Asthma in adults often is a lifelong condition. With treatment, symptoms can be controlled. They can be infrequent or very mild.
In about half of asthmatic children, the asthma goes away on its own. Or it becomes less severe over time. However, it often reappears later in life.
Asthma episodes can go away on their own or with the help of asthma medications. Attacks vary in frequency and severity. It is often dependent on what triggers the attack.
