Shellfish allergy is one of the most common and severe food allergies, affecting approximately 1% of the general population in the United States. It is an immune system reaction to one or more proteins found in shellfish, such as crustaceans (e.g., shrimp, crab, lobster) and mollusks (e.g., clams, mussels, oysters). Understanding the symptoms of a shellfish allergic reaction is crucial for prompt recognition and treatment, as it can help prevent life-threatening complications.
Shellfish allergy can manifest in various ways, ranging from mild to severe reactions. The symptoms can occur within minutes to hours after consuming shellfish, and in some cases, even through cross-contamination or inhaling shellfish particles. It is essential to be aware of the common symptoms, which include hives, itching, swelling, stomach cramps, diarrhea, and difficulty breathing.
Common Symptoms of Shellfish Allergic Reaction
The symptoms of a shellfish allergic reaction can be categorized into two main types: cutaneous and systemic. Cutaneous symptoms affect the skin, while systemic symptoms affect multiple systems in the body.
Cutaneous Symptoms
Cutaneous symptoms are the most common and can include:
- Hives (urticaria): itchy, raised, and swollen patches on the skin
- Itching or tingling sensations on the skin
- Swelling of the face, lips, tongue, or throat (angioedema)
- Redness or flushing of the skin
Systemic Symptoms
Systemic symptoms can be more severe and life-threatening, including:
- Stomach cramps
- Diarrhea or vomiting
- Abdominal pain
- Difficulty breathing or wheezing
- Rapid heartbeat or palpitations
- Dizziness or fainting
| Symptom Category | Symptoms |
|---|---|
