Overview

Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels. It is also known as nasal blockage, nasal obstruction, blocked nose, runny nose, and stuffy nose.

Pathophysiology

Many people think that a nose gets congested (stuffy) from too much thick mucus. However, in most cases, the nose becomes congested when the tissues lining it become swollen. The swelling is due to inflamed blood vessels.

Diagnosis

X ray

X-rays of the sinuses and chest x-ray

CT

CT scan of sinuses are required in some patients to make the diagnosis.

Natural History

Nasal congestion has many causes and can range from a mild annoyance to a life-threatening condition. The newborn infant is an obligate nose breather and must breathe through the nose. Nasal congestion in an infant in the first few months of life can interfere with nursing and cause life-threatening respiratory distress. Nasal congestion in older children and adolescents is often just an annoyance but can cause other difficulties. Nasal congestion can interfere with the ears, hearing, and speech development. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea. In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia, as well as right-sided heart failure. The problem usually resolves after surgery to remove the adenoids and tonsils.A blocked nose can also cause mild facial and head pain, and a degree of discomfort.
