🥜 Childhood Allergy Outgrowing Likelihood Simulator

Milk and Egg Allergy Usually Resolve With Age

Most kids age out of milk and egg allergy well before adulthood.

• ~80%: Outgrown by age 16 (placeholder estimate)
• 5–10 yrs: Typical resolution age (placeholder estimate)
• Common: Baked-form tolerance (placeholder estimate)
• Low: Relapse risk (placeholder estimate)

Why milk/egg allergy fades

Placeholder: immune tolerance to these proteins often develops through childhood.

Peanut and Tree Nut Allergy Persist More Often

Only a minority of children outgrow peanut or tree nut allergy.

• ~20%: Outgrown by age 16 (placeholder estimate)
• Moderate: Cross-reactivity (placeholder estimate)
• Elevated: Anaphylaxis risk (placeholder estimate)
• Emerging option: Oral immunotherapy (placeholder estimate)

Why nut allergies linger

Placeholder: nut allergens trigger more durable immune sensitization.

Shellfish Allergy Is Rarely Outgrown

Shellfish allergy most often persists into and through adulthood.

• ~8%: Outgrown by age 16 (placeholder estimate)
• Frequent: Adult-onset cases (placeholder estimate)
• Stable/rising: Severity trend (placeholder estimate)
• Lifelong (typical): Avoidance duration (placeholder estimate)

Why shellfish allergy sticks around

Placeholder: shellfish proteins tend to sustain long-lived immune memory.

Falling IgE Levels Predict Outgrowing

A downward specific-IgE trend over years is the best early signal.

• Multi-year: IgE slope watched (placeholder estimate)
• Shrinking wheal: Skin test correlate (placeholder estimate)
• Moderate-high: Predictive value (placeholder estimate)
• sIgE / SPT: Test type (placeholder estimate)

Reading the IgE trend line

Placeholder: a steadily declining curve supports eventual tolerance.

Scheduled Re-Testing Guides Diet Decisions

Periodic allergy re-testing catches the point a child outgrows it.

• 6–12 mo: Young children (placeholder estimate)
• 1–2 yr: School-age (placeholder estimate)
• 2–3 yr: Teens (placeholder estimate)
• sIgE + oral challenge: Method (placeholder estimate)

Why re-testing matters

Placeholder: regular checks avoid unnecessary long-term avoidance.

Placeholder: always confirm resolution with a supervised oral food challenge.
