What are the symptoms of too much T3?
As its name suggests, hyperthyroidism occurs when your body makes too much of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), and becomes overactive. If you have hyperthyroidism, you may experience a fast heartbeat, increased appetite, anxiety, sensitivity to heat, or sudden weight loss.
Can T3 damage your thyroid?
While T3 drugs like Cytomel may seem the ideal choice for hormone replacement therapy, T3 is rapidly absorbed in the intestines and can build up quickly, leading to symptoms of hyperthyroidism (overactive thyroid). After that spike, the level then drops quickly, along with your body's ability to create T4.
What happens when T3 increases?
Higher-than-normal T3 levels typically indicate hyperthyroidism (overactive thyroid). Hyperthyroidism has several causes, including Graves' disease (an autoimmune condition), thyroid nodules and thyroiditis (inflammation of your thyroid gland).
