After 2months of having my  thyroid removed TSH level 40, taking t4175mg, getting fat.Shall i try to combine t4&t3, in which dosages?

Need higher dose: The high TSH shows that your thyroid level is still low. 175 mcg of T4 is a relatively high dose. Your are probably not absorbing the medication correctly. You must be sure to take it on an empty stomach, wait at least 40 min before eating, do not take it with any supplements or other meds. You should be on a brand-name thyroid, such as synthroid (thyroxine) or tirosint, not generic. ...Read more

My TSH level is 4.0 but have reg periods not on any meds. Is it safe to try to conceive or is it harmful to the baby? Can I be on meds during pregn?

See Endocrinologist: If 4 is above the normal reference range for your lab, and your ft4 levels are normal, you may have 'subclinical hypothyroidism. An additional blood test to look for tpo antibodies may help your dr decide if treatment is necessary. Treatment would be levothyroxine, and at correct dose, does not harm baby. If you needed levothyroxine and did not take it, it can harm baby. ...Read more

My TSH level is 4.0 but my T3 (liothyronine) and T4 is normal. Do I still need meds? And can I be on it during pregnancy?

My TSH level is 4.0 but my T3 (liothyronine) and T4 is normal. Do I still need meds? And can I be on it during pregnancy?

See Endocrinologist: There is emerging data to suggest we should consider treating subclinical hypothyroidism if you have tpo antibodies. It's still just new evidence, and a full discussion with your endocrinologist may be helpful, especially if you fall into category of tpo negative subclinical hypothyroidism- in that case, clinical judgement and your preferences will play a larger role. ...Read more

I had early miscarriage last year, same thing happened again this year. Every report else normal. Does tsh level of 3.40 leads to early miscarriage.

I had early miscarriage last year, same thing happened again this year. Every report else normal. Does tsh level of 3.40 leads to early miscarriage.

Should not: Your TSH level is normal. Please note that about 25% of early pregnancies are lost spontaneously, due to chromosomal defects in the embryo. Losing two pregnancies is unpleasant, but it does not mean that there is anything wrong with you. Wish you good health and a healthy baby! For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. ...Read more

I was prescribed 125 mg levothyroxine by a ER dr. With a Tsh Level of 0.40 does that seem too high? (Total thyroidectomy w/parathyroid removal 11mos)

Get 2nd opinion: If the lab studies given are correct you should not need any supplemental thyroid therapy. If you have a low TSH it generally means that your thyroid is functioning at a high level. Factors to consider are why you had the thyroid removed, have you been on previous meds and has a T4, T3, (liothyronine) and Free Thyroxine been done. Have you been having any symptoms, if not, seek a second opinion before starting. ...Read more

Is a TSH level of 3.81 normal?

Depends: On who you ask. Most lab reports show normal as being 0.5 - 5 mlu/l, but many people feel the range should be 0.3 - 3. If you are being treated for hypothyroidism, the ideal range is 1 -2. I usually start to take notice when someone's TSH is >2.5. See http://www.Nlm.Nih.Gov/medlineplus/ency/article/003684.Htm. ...Read more

Tsh level is 5.69 is that high?

Tsh level is 5.69 is that high?

A little: It depends on the lab but that is just a bit elevated. Generally a lab test called free T4 is done when this borderline. If the free t 4 is low that would confirm that you are hypothyroid. When the numbers are borderline often down the road they will become frankly abnormal. If there are symptoms such as fatigue and weight gain then i would be more inclined to treat sooner then later. ...Read more
