Nasal breathing is a vital function of human health. When airflow through the nose is
blocked—often referred to as nasal obstruction or congestion—it can significantly affect
quality of life.
Difficulty breathing through the nose can interfere with sleep, exercise, concentration,
and even relationships. Many patients also notice problems with smell, taste, speaking
clearly, and overall comfort during breathing.
Nasal obstruction is one of the most common reasons people seek care from an ear, nose,
and throat specialist.
What Causes Nasal Obstruction?
Nasal congestion occurs when airflow through the nose is restricted. This usually
happens because the lining of the nose becomes inflamed or swollen, rather than
because of mucus alone.
Many different factors can irritate the nose and cause swelling, including:
Infections
● Colds or viral infections
● Influenza
● Acute or chronic sinusitis
Structural conditions
● Deviated septum
● Enlarged adenoids or tonsils
● Nasal polyps
● Tumors (rare)
Allergic or environmental triggers
● Allergies
● Cigarette smoke
● Dry air
● Cold temperatures
● Spicy foods
Other contributing factors
● Hormonal changes
● Thyroid disorders
● Certain medications
● Stress
● Headaches
Because many conditions can contribute to nasal obstruction, identifying the underlying
cause is important before choosing treatment.
Symptoms of Nasal Obstruction
Common symptoms include:
● Chronic nasal congestion or stuffiness
● Persistent nasal blockage
● Difficulty breathing through the nose
● Difficulty sleeping or snoring
● Daytime fatigue
● Trouble getting enough air during exercise
● Reduced sense of smell or taste
● Mouth breathing
Treatment Options for Nasal Congestion
Treatment depends on the cause of the obstruction and may include medications, nasal
rinses, or procedures to improve airflow.
Decongestants
Decongestants can be helpful for short-term relief of occasional congestion. These
medications work by constricting blood vessels in the nasal lining, reducing swelling and
allowing more airflow.
They are available as oral medications or topical nasal sprays.
However, decongestants may cause side effects such as:
● Rapid heart rate
● Elevated blood pressure
● Jitteriness
● Difficulty sleeping
Patients with heart disease or a history of heart attack should avoid these medications.
Topical nasal decongestant sprays can also become habit-forming if used for more than a
few days. Prolonged use may lead to worsening congestion once the medication is stopped.
Antihistamines
Antihistamines help reduce swelling and mucus production when congestion is related to
allergies.
Common antihistamines include:
● Benadryl (diphenhydramine)
● Xyzal (levocetirizine)
● Zyrtec (cetirizine)
● Allegra (fexofenadine)
● Claritin (loratadine)
The newer antihistamines listed above typically cause less sedation than Benadryl, which
is why we often avoid Benadryl, particularly in older patients.
Topical Nasal Steroids
Nasal steroid sprays are commonly used to treat allergic or inflammatory nasal
congestion. These medications reduce inflammation within the nasal passages.
Examples include:
● Flonase (fluticasone)
● Nasonex (mometasone)
These sprays can sometimes cause dryness in the nose. Patients who are prone to
nosebleeds may need alternative treatment options.
Sinus Rinses
Saline sinus rinses are a natural and effective way to reduce swelling in the nasal
passages.
These rinses typically use distilled water mixed with saline packets. Hypertonic saline
(higher salt concentration) may provide additional benefit, although some patients notice a
mild burning sensation.
In certain situations, medications may be added to the rinse solution to improve
effectiveness.
Anti-Leukotriene Medications
Anti-leukotriene medications were originally developed for asthma but are also used for
allergic nasal congestion.
The most commonly prescribed medication in this class is Singulair (montelukast).
These medications may be particularly helpful when nasal polyps are present.
Some studies suggest that a combination of Flonase and Singulair may also help reduce
snoring.

Procedures for Nasal Obstruction
When medications are not sufficient, several procedures can improve airflow through the
nose.
Vivaer or Rhinaer
These minimally invasive procedures use low-temperature radiofrequency energy to
gently reshape the tissues inside the nose without changing the outward appearance.
They can often be performed in the office and may provide long-lasting improvement in
nasal breathing.
Septoplasty
Septoplasty is a surgical procedure that straightens the nasal septum, the divider
between the two nasal passages.
The surgery is performed in an outpatient surgical center, meaning there is no overnight
hospital stay. Most patients recover within about one week.
Turbinate Reduction
Turbinates are normal structures inside the nose that help humidify and filter inhaled air.
In some individuals, the turbinates become enlarged due to allergic or non-allergic
inflammation.
Reducing the size of the inferior turbinates can improve airflow through the nose.
This procedure is typically performed in an outpatient surgical center, and recovery is
usually less than one week. If the underlying cause of inflammation is not addressed,
turbinate swelling may recur.
Nasal Valve Surgery
The nasal valve is the narrowest part of the nasal airway near the front of the nose. If this
area collapses or narrows, airflow can be significantly restricted.
Surgical procedures can widen this area to improve nasal breathing and airflow.
Adenoid Removal (Primarily in Children)
In children, enlarged adenoids can block the nasal airway and lead to chronic mouth
breathing.
Persistent mouth breathing during childhood can affect normal facial development,
sometimes resulting in a narrower airway later in life.
This may contribute to breathing and sleep problems during both childhood and adulthood.
When to Seek Evaluation
You may benefit from evaluation if you experience:
● Persistent nasal congestion
● Difficulty breathing through the nose
● Chronic mouth breathing
● Snoring or poor sleep
● Reduced sense of smell
● Fatigue related to poor sleep quality
A comprehensive evaluation can help determine the cause of nasal obstruction and
identify the most appropriate treatment options.
