There's no cure for asthma. However, it's a highly treatable disease. In fact, some doctors say today's asthma treatments are so effective, many people have near-complete control of their symptoms.
Can asthma be cured completely?
Asthma cannot be cured completely, no, but it can be controlled to the point that the symptoms become negligible. As a chronic and lasting condition, asthma is not curable. It is highly treatable, though, so long as a patient has professional support.
Can asthma be cured at early stage?
No, asthma cannot be cured. Some children with asthma will outgrow it by adulthood. But, for many, asthma is a lifelong condition.
