evidence: At the University of Michigan, each patient is carefully evaluated by our team of experts so the best decision can be made on the most appropriate course of treatment. Deciding which treatment is best for each patient depends on the cause and severity of the disease, as well as a number of other factors. We see patients with a wide range of thyroid disorders, including: [...] - Hypothyroidism is a disorder caused by an under-active thyroid that may lead to changes in the hair or skin, fatigue and weakness, memory problems, or other issues. Hashimoto’s Thyroiditis, also known as Hashimoto’s disease, is an autoimmune disease that causes the body’s immune system to produce antibodies that attack thyroid tissue and damage the gland, leading to an under-productive thyroid. Hypothyroidism can usually be easily treated with thyroid hormone medicine, typically levothyroxine, which is identical to the main thyroid hormone made by the thyroid gland.
