Living with Episodic angioedema with eosinophilia

A condition with repeating episodes of swelling under the skin, hives, and fever that clear up on their own.

Understanding Episodic angioedema with eosinophilia

Episodic angioedema with eosinophilia is a condition with repeating episodes of swelling under the skin and a high count of eosinophils (a white blood cell).

During episodes, people may have hives, fever, swelling, and weight gain. Episodes usually come every 3 to 4 weeks and clear up on their own within several days. GARD says it does not typically involve organs or lead to other health concerns.

Signs & symptoms

Symptoms vary from person to person. GARD describes these during episodes:

  • Swelling under the skin (angioedema)
  • Hives (urticaria)
  • Fever
  • Weight gain from swelling
  • High eosinophil count in the blood

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    American Partnership For Eosinophilic Disorders may keep lists of experts for this condition.
