What Are the Different Types of Angioedema?

The different types of angioedema include:

  • Allergic Angioedema: Triggered by allergens such as food, medications, insect stings, or latex.
  • Non-Allergic Drug Reactions: Certain medications, such as ACE inhibitors, can cause angioedema as a side effect without involving an allergic mechanism.
  • Angioedema (HAE): A genetic disorder resulting from a deficiency or dysfunction of the C1 inhibitor protein, leading to recurrent episodes of severe swelling.
  • Idiopathic Angioedema: When the cause of angioedema is unknown.
