What does a low TSH level indicate?
A low TSH often, but not always, means that a person has an elevated level of thyroid hormones. While often associated with hyperthyroidism, a low TSH could also be a sign of central hypothyroidism.
What does it mean when your TSH is low?
Low TSH levels indicate hyperthyroidism. This is also known as an overactive thyroid. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH. The TSH test involves a healthcare professional drawing blood from a vein in the inner arm. They then send the blood sample to a laboratory for testing.
Is a low TSH level dangerous?
Low TSH levels indicate your body is producing too much thyroid hormone. These complications can include a variety of heart problems, weak bones, eye and skin problems, and thyrotoxic crisis—a serious condition that can cause delirious behavior. In rare cases, your doctor might recommend removing most of your thyroid gland.
What causes high TSH levels?
Causes for elevated TSH include Hashimoto’s Thyroiditis, an autoimmune condition in which the body’s own immune system attacks the thyroid; pregnancy; and pituitary gland disorders.
