Causes of Seafood Allergy

Seafood allergies are caused when the immune system tends to overreact. The immune system mistakes any certain protein present in seafood as harmful. This can then lead to the production of antibodies in a severe reaction by the immune system. Thus, whenever a person is in contact with an allergen the immune system releases histamine which causes the symptoms of allergy.

The only way to avoid seafood allergies is to avoid seafood altogether. You should also avoid products that even contain seafood in small quantities. Because even trace amounts can lead to major health complications.

  • Be extremely cautious whenever you are dining out
  • If you are doing grocery, make sure to read the labels properly to check for any trace amount of seafood in a food product.
  • Maintain a safe distance from seafood. Because in some scenarios even touching or inhaling can lead to severe results.

Diagnosis

Your primary healthcare advisor will ask you questions about the symptoms. After that, they might perform a physical exam to rule out any other medical complications.

Given below are the tests that are commonly recommended:

Skin Test

In this test, the skin is pricked and is then exposed to the proteins found in shellfish. In case a person has a seafood allergy then they might develop skin lesions on the exposed surfaces.

Blood Test

This blood test is known as the allergen-specific IgE antibody test. It is also known as the radioallergosorbent test. In this test, the immune system response to the production of IgE is measured.

Treatment of Seafood Allergy | When to Consult a Doctor
