Asthma is a chronic condition that affects your ability to get enough airflow into and out of your lungs. It can cause swelling and mucus to build up in your airways.
If you have asthma, you likely experience times when the air movement in your lungs feels more constricted. This can lead to breathing difficulties. Asthma attacks occur when your symptoms develop rapidly or become severe.
Whether you live with mild, moderate, or severe asthma, the more you know about your condition, the easier it will be to manage it. Take this self-assessment to find out how much you know about living with and treating asthma.
