Hypothyroidism : Your TSH is a substance made in the brain. When high it indicates the possibility that your thyroid gland is not able to make enough thyroid hormone. In some cases, it takes a repeat test to clarify this was not a false test, but at your age, and depending on how well or not you feel, it might indicate the need to start thyroid replacement treatment. Please review these tests with your doctor.
