Does asthma get better with age?

My 12-year-old son was recently diagnosed with asthma. I was however reassured that he will get over it as he grows older. Kindly let me know if this is true.

Asthma is often a life-long condition, although asthma in young children sometimes goes away by the time they’re teenagers or adults. Asthma affects everyone differently. What is important is to be regular with your son’s medications and medical consultations.
