These factors may contribute to your risk of developing Hashimoto's disease:

  • Sex. Women are much more likely to get Hashimoto's disease.
  • Age. Hashimoto's disease can occur at any age but more commonly occurs during middle age.
  • Heredity. You're at higher risk for Hashimoto's disease if others in your family have thyroid or other autoimmune diseases.
  • Other autoimmune disease. Having another autoimmune disease — such as rheumatoid arthritis, type 1 diabetes or lupus — increases your risk of developing Hashimoto's disease.
