Gut Microbiome

Bacterial diversity affects allergy risk

Microbiome Influences

  • Antibiotic use
  • Cesarean births
  • Formula feeding
  • Diet diversity
  • Environmental exposure

Development Process

Stage 1: Sensitization
  • • First exposure to allergen
  • • IgE antibody production

Stage 2: Activation
  • • Re-exposure to allergen
  • • IgE recognition
  • • Chemical release
Stage 3: Symptoms
  • • Allergic reaction
  • • Varying severity
  • • Multiple systems affected

Prevention Strategies

  • • Early introduction of allergenic foods
