Asthma and Eczema: Two Sides of the Same Constitution

An allergic constitution often shows different symptoms at different ages. Eczema and asthma may appear one after the other.

Why they appear together

Eczema, allergic rhinitis and asthma are all linked to an allergic constitution. Many people develop eczema in infancy, then develop nose or lower airway symptoms as they grow older. This pattern of one appearing after the other is common in clinical practice. But not all eczema leads to asthma, and the two are not a simple cause-and-effect relationship.

A shared approach to management

  • Skin: moisturise generously, avoid irritants, and use topical treatments as prescribed
  • Airways: use controller medicines regularly, and reduce exposure to allergens and irritants
  • Environment: reduce house dust mite, pollen, smoke and strong smells
  • Follow-up visits: tell the doctor about changes in both skin and breathing symptoms

Do not over-interpret

If your child has eczema, there is no need to be overly anxious, and there is no need to make major dietary restrictions to "prevent asthma". Just keep the follow-up appointments your doctor arranges, and see a doctor promptly for assessment if there is repeated coughing, wheezing or night-time symptoms.
