Hashimoto’s Thyroiditis




The thyroid gland becomes inflamed, impairing its ability to produce thyroid hormones. This leads to a gradual decline in function and eventually an underactive thyroid, which causes many functions of the body to slow down.

Common Symptoms

Fatigue, increased sensitivity to cold, constipation, pale and dry skin, puffy face, irregular or heavy menstruation, brittle nails, hair loss, tongue enlargement, unexplained weight gain, depression, muscle aches, stiffness, and weakness, joint pain, and stiffness.

Risk Factors

Having pre-existing autoimmune diseases, family members with Hashimoto’s, being female, pregnant, and/or being over 30, and exposure to environmental factors such as radiation have all been found to increase the risk of developing Hashimoto’s thyroiditis.
