Understanding Nasal Flaring

What is Nasal Flaring?

Nasal flaring refers to the outward movement of the nostrils during inhalation.

It’s a physiological response that occurs when the body needs to take in more air.

When you inhale, your diaphragm contracts and pulls air into your lungs. The muscles surrounding your nostrils then widen to allow for greater airflow.

This increased airflow is often necessary during periods of increased physical activity, stress, or when the nasal passages are blocked.

There are several reasons why nasal flaring might occur:

• Exercise

• Respiratory illnesses: Conditions like colds, allergies, or sinusitis can cause inflammation and swelling in the nasal passages, making it harder to breathe through the nose. Nasal flaring helps compensate for this restricted airflow.

• Asthma:**

During an asthma attack, the airways narrow, leading to difficulty breathing. Nasal flaring can be a symptom of increased respiratory effort.

• Sleep apnea:**

This disorder causes pauses in breathing during sleep. Nasal flaring may occur during these periods as the body struggles to get enough oxygen.

• Congenital nasal defects:**

Some individuals may be born with anatomical variations in their nose that predispose them to nasal flaring.

It’s important to note that mild nasal flaring during exercise is normal and nothing to worry about.

However, if you experience frequent or persistent nasal flaring accompanied by other symptoms like wheezing, coughing, difficulty breathing, or sleep disturbances, it’s essential to consult a medical professional.

Causes of Nasal Flaring

Nasal flaring, or widening of the nostrils during breathing, is a common physiological response that often occurs when we need to increase airflow through the nose.

During normal breathing, air enters the body through the nose and travels down the trachea, or windpipe, into the lungs. When nasal flaring happens, it’s because the muscles around the nostrils contract, widening them and allowing more air to enter.

This is a natural reflex that occurs in situations where increased airflow is needed. For example, during exercise, when we are asleep, or when breathing is labored due to illness or obstruction.

Nasal flaring can also occur in infants and young children, who may flare their nostrils more prominently as they learn to control their breathing.

While nasal flaring is generally normal and harmless, it can sometimes be a sign of an underlying medical condition.

Here are some potential causes of nasal flaring:

• Upper respiratory infections (URIs): Colds, flu, and sinusitis can cause inflammation in the nose, making it difficult to breathe through the nose normally. This can lead to nasal flaring as the body tries to compensate for the obstructed airflow.
• Allergies: Allergic rhinitis, or hay fever, can also cause nasal congestion and inflammation, triggering nasal flaring.
• Nasal polyps: These are soft, noncancerous growths in the nose that can block airflow.
• Deviated septum: This is a condition where the wall that separates the two nostrils (the septum) is crooked or off-center, causing one nostril to be blocked.
• Foreign objects in the nose: In children, inserting objects like small toys or beads into the nose can cause obstruction and nasal flaring.

If you notice persistent or excessive nasal flaring, it’s important to consult a doctor to rule out any underlying medical conditions.

They will likely examine your nose and throat, ask about your symptoms, and may recommend additional tests, such as allergy testing or an X-ray of the sinuses, to determine the cause.

Depending on the underlying cause, treatment options may include medication to reduce inflammation, decongestants, nasal irrigation, surgery, or allergen avoidance.

When to Worry About Nasal Flaring

Factors that Indicate a Problem

Nasal flaring, or the widening of nostrils during breathing, is a common occurrence and usually nothing to worry about. It often happens during periods of exertion, when you’re asleep, or in certain medical conditions.

However, persistent nasal flaring, particularly if accompanied by other symptoms, may indicate an underlying problem requiring medical attention.

Here are some factors that can signal a need for concern:

• **Constant Nasal Flaring:** If your nostrils flare noticeably even during normal breathing, especially when you’re relaxed and not exerting yourself, this could suggest a blockage or narrowing of the nasal airways.

•

Associated Symptoms: Pay attention to other symptoms alongside persistent nasal flaring. These might include:

• Difficulty breathing
• Loud snoring
• Excessive daytime sleepiness
• Mouth breathing, especially during sleep
• Nasal congestion or stuffiness
• Nosebleeds
• Facial pain or pressure

• **Age:** While nasal flaring in infants is usually normal, persistent flaring in older children and adults warrants evaluation.

