What does it mean when lab results show your TSH level is elevated?

Thyroid stimulating hormone (TSH), also known as thyrotropin, is produced by the pituitary gland in the brain and causes the thyroid to make thyroid hormone. When there is not enough thyroid hormone in the body, the pituitary makes more TSH, which tells the thyroid to make and release more thyroid hormone. Therefore, when patients have elevated TSH levels, it means they are hypothyroid and have an underactive thyroid.
