Can you have low thyroid with normal TSH?
If the TSH levels come back “normal,” then they often assume that everything is fine. Even if a wider panel is run, a patient can still be in normal range and yet still have low thyroid symptoms. This can be extremely frustrating to be told that nothing is wrong with you, but yet you still feel bad.
What does it mean if your TSH is low but your T3 and T4 are normal?
A low TSH with normal free T4 and T3 levels is consistent with subclinical hyperthyroidism. Some patients with nodular goiter and Graves’ disease, particularly early in the disease course, will have predominant elevations in T3 due to increased conversion of T4 to T3 and a disproportionate increase in T3 secretion.
Why would TSH be low instead of high?
A TSH level lower than normal indicates there is usually more than enough thyroid hormone in the body and may indicate hyperthyroidism. When hyperthyroidism develops, free thyroxine (T4) and free triiodothyronine (T3) levels rise above normal.
What if TSH is normal but free T4 is low?
Since the pituitary gland would normally release TSH if the T4 is low, a high TSH level would confirm that the thyroid gland (not the pituitary gland) is responsible for the hypothyroidism. If the T4 level is low and TSH is not elevated, the pituitary gland is more likely to be the cause for the hypothyroidism.
What can be mistaken for hypothyroidism?
Heart disease. Depression that occurs with hypothyroidism can worsen over time.
Can low TSH 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.
Is TSH low in Graves disease?
Blood tests can help your doctor determine your levels of thyroid-stimulating hormone (TSH) — the pituitary hormone that normally stimulates the thyroid gland — and your levels of thyroid hormones. People with Graves’ disease usually have lower than normal levels of TSH and higher levels of thyroid hormones.
Can you have Hashimoto’s with a normal TSH?
