What is hereditary angioedema (HAE)? Angioedema is a condition characterized by the sudden and rapid swelling of the skin, subcutaneous tissues, and mucous membranes. It is a result of an allergic reaction or a hereditary disorder known as hereditary angioedema (HAE). The swelling usually occurs around the eyes, lips, tongue, hands, and feet, and can also cause difficulty breathing. The symptoms of angioedema can be managed with various treatments, such as antihistamines, corticosteroids, and epinephrine injections. If you have angioedema, it is essential to know which foods to avoid to prevent allergic reactions and worsening of the condition. Here are five foods that should be avoided with angioedema and why:

1. Shellfish
Shellfish such as shrimp, crab, and lobster contain high levels of a protein called tropomyosin, which can trigger an allergic reaction in some people. If you have angioedema, it is best to avoid these foods or consult your doctor before consuming them.

2. Nuts
Nuts, especially peanuts, are a common allergen that can trigger angioedema. Peanuts contain a protein called arachin, which can cause an allergic reaction in some individuals. Other nuts like almonds, cashews, and walnuts can also cause allergic reactions and should be avoided.

3. Dairy products
Dairy products such as milk, cheese, and yogurt can contain a protein called casein, which can trigger an allergic reaction in some people. If you have angioedema, it is best to avoid dairy products or choose non-dairy alternatives such as soy or almond milk.

4. Citrus fruits
Citrus fruits such as oranges, lemons, and grapefruits contain high levels of histamine, which can trigger an allergic reaction in some individuals. Histamine is a chemical that the body releases in response to an allergen, which can cause inflammation and swelling.

5. Spicy foods
Spicy foods such as chili peppers, hot sauce, and curry contain capsaicin, which can cause an allergic reaction in some people. Capsaicin can cause an increase in histamine levels, leading to angioedema symptoms such as swelling and inflammation.

In conclusion, if you have angioedema, it is crucial to avoid foods that can trigger an allergic reaction or worsen the condition. These include shellfish, nuts, dairy products, citrus fruits, and spicy foods. If you experience any symptoms of angioedema, such as difficulty breathing, seek medical attention immediately. Your doctor can provide you with a personalized treatment plan to manage your symptoms and help you avoid potential allergens.
