Question 1

Male 26.havin no/very low libido+ed.thyroid profile(tsh:7 micro iu/ml, t3:0.8 ng/ml, t4:6.45ncg/100ml).is thyroid the culprit?no other medical history.

Accepted Answer

Looks like you are hypothyroid which can cause some of the symptoms you describe. I would see your doctor to get this treated and see if the symptoms improve.  No other exotic labs needed unless the symptoms don't improve on thyroid replacement.

Question 2

I have subclinical hypothyroidism.tsh:7.03.t3, (liothyronine) t4 normal.can it cause low libido or e.d. ? because i am facing these peoblems for last one year.

Accepted Answer

Fatigue and low libido can be a result of hypothyroidism.

Question 3

What could be causing excessive hair loss, extreme heat intolerance, low libido, jaw/cheek acne, & irregular periods? ive had tsh checked recently and it was normal?

Accepted Answer

In addition to hyperthyroidism, other causes of heat intolerance include certain medications, stress&anxiety,ovarian insufficiency. Hair loss can be from hormonal imbalance or hereditary factors. A dermatologist can advise you about hair loss and your acne. I assume you've consulted your gynecologist, also.

Question 4

What does it mean if i have low tsh and low freet4? both .6

Accepted Answer

Are you taking thyroid hormone? If yes, it changes how the tests are interpreted.  If you are not on thyroid medication, a low free T4 and low TSH can indicate a pituitary disorder.

Question 5

What does it mean when you have a low tsh but you also have a low t4?

Accepted Answer

Hi. See an endocrinologist. Make sure it's a free T4 (not a TOTAL T4). If you have low TSH and a low free T4, that's compatible with pituitary disease causing hypothyroidism (so called "secondary hypothyroidism"). IF you have that (not saying you do), you need to be checked for pituitary problems and other pituitary deficiencies (adrenal, most promptly); If u have secondary hypothy, CHECK ADRENALS

Question 6

Stress can increase tsh, but how high cortisol causes low tsh where as stress causes high cortisol production.?

Accepted Answer

This is a very complex system. In very basic terms cortisol is produced in response to stress and feeds back inhibiting production of itself (inhibiting crh and acth). Cortisol also inhibits TSH production (as well as growth hormone, estrogen, testosterone and lh production). Thus limiting the response to stress. It is though in chronic stress this feedback mechanism breaks down.

Question 7

How long does your body adjust to a dose change in synthroid? ex from 100 mcg to 88 mcg bec of low tsh. when do you start to feel better?

Accepted Answer

It may take up to a month or so for your body to adjust. As your body becomes more accustomed to the lower artificial hormone supplementation, you will feel less tired, cold sensitivity, weight changes, constipation and other symptoms. Make sure to keep your Dr informed about any changes in symptoms so that they can adjust your medication accordingly.

Question 8

27 yrs old. this years blood work showed: low tsh, and total t-3 and free t-4 are both high. last year's test were fine. what could thus indicate?

Accepted Answer

Unless you are taking thyroid medication (and taking too much) this could mean mild hyperthyroidism.  If your doc measured TSH, FT3 and FT4, (s)he must have suspected something. Most likely cause of hyperthyroidism in a 27 yo woman is Graves disease or one of several forms of thyroiditis. You may need to see an Endocrinologist.

Question 9

What does low tsh mean?

Accepted Answer

Thyroid stimulating hormone.
It is secreted by pituitary gland to make your thyroid gland produce thyroid hormone.

Question 10

What does a low tsh level mean?

Accepted Answer

And free t4. Low tsh, depending on the sensitivity of the assay, indicates thyroid hyper-function. However, the suspected hyperthyroidism needs to be confirmed with high levels of T3 (liothyronine) and free t4. All lab tests need to be evaluated in the clinical context and it would be prudent to take up the issue with your doctor.
