I've very recently been diagnosed with Hashimotos Thyroiditis. I have been told my antibody count is high but as yet my hormone levels are normal....otherwise I've been given no further information other than what I've found via Google. I have lots of questions and still a month before I see a doctor again! Can anyone advise how long generally before my thyroid might become 'underactive'? Will I have any other issues in the meantime due to the immune system doing its stuff - I've been feeling very run down and generally unwell - migraines for much longer than normal, upset stomach, low energy. At the point I have hypothroidism will it be fully controlled with medication or will I have other issues? Apologies if I've got any of the terms wrong I am pretty much in the dark about this!
