Hello, Five months ago I suffered some high blood pressure and bit fatigue, my test results was: -TSH 0.005 , Free T3 3.2, Free T4 1.27, Ab 42.6, Anti TPO 150 - Neck Altra sound : thyroid glands size ok, all normal except increased vascularity allover thyroid gland parenchyma - All test results was fine, CBC, alt, ast, sodium, potassium. MR brain ok. I treated my sinus , teeth route canal(as I read it could be related to TPO) , done regular exercise and I was fine till now with no blood pressure and good health. Just this week felt little bit fatigue and slight throat discomfort, I though its better to make a new test and exams, outcome was : -TSH 0.005, free T3 4.41, free T4 1.38. Ab 99, Anti TPO 297 -TC99m PERTECHNETATE Thyroid scan : Thyroid uptake 6.2%, Thyroid with no substernal activity seen, intense and uniform radio tracer uptake is visualized allover the gland with no sizable intra-thyroidal focal lesions should be seen, the extra thyroidal background activity and salivary glands uptake are diminished due to increased avidity of thyroid gland for the tracer. - Throat Sputum exam : Gram positive cocci,, puss cells moderate , culture : mixed growth staph aureus and strept pyogen  I have taken Antibiotic Averozolid Questions if you please : 1-     Your opinion. 2-     Do I have Graves disease ? despite haven’t got any of its sever symptoms. 3-     High TPO could be related to throat bacteria ? 4-     Is there is a relation between Sinus and TSH low level? 5-     Can I avoid taking Thyroid medicine ? (I don’t take any regular medication). 6-     Is it possible to try first natural nutrition to lower my T3 ? 7-     Not sure whether iodune food substances are good to lower the T3 or not ? as I read different directions about iodune diet Many thanks for your fine cooperation and apology if I was bit long or specific Regards, Amr Madany
