asthma a chronic disease

• Who gets asthma?
Asthma tends to run in families, which means that you are more likely to develop asthma if someone in your family already has it. Children with eczema or food allergy are more likely than other children to develop asthma.
Allergy to pollen, house dust mites or pets also increases your chance of developing asthma. Exposure to tobacco smoke, air pollution or other inhaled irritants can also cause asthma symptoms in those with an underlying tendency to asthma.
• At what age does asthma start?
Asthma can start at any age, although about half of all people with asthma have had their first symptoms by the age of 10, and many children with asthma have had their first asthma attack before the age of 6.

• asthma a chronic disease?

Yes. Asthma is a chronic (long-term) disease that causes inflammation and narrowing of the airways. Some degree of inflammation is usually present, even at times when you are unaware of any symptoms.

If your asthma is untreated, you will have repeated attacks of asthma symptoms.

Mild attacks can settle down without treatment, but treatment usually helps them to resolve more quickly. Appropriate treatment can also reduce the risk of further attacks.
