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.
