2. Hypothyroidism Causes
There are numerous potential reasons why the thyroid gland might stop functioning as it should do. One potential cause is Hashimoto’s disease, which is an autoimmune condition that causes the thyroid gland to be attacked by the patient’s immune system. In a small number of cases, people are born with a dysfunctional thyroid gland.
Other potential causes include a lack of iodine in the patient’s diet, although this is not common in parts of the world where people have easy access to a balanced diet. Previous surgery or other treatment of the thyroid gland can also lead to hypothyroidism.
