Is a test result of 0.4 very low? Was told that the normal range is 0.5 to 5, and below 0.5 is hyperthyroid. However, have also read reports of new studies suggesting the normal range should be 0.3 to 3.04, meaning that 0.4 would actually be in the normal range?
Any opinions on that? And if 0.4 indeed does suggest hyperthyroid, I assume it means its mild?
Hi there, Do you have any negaive symptoms of hyperthyroid? Is that the reason you were getting tested? Well the new guidlines state, the new level is 0.3-3.0, so yes you are in normal range, but on the low end. However, I have seen those numbers go extremely low in classic Hyperthyroid patients. I would be most concerned if you are having some troubling symptoms, this would answer alot about your numbers. Unfortunatley everyone is different and different people feel real good at different TSH levels, What are your symptoms? some common Hyper symptoms include, weight loss, inability to gain weight, hair loss, diarrea, anxiety, heart palpitations, chest pain, shortness of breath, joint and muscle pains, headaches, insomnia, etc.... Are you experiencing any of these? Let us know. Also along with your TSH did you have any other thyroid tests done like a T3 or T4? Keep us posted, and there's some great advice givers on here. good luck. Shannon
I'm actually not the person in question, I'm asking for my girlfriend. I just want to be super informed, and make sure she gets the best and most correct treatment possible, if it turns out anything is actually wrong. She's my everything. As far as classic symptoms, she is thin and never has to worry about gaining weight, and I do know she seems to have anxiety sometimes.
The lower limit of normal for TSH varies from lab to lab - some will be as low as 0.275. A value less than 0.1 is definetely too low (except in case of high risk cancer patients) and is associated with increased risk of heart rhythm problems and osteoporosis. Typically hypothyroid patients should be treated to a TSH that ranges from the lower limit of normal for that lab up to about 2.0 (some say 2.5) - and symptoms should be taken into account as there is individual variability.
She is going in tomorrow to have a sonogram of her thyroid, the doctors say this is just to be extra safe, and that she shouldn't be alarmed.
I guess if there really is a problem, since its seemingly mild, it should be treatable w. some anti-thyroid medications? (As opposed to destroying the thyroid, going hypo, and then treating ther hypo? I assume that is reserved for more severe cases?)
