Tsh Average Percentile
36 weeks pregnant. Taking 50mg of levothiroxine daily. TSH/T4 perfectly normal a month ago. Baby super active, measuring 40 percentile. I'm loosing considerably weight and appetite since a week, could this be related to current dose at this stage?
Possible: The dose of levothyroxine required does vary through pregnancy and after delivery. Discuss your weight loss and loss of appetite with your OB at your next visit. Normally these should be weekly at this point in pregnancy and you should be being weighed every visit. Hope this helps. Best wishes to you and the baby. ...Read more

High levels of TSH mean the pituitary thinks the body needs more thyroid hormone(that thyroid levels are too low), and low levels of TSH mean that the pituitary thinks the body needs less thyroid hormone. ...Read more

Tsh can fluctuate if you are on the wrong kind of thyroid replacement, or you are not taking it regularly, or lab misinterpretation...Work closely with your doc or see a thyroid specialist if this continues to be a problem. ...Read moreSee 1 more doctor answer
No: Tsh is produced in the anterior pituitary gland in the brain. Its function is to regulate thyroid hormone production in the thyroid gland itself. The TSH test is just to monitor that feedback loop. If there is too little thyroid hormone, then that is given exogenously because that has a physiologic function. Tsh does not. If the pituitary is treated if it's abnormally producing extra tsh. ...Read moreSee 1 more doctor answer
