Angioedema is a rare condition characterized by sudden, severe swelling of the skin and underlying tissues, often affecting the face, lips, tongue, and throat.
Types:
1. Allergic angioedema (triggered by allergens or medications)
2. Hereditary angioedema (genetic disorder)
3. Acquired angioedema (associated with underlying medical conditions)
Symptoms:
1. Sudden, severe swelling
2. Redness and warmth of the affected area
3. Pain or discomfort
4. Difficulty breathing or swallowing (in severe cases)
5. Abdominal pain or cramping
Causes:
1. Allergies (e.g., food, insect bites, medications)
2. Genetic mutations (hereditary angioedema)
3. Underlying medical conditions (e.g., cancer, autoimmune disorders)
4. Medications (e.g., ACE inhibitors, NSAIDs)
Diagnosis:
1. Medical history and physical examination
2. Laboratory tests (e.g., blood tests, allergy testing)
3. Imaging studies (e.g., CT scan, MRI)
Treatment:
1. Antihistamines or corticosteroids (for allergic angioedema)
2. C1 esterase inhibitor replacement therapy (for hereditary angioedema)
3. Medications to manage symptoms (e.g., pain, swelling)
4. Emergency treatment (e.g., epinephrine, oxygen) for severe cases
Complications:
1. Respiratory failure
2. Cardiac arrest
3. Anaphylaxis
