Condition of Angioedema and Hives Clarified


Angioedema is something in which a swelling takes place in the skin’s inner layer and under that, and it may become severe. Sometimes, the swelling comes with the appearance of hives. Therefore, it is sometimes referred to as “giant hives.”

These hives are itchy and red colored, raised welts that develop on the surface of the skin, typically involving only the two skin layers. Urticaria is another word for hives.

Both hives and angioedema are caused by an allergic reaction or food intolerance, a side effect to a medication, or an allergy causing agent in the surrounding environment, for example pollen, pet dander, and venom from insect bites.

At times, the swelling is a symptom of a more serious health condition, such as non-Hodgkin B-cell lymphoma. There are some parts of the body which are more prone to angioedema than others for e.g. the eyelids, lips, and tongue.

When angioedema condition is passed from one generation to other through genetic transmission, the condition is referred to as hereditary angioedema. Compared to acquired angioedema, hereditary angioedema has different causes.

What are the symptoms of angioedema?

The typical symptom of angioedema is shown with swelling on skin with a red rash.

Other additional symptoms of angioedema include abdominal cramping. People with angioedema may also get a hoarseness, swollen throat, and difficulty breathing. Angioedema may or may not itch.
