A low TSH and high T4 generally indicates hyperthyroidism. A high TSH and low T4 indicates primary hypothyroidism (due to a thyroid disease). A low TSH and low T4 suggest secondary hypothyroidism (due to a disease of the pituitary gland or hypothalamus of the brain).
What happens if T3 and T4 are high?
High amounts of T4, T3, or both can cause an excessively high metabolic rate. This is called a hypermetabolic state. When in a hypermetabolic state, you may experience a rapid heart rate, elevated blood pressure, and hand tremors. You may also sweat a lot and develop a low tolerance for heat.
What happens when TSH is too 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. Symptoms of hyperthyroidism include: an irregular or rapid heartbeat.
What does low TSH and high T4 mean?
The finding of an elevated TSH and low FT4 or FTI indicates primary hypothyroidism due to disease in the thyroid gland. A low TSH and low FT4 or FTI indicates hypothyroidism due to a problem involving the pituitary gland. A low TSH with an elevated FT4 or FTI is found in individuals who have hyperthyroidism. T3 TESTS.
What happens if T3 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.
What is a good TSH level for a woman?
The normal range of TSH levels in non-pregnant adult women is 0.5 to 5.0 mIU/L. In women, during the menstruation cycle, pregnancy, or after menopause, TSH levels may fall slightly outside the normal range, because of fluctuating levels of estrogen.

Is Tsh 0.02 normal?
TSH helps regulate the levels of thyroid hormones in the body. In healthy people (with normally functioning thyroid glands), TSH should be to be about 0.4 to 5.0 µIU/mL. In people with thyroid cancer, TSH drops to 0.01 to 3.0 µIU/mL.
Does low TSH cause weight gain?
Weight gain may signal low levels of thyroid hormones, a condition called hypothyroidism. In contrast, if the thyroid produces more hormones than the body needs, you may lose weight unexpectedly. This is known as hyperthyroidism. Hypothyroidism is far more common.
What is the treatment of low TSH?
Standard treatment for hypothyroidism involves daily use of the synthetic thyroid hormone levothyroxine (Levo-T, Synthroid, others). This oral medication restores adequate hormone levels, reversing the signs and symptoms of hypothyroidism.

How do you interpret TSH results?
A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism. Your doctor may also order a T4 test. Most of the T4 in your blood attaches to a protein, and when it does, it can’t get into your cells.
Can high T3 cause weight gain?
According to Dr. Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.
What is the treatment for high T3?
Antithyroid Medications: Antithyroid medications (sometimes written anti-thyroid) prevent the thyroid from producing excess amounts of T4 and T3 hormones. There are 2 types of antithyroid medications used in the US—propylthiouracil (PTU) and methimazole (also known as Tapazole).
