Shellfish is one of the most common allergens in children. Shellfish allergies can be severe, and even life-threatening. It is essential for parents to know the symptoms of a shellfish allergy and how to manage them.
This article will outline the causes, symptoms, and treatment options for a shellfish allergy.
What is a shellfish allergy?
A shellfish allergy is a reaction of the immune system to a protein found in shellfish. The two types of shellfish that people are most commonly allergic to are crustaceans and mollusks. Examples of crustaceans include shrimp, crab, and lobster.
Examples of mollusks include clams, mussels, and oysters.
Causes of a shellfish allergy
The protein in shellfish that causes an allergic reaction is called tropomyosin. When the immune system detects this protein, it produces antibodies that release histamine, causing an allergic reaction.
Shellfish allergies are most common in adults, but they can also develop in children. If your family has a history of allergies or asthma, your child may be more likely to develop a shellfish allergy.
Symptoms of a shellfish allergy
The symptoms of a shellfish allergy can range from mild to severe. It is important to recognize the symptoms early and seek medical attention if necessary.
Mild symptoms of a shellfish allergy may include:.
- Hives or rash
- Itching or tingling in the mouth
- Swelling of the lips, tongue, or throat
- Nausea or vomiting
- Stomach pain
Severe symptoms of a shellfish allergy may include:.
- Difficulty breathing
- Swelling of the face, eyes, or tongue
- Weakness or dizziness
- Fainting
- Loss of consciousness
If your child experiences any of these severe symptoms after eating shellfish, seek emergency medical attention immediately.
