How is a blocked nose treated?

In this article below, experienced consultant ENT surgeon, Mr Pavol Surda, provides a comprehensive insight into what causes a blocked nose, and how this can be effectively managed and treated. 

What is a blocked nose?

A blocked nose, or nasal congestion, is a common condition where the nasal passages become swollen or inflamed, making it difficult to breathe through the nose. This uncomfortable sensation can occur for various reasons, ranging from colds and allergies to sinus infections or even structural issues like a deviated septum. Understanding the underlying cause of nasal congestion is key to finding effective relief.

Causes

One of the most frequent causes of a blocked nose is the common cold. Viruses irritate the nasal lining, causing inflammation and an increase in mucus production, leading to congestion. Allergies, particularly to pollen, dust, or pet dander, can also trigger a similar reaction.

When an allergen is inhaled, the body’s immune system responds by releasing histamine, which inflames the nasal passages and leads to a blocked or runny nose. In cases of seasonal allergies, the condition is known as allergic rhinitis.

Sinus infections, or sinusitis, are another common cause of a blocked nose. Sinusitis occurs when the sinuses, which are air-filled spaces around the nose, become inflamed, typically due to an infection.

The swelling blocks the normal flow of mucus, causing pressure and congestion. Sinusitis can be acute, lasting a few weeks, or chronic, lasting several months, and may require different types of treatment depending on the cause.

Structural issues within the nose can also contribute to chronic nasal congestion. A deviated septum, where the nasal septum (the cartilage that divides the nostrils) is off-center, can make one or both sides of the nose feel blocked. Nasal polyps, small growths inside the nasal passages, can also obstruct airflow and require medical attention.

Treatment

Treating a blocked nose depends on its cause. Over-the-counter decongestants or saline nasal sprays can provide short-term relief by reducing swelling. If allergies are the culprit, antihistamines or nasal corticosteroids can help manage symptoms. For more chronic conditions like sinusitis or a deviated septum, medical interventions such as antibiotics, steroid treatments, or even surgery may be necessary.

If nasal congestion persists for more than a couple of weeks, or if it’s accompanied by other symptoms like facial pain or fever, it’s important to consult a healthcare provider for a proper diagnosis and treatment plan.
