Urticaria-Angioedema
Urticaria-angioedema is a medical condition characterized by the sudden onset of itchy, swollen wheals (hives) and deeper tissue swelling, often affecting the face, lips, tongue, and throat. This condition can be acute or chronic, with symptoms ranging from mild to life-threatening.
Causes
The exact cause of urticaria-angioedema is often unknown, but common triggers include:
- Allergic reactions to foods, medications, or insect bites
- Infections, such as viral or bacterial infections
- Autoimmune disorders, like thyroid disease or lupus
- Hormonal changes, including pregnancy or menstruation

- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or swallowing

- Rapid heartbeat or palpitations
Diagnosis
Diagnosing urticaria-angioedema typically involves a physical examination and medical history. The following tests may be ordered to rule out underlying conditions:
- Blood tests, including complete blood count (CBC) and allergy testing
- Skin prick testing or patch testing for allergies
- Imaging studies, such as X-rays or CT scans, to evaluate the extent of swelling
Treatment
Treatment for urticaria-angioedema depends on the severity and underlying cause. Common treatments include:
- Antihistamines to relieve itching and reduce swelling
- Corticosteroids to reduce inflammation
- Epinephrine injections or auto-injectors for severe reactions
- Avoiding known triggers, such as certain foods or medications
Complications
If left untreated or poorly managed, urticaria-angioedema can lead to complications, including:
- Anaphylaxis, a life-threatening allergic reaction
- Airway obstruction, which can cause respiratory failure
- Cardiac problems, such as arrhythmias or cardiac arrest
Prevention
To prevent urticaria-angioedema, it is essential to:
- Avoid known triggers and allergens
