What happens if your allergic to shell fish?

An allergic reaction to shellfish, also known as shellfish allergy, occurs when the body's immune system overreacts to proteins found in shellfish, such as shrimp, crab, lobster, and clams. When someone with a shellfish allergy consumes shellfish or comes into contact with it, their immune system mistakenly identifies the shellfish proteins as harmful and releases chemicals, including histamine, which trigger a range of allergic symptoms.

Some common symptoms of a shellfish allergy include:

- Hives: Itchy, red raised bumps on the skin

- Swelling: Particularly in the face, lips, tongue, throat, or other parts of the body

- Difficulty breathing: Wheezing, shortness of breath, or tightness in the chest

- Nausea and vomiting

- Abdominal pain

- Diarrhea

- Dizziness and lightheadedness

- Anaphylaxis: A severe, life-threatening allergic reaction characterized by a drop in blood pressure, rapid heart rate, difficulty breathing, and potential loss of consciousness.

The severity of a shellfish allergy can vary from person to person. Some individuals may experience mild symptoms, while others may have more severe reactions, including anaphylaxis. In the event of a severe allergic reaction, it's crucial to seek immediate medical attention.

If you suspect that you or someone you know may have a shellfish allergy, it's essential to consult with an allergist for proper diagnosis and management. The allergist can conduct allergy skin tests or blood tests to determine the specific shellfish allergen causing the reaction and provide appropriate treatment options.

To prevent allergic reactions, individuals with shellfish allergy must strictly avoid consuming shellfish or products containing shellfish ingredients. Additionally, it is important to be cautious about cross-contamination and to inform restaurants or food establishments about any food allergies before placing orders.
