Not thyroid: With the exception of frequent palpitations your symptoms are characteristic of an underactive thyroid, but your tsh and free t4 don't show that. I recommend an evaluation by an internist who will take a thorough history and system review, perform a complete physical examination and order a battery of appropriate tests in order to make a differential diagnosis. Referral to other specialists possib

Q: normal range tsh and free t3 but low t4?? just had my thyroid labs done - tsh - 1.88, free t3 - 3.3 and free t4 is .87. what would cause this? i dont sleep great with my 2yo waking up every night but why is t4 low? is t3 high?is this a bad balance?

: The Dr who ordered these tests knows your entire history and any current symptoms. They are the best resource for reading these labs in the correct context of your full medical history/exam/other labs. It would not be appropriate for a Dr online to try and determine a diagnosis based on two lines of information.

Q: my tsh is high end of normal at 0.66, free t4 is 1.3 but my free t3 (liothyronine) is low end of normal at 2.7. why does my tsh not better correlate with free t3/t4?

Hard to say,,: First, the TSH isn't at high normal, more like low normal (0.4-2.5uiu/ml), next is that the ft4 is at a high normal value. The ft3 is around low normal but it has a low half life so that might be why. You've got a history of hashimoto's which leads to hypothyroidism and take synthesis for replacement which can explain these values so it's good to see your doctor for a possible med adjustment.

Q: tsh is high end of normal at 0.66, free t4 is 1.3 but free t3 (liothyronine) is low end of normal at 2.7. t3 (liothyronine) and t4 down 1 point in 1 month. felt better before. why?

Normal TSH: They key word is "normal". Your TSH is normal, which means your pituitary believes your thyroid hormone levels are normal, and the pituitary is usually right. You list a number of autoimmune rheumatologic disorders. These may be responsible for your symptoms, rather than your thyroid. See your rheumatologist.

Q: tsh high (15) free t4 high (4.2) but free t3 low (2.1). 41 yrs old, has partial thyroid removal at 14. hashimoto. been on 300 mg of generic synthroid for 20 years. what does this mean?

Thyroid or pituitary: Not clear since both TSH and free T-4 are high. No data on T-4 Hashimoto can effect the thyroid tests either over acive and underactive and synthroid can effect them and raise them. Was thyroid removed because there was a tumor or was it overactive or underactive. A visit to an endocrinologist is in your future

Q: thyroid antibodies are high, my free t4 low, tsh & free t3 (liothyronine) in normal range, on whole thyroid yet exp 2-4lb weight fluctuation & hair loss- what next?

Imaging: If not done so, proper imaging of the thyroid is indicated, including ultrasound and nuclear thyroid uptake scan. You may be suffering from hashimoto's thyroiditis, an immunologic condition that affects your thyroid gland causing inflammation and often leads to an underactive thyroid gland (hypothyroidism). Hashimoto's disease is the most common cause of hypothyroidism in the United States.

Question 1

high tsh (6.0) , normal free t4 and free t3. free t4 is 1.5 (range up to 1.77). hypothyroid symptoms , excessive weight gain. safe to take synthroid 50 mcg even with higher than normal free t4?

Accepted Answer

: Given higher than normal value of TSH plus symptoms reflecting hypothyroidism,  replacement treatment is certainly indicated.

Question 2

Accepted Answer

Normal thyroid lab studies.: Your thyroid lab studies are within normal limits on whatever dose of Synthroid (thyroxine) you are now taking. Hypothyroidism particularly if due to Hashimoto's thyroiditis can be associated with other autoimmune entities such as pernicious anemia characterized by low B12 levels. in that situation B12 must be administered either sublingually daily or intramuscularly on a monthly basis. Active menses?

Question 3

i am a 37 y/o female who has been feeling serious fatigue. my tsh is 1.5, free t3 (liothyronine) is 2.5, and my free t4 is .5. should i be treated for hypothyroidism?

Accepted Answer

Hypothyroidism: The most sensitive study for hypothyroidism is the TSH as a rule. Not knowing the standards for the laboratory makes decision making difficult but your labs appear normal based on standards that I am familiar. Other causes for your symptoms must be persued.

Question 4

tsh 2.05 free t4 1.4 free t3 285. are these normal? i've gained weight and cannot lose any. very sensitive to cold.  extreme fatigue. hair loss 29yr/f
