My TSH fluctuates goes to 5.5 with 12.5 mcg comes down to .27 on 25mcg. anti thyroid antibodies +ve. how to titrate.only hair loss no hypothyroid symp?

Dosing: Hi. Most systems are not that sensitive! I would suggest trying 12.5 mcg on even days of the month and 25 mcg on odd days of the mont. This will give you an average daily dose of 18.75 mcg, and should give you a nice, normal TSH. But to reiterate, most systems are not that sensitive. Make sure you're well equilibrated (dose at least 6 weeks) before testing. Good luck! ...Read more

My mom had her thyroid removed and anti bodies not thyroid antibodies have been found in her blood what does this mean? Is this life threatening?

More information: Hi. Why did she have her thyroid removed? Usually that's for thyroid cancer. EVERYONE has antibodies in their blood! If she doesn't have thyroid autoantibodies, then she didn't have autoimmune thyroid disease. If it was thyroid cancer, then not having thyroglobulin antibodies means her thyroglobulin can be followed as a tumor marker. Your statement and question is a little unclear. Care 2 clarify? ...Read more

Can you still be hypo after testing negative for thyroid antibodies? Is there something else I should be looking at? US thyroid done.

Not your thyroid: Though you did not mention this, I am assuming your doctor checked your thyroid hormone level and a TSH and that they were fine. Even if you did have thyroid antibodies, that would not make you hypothyroid but would just slightly increase the risk that you could become hypothyroid in the future. I would stop worrying about your thyroid and discuss with your doctor other causes for your symptoms ...Read more
