Learn how TSH levels indicate thyroid health. High TSH suggests an underactive thyroid; low levels point to overactivity.
This article describes the TSH test and its results. We also discuss what high and low TSH levels indicate and available treatments.
TSH stands for thyroid stimulating hormone. Another name for it is thyrotropin. A TSH test is a blood test that measures this hormone. A TSH level that is too high or too low may be a sign of a thyroid problem. The thyroid is a small, butterfly-shaped gland in the front of your neck.
Thyroid stimulating hormone, or TSH, is produced by the pituitary gland and helps regulate thyroid hormone levels in the body. Learn the high TSH symptoms, such as fatigue and dry skin, and what elevated thyroid levels mean.
