Hi I just been told I have hyperthyroidism but the question I am asking how long can you have this cause I have had symptoms on and of for a while , I have had my first blood test when I started feeling not well 11 weeks ago and just a standard CBC test then six weeks ago still feeling unwell had another test and it came back a slightly high the doctor said not to worry about it but still feeling not well . I have just spen 4 days in hospital unwell and test come back overactive the tsh came back 0.01 which I'm told is very low and t4  43.4 I think which they said is high .  I spoke to my doctor this morning and told him I have overactive th and been in hospital and his reply had been yes u have them now but ur test 6 weeks ago only showed a slight rise and would not cause symptoms like that .I think I have had this for a year on and of some days no go what so ever feeling week and the past couple of months feeling weaker no energy dizzy spells fast heart breathless headaches to the point I feel it every day ... has any one else had this where it gone undedected and got more and more worst

Thanks Gary

    I think what you describe is usual for many hyperthyroid patients.  My lab tests were only slightly off initially when I was tested but in about 3 to 4 weeks they were totally hyperthyroid.  It took my Endocrinologist about 8 weeks to complete all her testing to find the reason for the hyperthyroidism and this is important to know because hyperthyroidism can have many causes like nodules or goiters or autoimmune diseases like Graves disease or Hashimoto's thyroiditis.  It is important for you to know this.  In my case, I had Graves disease.  As well, it is important for you to learn all about your disease, lab tests and best treatments for it.  Always ask for and keep a copy of all your lab testing and learn what those values mean.  Post them to this Board if you want feedback on them.

    Yes the disease can be at subclinical levels for years until something triggers it to worsen at which point you will feel symptoms and require treatment. Hope you feel better soon.
