Hi there
@Speedbird,
Yes the two illnesses are both autoimmune diseases. I have both! The thyroid illness only became apparent after 10 years of seeking an answer. I had the operation, (a week after a hysterectomy) because it was wrongly diagnosed as a gynaecological problem. A visiting Doctor diagnosed HyperThyroidism the week after my hysterectomy!! I had a scan at the Brompton Hospital, and my thyroid was glowing!! The next week I had the operation. I was 'sorted' pretty quickly, as far as I remember. It was a relief not to have a pulse equivalent to doing aerobics when just sitting. It made a lot of difference for good.
The only problem was, 10 years later (whilst taking oral thyroxin) symptoms returned, (apparently it can grow back because the thyroid is tied into ones vocal cords, and the operation cannot remove it all without risk to your speech) , so I then opted for radioactive iodine treatment, and this killed the thyroid. Now taking oral thyroxin for 20 years. Diagnosed diabetic last February 2016.
Hope all goes well for you. I'm sure you will feel better, particularly if the levels are very high. All the very best
