Secondary hypothyroidism is a condition where the thyroid gland produces insufficient hormones due to a problem with the pituitary gland, which fails to produce adequate thyroid-stimulating hormone (TSH). This can result from various factors, including tumors, trauma, or other diseases affecting the pituitary. Unlike primary hypothyroidism, where the issue originates in the thyroid itself, secondary hypothyroidism indicates that the pituitary gland's dysfunction is the root cause of low thyroid hormone levels. Diagnosis typically involves assessing TSH and thyroid hormone levels, along with imaging studies if necessary.
Primary hypothyroidism is caused by a deficiency in the thyroid itself. Secondary hypothyroidism is caused by an "outside" influence, usually a medication that causes the thyroid to not secrete the necessary hormones or an insufficient quantity, or may be caused by a primary disease process that in turn affects the thyroid gland. Sometimes secondary hypothyroidism is caused by the treatments for cancer, for example.
