What would cause a low T3 (liothyronine) level but normal TSH and T4 levels? Would that be considered hypothyroidism?

What would cause a low T3 (liothyronine) level but normal TSH and T4 levels? Would that be considered hypothyroidism?

No: Low t3 (liothyronine) with nl TSH and T4 is not hypothyroidism. Many things can make t3 (liothyronine) levels decrease such as illness, stress, colds etc. It is nonspecific and could also be lab error so low t3 (liothyronine) in the face of nl TSH and free T4 levels does not mean very much. ...Read more

I have hypothyroidism on low level is 0.098 and now I am pregnant my age is 25?

TSH?: You need to tell us what blood test was 0.098. If this was a TSH level, it implies that your thyroid level may be high. You should get a free t4, free t3, (liothyronine) and TSH level done. ...Read more

Hemoglobin 12, ferritin 7. 41 year old female. Hysterectomy 9 years ago. What could cause the low ferritin? Other medical conditions: hypothyroid, dia

Blood tests: There are a few diseases that leap out from blood tests. Most of the time, however, blood tests don't tell the doctor much on their own. These results fall into the second group, not very specific. Low ferritin is not nearly as worrisome as high ferritin. ...Read more

Can you get hypothyroid symptoms from low levels of t3 (liothyronine) only? Would this be treated?

Doubtful: The T3 (liothyronine) test is not as reliable as the free T4 test and it is not rare to see patients with somewhat low or high T3 (liothyronine) levels whose thyroid is working properly. If your total or free T4 and your TSH are normal I would not be concerned about your T3 (liothyronine). We mainly treat when TSH is elevated. ...Read more

T3 (liothyronine) level was 2.3, with 2.0 being the low point of the range. Would this be considered hypothyroid?

T3 (liothyronine) level was 2.3, with 2.0 being the low point of the range. Would this be considered hypothyroid?

Possibly, depends on:: Most docs would say that it is fine. I disagree. The "normal range" is where 95% of folks lie, but I believe at least 20% of people are clinically hypothyroid and about 3/4 of those have "normal tests." I find most of my patients who are hypothyroid remain symptomatic until their Free T3 (liothyronine) is in the upper half of the range. See http://tinyurl. Com/koyamo5 and http://tinyurl.

I have hypothyroidism and chronic stress/anxiety. Does low cortisol cause hypothyroidism?

I have hypothyroidism and chronic stress/anxiety. Does low cortisol cause hypothyroidism?

No: Cortisol is made by the adrenal glands whereas hypothyroidism refers to low levels of thyroid hormone from the thyroid gland. Having one does not cause the other. Chronic stress and anxiety also do not cause these disorders. Low cortisol (adrenal insufficiency) is a rare disorder, typically autoimmune related, and must be diagnosed correctly, not simply by a low cortisol level. ...Read more

Could birth control cause you levels to suggest you have hypothyroidism when actually you do not?

Could birth control cause you levels to suggest you have hypothyroidism when actually you do not?

No: The estrogen in birth control pills increase the levels of thyroid hormone binding proteins in the blood. This requires your thyroid to make more hormone to fill up the binding sites. If the thyroid is not working well, it will result in lower blood levels of thyroid hormone and a rise in tsh, the test used to determine hypothyroidism. A rise in TSH with birth control pills means hypothyroidism. ...Read more

What do I do if my TSH levels are normal, but my free T4 is low, and I am having hypothyroid symptoms?

What do I do if my TSH levels are normal, but my free T4 is low, and I am having hypothyroid symptoms?

Central hypothyroid: Free T4 assays can sometimes be unreliable and you and your physician will be better off if you have your total T4 measured instead along with T3 (liothyronine) update to calculate what we call free thyroid index. If you have symptoms of hypothyroidism and your T4 remain level despite normal TSH then you may have a type of hypothyroidism called central hypothyroidism (your pituitary hormones should be checked). ...Read more

Can a high TSH level but normal T4 cause hypothyroid symptoms or not?

Can a high TSH level but normal T4 cause hypothyroid symptoms or not?

Yes: Hypothyroidism can be primary - caused by a weak thyroid gland or secondary to other hormonal problems, like a pituitary problem. Or your thyroid can become dysfunctional secondary to high insulin, estrogen or cortisol. If you have functional hypothyroidism, this problem can go undetected by routine screening tests. More extensive testing can often reveal abonormalities. This is very common. ...Read more
