What Are the Dangers of Extremely Low TSH Levels?. Low TSH levels indicate your body is producing too much thyroid hormone. This hormone serves many important functions, and excessive levels can cause a number of problems.
But in the typical and most common form of hypothyroidism, the main thyroid hormone T4 is low, and the TSH level is high. The next question is: When is low too low, and when is high too high? Blood levels have "normal" ranges, but other factors need to be taken into account as well, such as the presence or absence of symptoms.

Some symptoms of low TSH levels due to secondary hypothyroidism are fatigue, depression, weight gain and cold intolerance, states UCLA Endocrine Surgery.
Extremely low levels of thyroid hormone can cause a life-threatening condition called myxedema. Myxedema is the most severe form of hypothyroidism. A person with myxedema can lose consciousness or ...
The thyroid gland is an organ that produces hormones that regulate important bodily functions, including metabolism. The thyroid is stimulated to produce its hormones by another hormone called thyroid stimulating hormone, or TSH. When thyroid hormone levels are abnormally high, TSH is typically low.
A low TSH level is not always due to suppression caused by high thyroid hormone levels, other conditions, or medications. If thyroid hormone levels are low, a low TSH value can be the result of a central process (hypothalamic or pituitary or both). Severe euthyroid sick syndrome (also called “nonthyroidal illness” or “low T 3 syndrome”).

Low TSH Levels – Symptoms, Causes & What to Do. Healthcare. The pituitary gland releases the thyroid-stimulating hormone (TSH), which is responsible for stimulating the release of the thyroid hormones namely thyroxine (T4) and triiodothyronine (T3). These two thyroid hormones are necessary for various body functions.
