What is Hashimoto’s Disease?

Causes And Risk Factors

Like most autoimmune conditions, there is no known cause of Hashimoto's disease. However, certain factors, such as gender and age increase the risk of developing it. Hashimoto’s can develop at any age, though most cases tend to occur in middle-aged individuals. Women are seven times more likely than men to develop this condition, which suggests sex hormones play a role. Women are more likely to receive a diagnosis within the first year after giving birth. Although most thyroid problems will dissipate over the years, approximately twenty percent of these women will develop Hashimoto’s disease later in life. Genes also play a significant role in the disease's development as individuals who get Hashimoto’s often have a relative with the condition.

Other potential contributing factors include excessive iodine levels, certain medications, and exposure to radiation. Individuals who have been exposed to radiation such as the atomic bombs in Japan, radiation treatment for blood cancer, and the Chernobyl nuclear accident may be at an increased risk for developing Hashimoto's disease. Having other autoimmune conditions, such as lupus, type one diabetes, and rheumatoid arthritis, may also increase the risk of developing Hashimoto's disease.
