Unfortunately asthma is a chronic condition and anyone with asthma may develop symptoms at any time, from childhood to old age. Asthma symptoms frequently improve or disappear during adolescent or in adulthood. However, they can re-emerge at any point in life.
Asthma is best treated with constant asthma medication. Even when feeling well patients should continue taking their medicine. Long term treatment reduces frequency and severity of asthma attacks/ asthma symptoms.
