Living with Behcet disease

An inflammatory condition that affects blood vessels, often causing mouth sores and eye, skin, and joint problems.

Understanding Behcet disease

Behcet disease is an inflammatory condition caused by widespread swelling of blood vessels (vasculitis).

It most often affects small blood vessels in the mouth, genitals, skin, and eyes. Painful mouth sores are usually the first sign. Eye inflammation (uveitis) occurs in more than half of people, and joint swelling is also common. It can begin from childhood to adulthood.

Signs & symptoms

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

  • Painful mouth sores
  • Genital sores
  • Acne-like bumps and red tender nodules on the skin
  • Eye inflammation and light sensitivity
  • Swollen, painful joints (arthritis)
  • Fever, headache, and fatigue

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 autoimmune and inflammatory disease specialists, brain and nervous system specialists, eye disease specialists and kidney 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

    Autoimmune Association, Global Autoimmune Institute and Vasculitis Foundation may keep lists of experts for this condition.
