Why Low Tsh And High T4
Few possibilities: These labs seem at odds, with TSH suggesting overactive thyroid and ft4 underactive thyroid. Free T4 tests can be inaccurate in some people who have interfering substances present. Another possibility is a tumor in the pituitary secreting too much TSH resulting in thyroid overactivity, and high thyroid hormone levels. This is quite rare, however. Your doctor can help sort this out. ...Read more
I'm concerned. I have a low TSH and high t4. I'm symptomatic of hyperthyroidism. Can't take ptu (propylthiouracil) or tapazole. What happens now?
Diagnosis first: You may or may not have grave's disease. Your doctor needs to determine the cause of your test results before treating test results. Meanwhile, if not contraindicated, a beta blocker could be useful in terms of treating hyperthyroid symptoms. Causes of your hyperthyroidism also include: hashimoto's, subacute thyroiditis, and toxic thyroid nodule. ...Read more
Very low TSH with high normal free T4. Twitching. Changed dose. How long til levels normal out? Still twitching 2 weeks later. Had basic neuro exam.
What did you: change the dose of? If it's thyroid replacement, it can take weeks for the level to normalize, asumming you're now on the correct dose. If it's an ANTI-thyroid drug, it can takes months to work as it only inhibits the formation of NEW thyroid hormone, not the hormone that's already been manufactured. ...Read more

My 10yr old daughter had lab work completed and the results show a high esr, low tsh, and normal t3/t4. What are possible diagnosis?
Possibly thyroiditis: The information is incomplete, but subacute thyroiditis (sat), an inflammation of the thyroid gland can cause hyperthyroidism and high esr. People with sat have severe neck pain. With no pain sat is unlikely. A high ESR is found in many non-thyroid conditions: one can have mild hyperthyroidism and another cause for a high esr. Some people with non-thyroid illness have low TSH without being hyper. ...Read moreSee 2 more doctor answers
Had total thyroidectomy 10 years ago. Currently 8 weeks pregnant, taking synthroid (thyroxine) 125mcg. Very low TSH 0.01 and high free T4 at 26 (normal 12-22). ?
Way off: That dose of thyroid needs to be reduced ASAP. Please consult with your doctor right away. I'm guessing they're doing that already if they received those test results. ...Read more
