Can it change?

Food allergies such as cow's milk allergy and egg allergy often improve as children build tolerance. The outcome of shellfish allergy varies from person to person. Whether it has changed needs to be judged based on age, how severe past reactions were, trends in test results, and follow-up assessments.

Two extremes parents often fall into

  • Being too optimistic: trying foods on your own because "they'll grow out of it" can carry risks
  • Avoiding too much: cutting out all shellfish and related foods affects nutrition and social life

A workable path

Go to follow-up visits on schedule and tell the doctor about your child's eating and symptoms. Have the relevant tests repeated as the doctor advises. If conditions allow, re-introduction should be done in a medical setting according to guidelines, with emergency preparations in place. During strict daily avoidance, pay attention to nutritional substitutes and emotional support, so your child understands their situation and learns to speak up about it.
