Weight gain, irregular menstrual periods and acne. TSH - 6.50 ulU/ml, Free T3 - 4.28 pmol/l, T4 - 13.85 pmol/l. Take Eltroxin for hypothyroidism?

Weight gain, irregular menstrual periods and acne. TSH - 6.50 ulU/ml, Free T3 - 4.28 pmol/l, T4 - 13.85 pmol/l. Take Eltroxin for hypothyroidism?

TSH of 6.50 is...: A TSH level of 6.50 is too high, but there is no clear question being submitted here. If one's TSH was even higher in the past, then this would be an improvement. If one's TSH was lower in the past, then this would be a worsening. One's primary care doctor or one's endocrinologist can evaluate... and help answer the patient's true question, whatever that question might be. ...Read more

Hypothyroidism: You are already on thyroxine; meaning you are diagnosed with hypothyroidism. Under active thyroid. Your TSH is high;t3;t4 levels are low.

Likely hypothyroid,,: With a TSH likely high and a low ft4, this is likely hypothyroidism. Your temperature is low also. Fatigue and dizziness are symptoms at least in line with hypothyroidism. A positive tpo test would indicate possible hashimoto's thyroiditis or grave's disease as these antibodies are present in these conditions. Since you also have symptoms, it would be wise to see your doctor to discuss therapy. ...Read more

Let's try this...: I have only a little bit of the story you've shared. Perhaps it's time to see whether the ast and alt get back to normal after two weeks off alcohol and any not-totally-necessary meds you may be taking. If so, this is the start of a healthier life after alcohol. If not, the workup for virus infections, iron overload, wilson's, autoimmunity & need for exercise can begin. Good luck. ...Read more

4-21-14 Thyroidectomy r/t thyroiditis, goiter.  On Synthroid (thyroxine) 137 mcg- hypo s/s returning have felt great for months.  Would adding Cytomel help?

Not specific: The signs & symptoms of hypothyroidism are not specific for hypothyroidism (not a single one). Recheck your thyroid labs. If they're normal, your symptoms are due to something else. Having said that, I'm happy to do a trial of Cytomel with the Synthroid (thyroxine) in patients who want to try as long as I don't make them hyperthyroid. Some people report feeling better with comparable labs taking a little T3. ...Read more

Tsh 4.0 T3 (liothyronine) 27 T4 7.4 testosterone 58 tpo antibody 359 pregnant 7 weeks having chills no fever no overweight BMI 23 worried if something serious help?

Check with Dr.: Your tpo antibody is high, and more than a third of the women who test positive for thyroid peroxidase (tpo) antibodies while pregnant go on to develop abnormal thyroid hormone levels within two years, more followup needs to be done with these women. Your body maybe attacking your thyroid gland. This is not an emergency please do not panic and talk to your doctor. ...Read more

No: Being completely immobilized, such as bed rest, can cause elevated blood calcium because complete immobility can lead to some calcium leaving your bones and entering your blood. Normal sitting should not do this. ...Read more

Would be rare: It could make sense if your TSH was elevated due to pituitary or hypothalamic tumor. This is very unlikley. Would repeat labs. You need to include normal range as they vary from lab to lab. Looks like your ft4 and ft3 are both upper limit of normal. Usually would suppress tsh. ...Read more

I have a TSH redsult of 17.38, ft4 15.72 and ft3 4.25. Is it normal or dangerous?

You are not taking: Tsh is very sensitive to the compliance of you taking the thyroid medication. Usually, when we see a high TSH and a high t4, it means the patient took some extra thyroid meds recently. Your overall control is bad. Just take your thyroid medication regularly at the same dose and re-do the labs in a 6 weeks. Tsh level is really the long-term ft4 sensor! ...Read more

60yo, tested today: TSH (6.8 last month) went up to 10.51 and FT4 is 11.71. Why did it go up and can I wait 3 mnths to start any meds as I'm busy now?

Doesn't add up: Your TSH doesn't correlate with your FT4, Are you sure your Ft4 is 11.7? This is too high, look at the blood report one more time and let me know. Your TSH is high and if it's 10 and your Ft4 is within normal range (0.8-2.5) and you are symptom free then you have subclinical Hypothyrodism and it's time for treatment. Usually elevated TSH and Ft4 are lab error, or very rare medical conditions. ...Read more

Thyroid: Numbers alone aren't enough to work with. Do you have hypothyroidism or thyroiditis, or post thyroidectomy or none of above. Based on ft3 and ft4, i would expect your TSH to be lower. It depends on your clinical picture, lots of variables influence these #s, incl. Meds, other disorders, hormones , etc.Do you take thyroid meds? ...Read more

My TSH reamains so low (0.02) after RAI (3 years ago) even if FT4 and FT3 are normal? Does this have anything to do with the rest of my symptoms.

It depends: It depends what your symptoms are. Generally, if your TSH is low but your T4/T3 are normal then you should not worry. If you are feeling ok, then this an even better indicator. Graves disease may manifest with a low TSH but it is more important to go by your T4/T3. ...Read more

What is the definition or description of: ft4/tsh/ft3?

See answer details.: Thyroid stimulating hormone (TSH) is produced by the pituitary gland and stimulates the thyroid gland (in your neck) to produce the thyroid hormone thyroxine (t4) which is then converted into triodothyronine (t3) which is the active hormone that stimulates metabolism. Both T3 (liothyronine) and T4 are mostly bound to thyroid binding globulin, but free (unbound) amounts exist in your blood; these are ft3 and ft4. ...Read more

Depends: Lab reference ranges are set so that a few percent of healthies fall outside on either end. That being said, these are normal for most labs if the units are mcU/mL for TSH and picomoles/L for free T4 and free T3 (liothyronine). If these are the correct units, and your physician isn't concerned, relax. ...Read more

Why does TSH 3.84mu/l (ft4 15pmol/l) leap to TSH 6.49 in 20dys? Tpo & tg are ok. My mr hypophysis scan from last year is ok. Do i go for another one?

Fluctuations: The most likely cause for slightly elevated TSH with normal ft4 is "subclinical hypothyroidism". The TSH is very sensitive to minimal ft4 variations and doe there are fluctuations. However this may represent a trend towards more significant hypothyroidism, so i would repeat the test (TSH) 2 months after the second one. Repeating the MRI is unnecessary. ...Read more

At risk: With elevated TSH you are at risk for developing hypothyroidism even though based on ft 4 results you are not hypothyroid now. Your doctor may wish to put you on thyroid medication to avoid you becoming hypothyroid. At a minimum, you should retest in about 6 months. ...Read more

hyperthyroidism: The low TSH indicates that your thyroid levels are high for you, despite the normal ft4 and ft3 levels. If you had no symptoms we would call this subclinical hyperthyroidism. If your doctor feels that your symptoms are related to your thyroid, treatment would be indicated. Overall, it is reasonable to wait 4-6 weeks and repeat the levels. ...Read more

See a specialist.: Your profoundly elevated prolactin level needs to be evaluated, and your thyroid hormone levels are dangerously low. It appears there may be another problem with your pituitary gland, as it is not making TSH appropriately for the low free T4 and low normal free T3 (liothyronine) levels. I would strongly recommend you see an endocrinologist right away. ...Read more

FT4 13.9, TSH 4.64 Normal?

High FT4: "FT4" typically stands for Free T4, which has a "normal" range of 0.7 - 1.6 (or a bit higher at some laboratories), so a level of 13.9 is high. TSH of 4.64 is high normal for most laboratories. This combination is unusual but may suggest thyroid hormone resistance. The first step would be to retest TSH, Free T4, and Free T3 to confirm. ...Read more
