About Bronchiolitis

What Is Bronchiolitis?

Bronchiolitis is a common condition affecting babies and young children. It is caused by an inflammation of the small airways in the lungs called the bronchioles, which restricts the amount of air able to enter the lungs, making it more difficult for the child to breathe.

Babies at greater risk of developing severe bronchiolitis include premature babies and babies with certain heart or lung conditions.In most cases bronchiolitis is not a severe illness, however, 3% of babies who are under one year of age and have bronchiolitis are admitted to hospital every year in the UK.

What's The Difference Between Bronchitis And Bronchiolitis?

Bronchiolitis should not be confused with bronchitis.

Bronchitis is a condition that affects both adults and children. It occurs when an infection causes the bronchi (the larger airways in the lungs) to become irritated and swollen (inflamed), which causes more mucus production than usual. The body will try to get rid of this extra mucus through coughing.

Bronchiolitis is an inflammation of the bronchioles (the small airways in the lungs), which causes breathing difficulties.

How Common Is Bronchiolitis?

It is estimated that one in three babies in the UK develop bronchiolitis in the first year of their life.The condition is most common in young babies who are three to six months old.

The timing of the bronchiolitis season slightly varies in the UK from year to year but it usually occurs during the winter months, from October to March, when the viruses that can cause bronchiolitis are more common.It is also possible to develop bronchiolitis more than once during the same winter season.
