This biopsy involves getting a small sample of the thyroid gland with a special needle inserted through the skin. This sample can be examined under a microscope to make the diagnosis. Hashimoto's thyroiditis often causes low thyroid hormone levels, or hypothyroidism . This may be permanent, requiring thyroid hormone replacement medication for life. There are no risks to others, as this disease is not contagious.
Treatment generally focuses on the level of thyroid hormone.
If the level is low, as it is in most cases, thyroid hormone pills are needed. If the thyroid level is high, other medications are needed to block thyroid hormone from working in the body. Rarely, surgery may be needed if the thyroid gland gets too big. All medications have side effects. If too much thyroid medication is given, the levels can become toxic.
