Asthma is a lung disease that makes it difficult to breathe. You can prevent asthma attacks by carefully changing your environment and avoiding triggers. Your doctor may also prescribe medicine that can help.
What causes asthma?
Asthma is hereditary, so if one or both of your parents had asthma, it’s likely you’ll have asthma too. In addition to genetics, allergies, illness, smoking, pets, cold air, stress or even exercise can trigger asthma.
What are symptoms of asthma?
Symptoms include shortness of breath, wheezing, coughing or a feeling of tightness in the chest.
The lungs react in two different ways:
- Muscle spasms make breathing difficult
- Airways get narrow because the lining of the lungs is inflamed
