Understanding Hereditary Angioedema

Hereditary Angioedema (HAE) is a rare genetic disorder characterized by recurrent episodes of severe swelling in various parts of the body, including the limbs, face, intestinal tract, and airway. These episodes can be unpredictable and potentially life-threatening, especially when they involve the airway. HAE is caused by a deficiency or dysfunction of the C1 inhibitor protein, leading to increased levels of bradykinin, which promotes vascular permeability and swelling.

Market Size and Share

The global hereditary angioedema treatment market has been experiencing significant growth. In 2024, the market was valued at approximately USD 5.59 billion and is projected to reach USD 19.68 billion by 2032, exhibiting a Compound Annual Growth Rate (CAGR) of 17.1% during the forecast period of 2025-2032 . North America currently dominates the market, accounting for a substantial share due to advanced healthcare infrastructure and increased awareness check out Expert Market Research's Hereditary Angioedema Drug Pipeline Analysis report.
