Lesson Summary
You will learn to describe the symptoms of asthma, and some of the risk factors that can increase the chance of having asthma.
Key Notes
- Asthma is a common non-infectious disease that can cause breathing difficulties.
- During an asthma attack, the breathing (bronchial) tubes narrow.

- Symptoms of asthma can be treated using medication taken using an inhaler.
- Risk factors for asthma include air pollution, smoking, low birth weight, having an allergy, and family history.
