Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to recurrent symptoms. These symptoms often include wheezing, coughing, chest tightness, and shortness of breath. Many individuals, especially parents of children with the condition, often wonder if it is possible to “outgrow” asthma as they get older.
Understanding Asthma Remission
The concept of “outgrowing asthma” is often referred to as asthma remission, where symptoms disappear over time. While a significant percentage of children diagnosed with asthma do experience a period of remission by early adulthood, this does not always mean the underlying airway hypersensitivity has completely vanished. Studies have estimated that anywhere from 15% to 64% of children with asthma may achieve remission by early adulthood, with rates varying depending on the specific population studied. Remission most commonly occurs between the ages of 14 and 21 years.
It is important to differentiate between transient childhood asthma, where symptoms resolve and may not return, and more persistent forms. Even when symptoms are absent, the airways might still react to certain triggers, indicating that the predisposition to asthma remains. For individuals with well-preserved lung function in childhood, such as those with a forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio of 90% or greater, over half of boys (54%) and two-thirds of girls (70%) were in remission by early adulthood. However, fewer than 10% of children with a baseline FEV1/FVC ratio less than 80% experienced remission.
Factors Influencing Asthma Persistence
Several factors increase the likelihood of asthma persisting into adulthood rather than going into remission. Asthma that begins very early in life or presents with greater severity often has a higher chance of continuing. Allergic asthma, also known as atopic asthma, which is linked to sensitivities to common allergens, is more likely to persist compared to non-allergic forms. The presence of other atopic conditions, such as eczema or allergic rhinitis, can also indicate a higher risk of persistent asthma.
A strong family history of asthma or allergies in close relatives can predispose an individual to asthma that continues beyond childhood. Poor baseline lung function during childhood is another significant predictor. Continued exposure to environmental triggers, including tobacco smoke (especially maternal smoking during pregnancy), allergens, or air pollutants, can also contribute to the persistence of asthma symptoms.
Living with Adult Asthma
For individuals whose asthma does not go into remission or who experience a relapse in adulthood, ongoing management is important. Regular medical check-ups with a healthcare provider are advised, even if symptoms are mild or intermittent, to monitor lung function and adjust treatment plans as needed. Adherence to prescribed treatment regimens, including inhaled corticosteroids, is recommended even during symptom-free periods to maintain control over airway inflammation.
Recognizing and avoiding personal asthma triggers, such as allergens, irritants, or exercise patterns that induce symptoms, can help prevent exacerbations. Developing and maintaining a personalized asthma action plan, created in consultation with a doctor, provides clear instructions on how to manage symptoms, adjust medication, and identify when to seek emergency care. Even if symptoms disappear for a time, vigilance remains important due to the possibility of recurrence, particularly with specific environmental changes, new exposures, or significant life events.