•

Medical History: Certain medical conditions, such as asthma, allergies, or a deviated septum, can contribute to nasal flaring.

If you notice any of these signs, it’s best to consult with a healthcare professional. They can determine the underlying cause and recommend appropriate treatment options.

Diagnosis and Treatment

Medical Evaluation

Diagnosis and treatment of any medical condition, including those related to nasal flaring, involve a systematic process that begins with a thorough medical evaluation.

Medical Evaluation:

1. History Taking:** A detailed medical history is crucial. This includes questions about the duration, severity, and frequency of nasal flaring, associated symptoms (like snoring, difficulty breathing, wheezing), family history of respiratory conditions, and any recent illnesses or exposures.
2. Physical Examination: The physician will examine the nose and airways. They will look for signs of congestion, inflammation, deformities, or other structural issues that might be contributing to nasal flaring.
3. Respiratory Assessment:** Lung sounds will be listened to with a stethoscope to check for wheezing, crackles, or other abnormalities. The doctor may also assess breathing rate and effort.

Further Investigations:

• Imaging Studies: X-rays of the sinuses or chest might be ordered to rule out conditions like sinusitis, pneumonia, or other abnormalities. In some cases, a computed tomography (CT) scan may be necessary for a more detailed view of nasal structures.
• Allergy Testing:** If allergies are suspected as a cause of nasal flaring, allergy tests (skin prick or blood tests) can help identify specific allergens.
• Sleep Study: For individuals experiencing nasal flaring during sleep (snoring), a sleep study might be recommended to assess for sleep apnea.

Diagnosis and Treatment will vary depending on the underlying cause of the nasal flaring.

Possible Causes:

• Upper respiratory infections: These are common causes of temporary nasal flaring, as congestion occurs due to inflammation.
• Allergies:** Allergic rhinitis can lead to nasal inflammation and increased breathing through the nose.
• Asthma:**
• Structural Abnormalities:
• Enlarged adenoids:
• **Nasal valve collapse: **

Potential Treatment Options

Nasal flaring, a widening of the nostrils during breathing, can be a normal physiological response to increased respiratory effort. It often occurs in infants and young children, especially when they are active or have a stuffy nose.

However, persistent or excessive nasal flaring, particularly in older children or adults, *may* indicate an underlying medical condition requiring further investigation.

**Possible Causes of Abnormal Nasal Flaring:**

• Obstructive sleep apnea (OSA): This common sleep disorder involves repeated pauses in breathing during sleep. Nasal flaring can be a symptom, along with snoring and daytime sleepiness.

• Upper respiratory infections (URIs): Common colds, the flu, and sinusitis can cause nasal congestion and inflammation, leading to increased effort when breathing and, consequently, nasal flaring.

• Deviated septum: A crooked nasal septum can obstruct airflow, forcing the nostrils to widen during breathing.

• Nasal polyps: These benign growths in the nasal lining can block nasal passages, causing difficulty breathing and flaring.

• Foreign object in the nose: A foreign object lodged in the nostril can cause obstruction and lead to nasal flaring.

**Diagnosis:**

If you notice persistent or excessive nasal flaring, particularly in combination with other symptoms like snoring, difficulty breathing, or daytime sleepiness, it’s important to consult a doctor. They may perform a physical examination of the nose and throat, order imaging studies (such as an X-ray or CT scan), or recommend a sleep study to rule out OSA.

**Treatment Options:**

Treatment for nasal flaring depends on the underlying cause.
For example:

• URIs are typically treated with symptom management, such as decongestants and pain relievers.

• Deviated septum may require surgery to straighten the nasal cartilage.

• Nasal polyps can often be removed surgically or through other procedures.

• If a foreign object is lodged in the nose, it will need to be carefully removed by a medical professional.

• OSA treatment typically involves lifestyle changes (weight loss, avoiding alcohol before bed) and/or continuous positive airway pressure (CPAP) therapy.
