adenoids, surgical removal of the adenoids (adenoidectomy) may be recommended. This is typically an outpatient procedure.
If medications fail to improve turbinate hypertrophy, surgery to reduce the size of the turbinates may be considered. Modern surgical techniques include using small tissue-shaving devices or radiofrequency energy to shrink turbinates.
Balloon sinuplasty is another minimally invasive endoscopic procedure that ENT doctors may utilize to treat nasal obstruction. This procedure involves inserting a small catheter with a balloon into the nasal cavity. Inflating the balloon helps to drain and clear blocked sinuses and reduce inflammation. Balloon sinuplasty is often performed as an outpatient procedure.
The Vivaer Nasal Airway Remodeling procedure is another treatment option available for both nasal obstruction and chronic sinusitis.
Chronic Sinusitis Treatment Options
Because chronic sinusitis is not typically caused by bacterial infections, antibiotics are generally ineffective. Treatment strategies for chronic sinusitis focus on managing inflammation, improving drainage, and addressing underlying contributing factors. Common treatment approaches include:
- Intranasal corticosteroid sprays: These sprays help to reduce inflammation within the sinuses.
- Avoiding triggers: Identifying and avoiding environmental factors and allergens that exacerbate symptoms is crucial.
- Antihistamines: Topical antihistamine sprays or oral antihistamine pills can help manage allergy-related symptoms.
- Antifungal medications: If a fungal infection is suspected, antifungal medications may be prescribed.
- Surgery: In cases of structural problems like a deviated nasal septum, surgery may be necessary to improve sinus drainage.
- Leukotriene antagonists: These medications can help relieve pain and inflammation.
- Treating underlying conditions: Managing conditions like asthma and allergies is essential for controlling chronic sinusitis.
