What happens if angioedema is not treated?

Angioedema is swelling in deeper layers of the skin or lining tissues. It may affect the face, lips, eyelids, hands, feet, or genitals and can occur with Hives, although hives are not always present. Mild episodes may settle, but swelling can become extensive or return if the trigger continues. The most serious concern is swelling inside the mouth, tongue, throat, or upper airway, where narrowing can interfere with breathing or swallowing. Abdominal swelling may cause cramping, vomiting, or severe discomfort and also needs assessment.

Stop and record any suspected new medicine, food, or exposure, but do not delay urgent care to identify the trigger. A clinician may recommend Antihistamine Treatment for histamine-related swelling or Oral Corticosteroid Treatment in selected cases. Take medicines only as directed, and tell every healthcare professional about previous episodes, especially if swelling followed a medicine. Recurrent attacks need a plan for avoiding triggers and responding early.

Call emergency services immediately for tongue or throat swelling, trouble breathing, wheezing, a tight throat, faintness, confusion, blue lips, or difficulty swallowing saliva. Do not wait to see whether facial swelling improves. Sudden extensive Facial Swelling, Swollen Lips, or Skin Swelling should receive prompt medical advice even when breathing is currently normal.

What type of angioedema is most likely? Could a medicine be responsible? What should I take at the first sign? Which symptoms mean I should call emergency services? Do I need an allergy or medication review?
