Understanding a Low TSH Level: Causes, Symptoms & What to Do

A 0.07 TSH reading indicates that the thyroid stimulating hormone (TSH) level is low. TSH is produced by the pituitary gland and regulates the thyroid gland's production of thyroid hormones.

A low TSH level usually means that the thyroid is producing too much thyroid hormone, a condition known as hyperthyroidism. Symptoms of hyperthyroidism can include:

- feeling jittery

- rapid heartbeat

- sweating

- weight loss

- insomnia

- and diarrhea.

It's important to see a doctor for further evaluation if you have a low TSH reading. The doctor may perform additional tests, such as a thyroid hormone test, to confirm the diagnosis of hyperthyroidism.
