Quizplus · Accepted Answer

A low level of TSH indicates a problem with the pituitary gland, which produces TSH to stimulate the thyroid gland. This is known as secondary hypothyroidism. Primary hypothyroidism occurs when the thyroid gland itself is not functioning properly, and autoimmune hypothyroidism is a subtype of primary hypothyroidism caused by autoimmune damage to the thyroid gland. Atypical hypothyroidism is not a recognized subtype.
