Q

Describe the pathophysiology of asthma

A
  1. IgE mediated response to an allergen
  2. Release of inflammatory mediators (e.g., histamine, leukotrienes, prostaglandins)
  3. This causes bronchospasm, triggering an asthma attack
  4. Excess mucus plugs the airway. Along with increased airway tone and hyper-responsiveness, the airway narrows

Q

Why is it important to optimise omega 3:6 ratio in asthma?

A

An inflammatory omega 6:3 profile causes increased PGE2 synthesis, which increases IgE, atopy and inflammation.
