What causes T3 syndrome?
High T3 levels can indicate several conditions, including hyperthyroidism and thyrotoxicosis (excess circulating hormones). In some cases, they can signify thyroid cancer, but this disease does not often cause abnormal T3 levels. Thyrotoxicosis and thyroid cancer are rare, so hyperthyroidism is more commonly the cause.
What happens if T3 level is high?
If your results show high total T3 levels or high free T3 levels, it may mean you have hyperthyroidism. Low T3 levels may mean you have hypothyroidism, a condition in which your body doesn’t make enough thyroid hormone. T3 test results are often compared with T4 and TSH test results to help diagnose thyroid disease.
Does T3 affect your heart?
The major effects of thyroid hormones on the heart are mediated by triiodothyronine (T3) (Fig 2). Indeed, T3 generally increases the force and speed of systolic contraction and the speed of diastolic relaxation.
What is low T3 syndrome?
Low T3 syndrome, which is also known as non-thyroidal illness syndrome or sick euthyroid syndrome, is characterized by a low serum level of free triiodothyronine (FT3) accompanied by normal-to-low serum free thyroxine (FT4) and thyroid-stimulating hormone (TSH) levels13.
How do you check T3 levels?
A laboratory test can be done to measure the amount of T3 in your blood. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe.
How can I lower my T3 naturally?
Poor conversion of T4 to T3 often boils down to chronic inflammation. To help lower inflammation, follow an anti-inflammatory diet that is rich in fruits, veggies, wild-caught fish, nuts, seeds, and legumes. Limit foods that may worsen inflammation like refined grains, processed foods, alcohol, and added sugar.
What are the side effects of too much T3?
Normally, these T3 side effects on heart rate and heartbeat are associated with very high T3 doses. Other more rare Cytomel side effects (often associated with overdose) includes: headaches, irritability, sweating, nervousness, irregular heartbeats, menstrual irregularities, and increased bowel movements.
What medications cause low T3 levels?
Some medications that can affect your T3 levels include: thyroid-related drugs steroids birth control pills or other medications containing hormones, such as androgens and estrogens
