Angioedema is a hypersensitivity disorder that presents as edema of the subcutaneous tissues and mucosa, typically involving the upper airways or gastrointestinal tract, and often accompanied by urticaria. Although this condition could be either hereditary or acquired, the causes often overlap, with similar clinical manifestations. Diagnosis requires laboratory testing to determine serum complement levels. Treatment must be directed toward the resolution of the acute symptoms and prevention of recurrence.
