Asthma in children
Asthma is the most prevalent long-term medical condition among children in the UK, affecting around 1 in 11 children. While asthma can develop at any age, symptoms typically begin in early childhood, often before the age of three.
If your child has asthma, their airways are inflamed and more sensitive than usual. When the airways are irritated, the body reacts in 3 ways:
- The muscles around the airways tighten, making them narrower
- The lining of the airways become inflamed and swollen, making them narrower
- The airways may start to produce more mucus than normal
These reactions make it harder for air to get into and out of the lungs. This causes the symptoms of asthma: coughing, wheezing, shortness of breath and chest tightness. When these symptoms flare up, people sometimes say it’s an asthma attack.
There’s no cure for asthma, but it can usually be controlled easily with the right treatment. Some children will find that their symptoms improve or even disappear as they grow up.
