How do I know if my child's food reaction is mild or serious enough to need emergency care?

A mild reaction typically involves symptoms limited to one area of the body, such as localised hives, itching, or mild stomach pain, without affecting breathing, blood pressure, or the child's overall responsiveness. A serious reaction, or anaphylaxis, involves two or more body systems simultaneously or any single life-threatening feature: difficulty breathing, swelling of the tongue or throat, repeated vomiting, dizziness, fainting, or a child becoming pale and unresponsive. When in doubt, treat as serious. Any breathing difficulty or throat tightness after eating a known or suspected allergen is a medical emergency requiring immediate adrenaline and hospital care.
