Nasal Congestion - Causes and Ways to Relieve It

What Is Nasal Congestion?

Nasal congestion is the obstructed or restricted breathing through the nose due to the inflammation of blood vessels lining the tissues of the nose. It may or may not be accompanied by discharge from the nose. Nasal congestion can be irritating in the case of adults and older children. It needs to be considered serious when it affects breastfed babies as it interferes with feeding and disturbs the sleep in children.

What Causes Nasal Congestion?

Nasal congestion can be caused by various conditions like infections, allergies, and sometimes irritants like pollution from cars and tobacco smoke. Also, any growth inside the nasal cavity can cause breathing obstruction.

Causes of nasal congestion include:

  • Common Cold- A common cold is a viral infection that affects the upper respiratory system, and the patients will have runny noses, sneezing, and sore throat other than stuffy noses.

  • Allergies- Allergies occur when our body’s immune system reacts to a foreign particle entering our system. This reaction ranges from mild to moderate. The most commonly seen allergens causing nasal congestion are pollen, dust mites, and pet dander.

  • Acute Sinusitis- It is a condition in which the sinuses are inflamed and swollen and cause blockage to drainage of mucus resulting in mucus buildup. In this case, along with nasal congestion, the patient will have a runny nose and pain around the eyes, nose, cheek, or forehead region.

  • Chronic Sinusitis- It is similar to acute sinusitis but persists for over a period of more than three months.

  • Nasal Polyps- This is a tear-shaped non-cancerous growth inside the nasal cavity that can obstruct the air passage, and hence the patient can have nasal congestion. Nasal polyps are formed as a result of chronic inflammation due to conditions like asthma, allergies, immune disorders, or recurring infections. This is commonly seen in adults, and surgery is indicated in such cases, depending on the severity.

  • Deviated Nasal Septum- It is a condition in which the nasal septum that separates the two chambers of the nasal cavity is deviated to one side, making the air passage of one side narrow, and such patients might face difficulty in breathing. The treatment for such a condition is the surgical correction of the defect.

  • Enlarged Adenoids - Adenoids are the lymph tissues that are present between the nose and the back of the throat. Adenoids are enlarged in cases of infection and usually return back to their normal size when the infection subsides, but in some cases, the enlarged adenoids remain the same size post-infection. In such cases, it can block the airway, and surgical removal of the adenoids is indicated.

  • Influenza (flu) - Influenza is a viral infection that affects the respiratory system, including the nose, throat, and lungs. Other than nasal congestion, the flu can show other symptoms such as fever, chills, sore throat, runny nose, and cough.

  • Nonallergic Rhinitis- It is a condition in which the patient has nasal congestion, runny nose, and sneezing without any known cause.

  • Eosinophilic Granulomatosis with Polyangiitis (EGPA) -Also known as Churg-Strauss syndrome, in which there is inflammation of blood vessels. Other symptoms of this disease include adult-onset asthma, nasal allergies, sinus problems, rash, gastrointestinal bleeding, and numbness of hands and feet. The treatment advised is steroidal medicines to limit the symptoms.

Other causes include:

  • Medication for hypertension, erectile dysfunction, depression, seizures, etc.

  • Overuse of decongestant nasal spray.

  • Changes in temperature and humidity.

  • Hormonal changes.

  • Foreign body in the nose.

  • Tobacco smoke.

  • Pregnancy.

How to Relieve Nasal Congestion?

Nasal congestion can greatly affect your daily routines and can be irritating sometimes. Here are some ways to quickly relieve nasal congestion:

  • Use of Humidifier:

A humidifier is primarily an electric device that turns the water into moisture which in turn increases the humidity of the air. It is often seen that this humidity in the air can soothe irritated tissue and decrease the inflammation of the blood vessels. It is an easy method to reduce sinus pain and relieve nasal congestion. In some conditions use of a heated humidifier can help the discharge of congested mucus and thus relieve the symptom.

  • Shower:

Have you ever noticed that taking a warm shower would help you breathe better when you have a stuffy nose?

Yes, the reason is that taking a warm shower would reduce the inflammation and thin out the mucus.

  • Saline Nasal Spray:

What the saline nasal spray does is, introduce moisture into the breathed air and thus provide comfort while breathing.

Take medical advice before taking decongestant nasal sprays.

  • Stay Hydrated:

Stay hydrated if you suspect the flu or cold. Drinking optimum level water will lead to thinning of the mucus and thus can be easily pushed out, thus less mucus, less inflammation and better breathing.

  • Warm Compress:

To make a warm compress, soak a towel in warm water and squeeze out the excess water from it; place this towel over the nose and the forehead. The warmth from this will comfort pain in the sinus and reduce the inflammation in the nostrils.

  • Medications:

Over-the-counter medicines that can be used for nasal congestion like antihistamines, decongestants, or allergy medications.

Consult a doctor if the symptoms do not relieve after taking medicines for more than three days.

  • Proper Positioning of Head:

It is worsened when lying down, so keep an upright position or keep your head in an elevated position while sleeping to reduce the discomfort.

When to See a Doctor?

Consider consulting a doctor for the following reasons:

  • If the congestion persists for more than ten days.

  • If it is accompanied by a high fever and chills for more than three days.

  • When there is green discharge or foul-smelling discharge along with nasal congestion.

  • When there is pain around the eyes, cheek, and forehead which persists even after taking medications.

  • Severe throat pain.
