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. ...Read more

Do i need treatment if my TSH 7.69 high normal free T4 and free T3 (liothyronine) and elevated thyroid antibodies?

Do i need  treatment if my TSH 7.69 high normal  free T4 and free T3 (liothyronine) and elevated thyroid antibodies?

Yes: Tsh 7.69 with high tpo is not "high normal" but high and indicates hypothyroidism. Having high tpo indicates autoimmune or hashimoto's thyroiditis. I suggest adding selenium zinc b complex and vitamin c and iodine and avoiding gluten for a month and rechecking levels in a month. If no change then you might need thyroid supplementation. ...Read more

My blood results came back normal but I still don't feel right? Tests for thyroid, antibodies, low test (TSH, T4, T3) and testicular. Physically

My blood results came back normal but I still don't feel right? Tests for thyroid, antibodies, low test (TSH, T4, T3) and testicular. Physically

Work with your team: When people just don't feel right in a general way, blood tests such as you had rarely give the answer. You need to find a provider (either MD or NP) who will listen to your complaints, get more history, and not just order tests. Perhaps you are not getting enough sleep or have some form of depression or mood disorder. Lots to consider and you need to see someone for more than 10-15 minutes ...Read more
