No. Outgrowing asthma is a slightly controversial topic; while some adults who had asthma as a child do not have symptoms as an adult, objective measurements of lung function often find problems in these individuals. It is not clear if there is truly a lessening of the disease, a decrease in activity, or tolerance (or some combination of all three) that leads to the phenomina.
Not. Necessarily . The current thinking is that asthma changes over your lifetime.
Depends. This is a tricky issue with confusion over labels in infancy that are imprecise. Many kids with wheezing issues as infants & toddlers come by them with infection triggered events that respond to asthma medications. Some use the asthma label for these kids without further testing. More than half will quit having wheezing events after age 5.So your answer depends on how you use the label.
Sometimes. Many physicians who treat asthma avoid calling a child an asthmatic patient until they are about 5 years old. This is because viral infections may cause wheezing in younger children. Viral respiratory infections will not usually cause wheezing in adults or older children unless they have an underlying asthma problem. Many kids who wheeze before age 5 often appear to outgrow their "asthma".
