Thyroiditis facts

*Thyroiditis facts medically edited by: Charles Patrick Davis, MD, PhD

  • Thyroiditis is inflammation or swelling of the thyroid gland.
  • There are several types off thyroiditis; Hashimoto's, postpartum, silent or painless and subacute.
  • Symptoms of Hashimoto's thyroiditis may include fatigue, depression, cold intolerance, weight gain, dry skin and hair, muscle cramps, constipation, decreased concentration and sleepiness, leg swelling, puffy eyes; severe symptoms include a slow heart rate, low body temperature, heart failure and coma – cause is suspected immune mediated reaction.
  • Postpartum thyroiditis may have two phases; phase one occurs about 1 to 4 months after giving birth when symptoms of hyperthyroidism occur and phase two that starts 4 to 8 months after delivery when the patient develops hyperthyroiditis symptoms – most women with postpartum thyroiditis return to normal function after 12 to 18 months and not all women go through phase two.
  • Silent or painless thyroiditis develops like postpartum thyroiditis, but the person is not pregnant.
  • Symptoms of subacute thyroiditis can be the same as postpartum thyroiditis, but it may also include neck, jaw, or ear pain.
  • In contrast to other thyroid types, subacute thyroiditis can be caused by infection.
