Living with Herpes gestationis

An autoimmune skin condition in pregnancy that causes very itchy red bumps and blisters.

Understanding Herpes gestationis

Herpes gestationis, also called pemphigoid gestationis, is an autoimmune skin condition linked to pregnancy.

It usually starts suddenly in the second or third trimester, but can start at any time in pregnancy. Very itchy red bumps or blisters form on the belly and trunk and may spread. The itch often interferes with daily life. Symptoms may ease at the end of pregnancy, but flares may happen during or just after delivery.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Very itchy skin
  • Red bumps on the belly and trunk
  • Blisters
  • Spread to other parts of the body
  • Flare-ups around delivery

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

    Specialists who may be involved include skin, hair, and nail specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    International Pemphigus & Pemphigoid Foundation and Global Autoimmune Institute may keep lists of experts for this condition.
