Hyperthyroid not Graves disease?

I have a hyperthyroid yet Dr says not Graves I have shadow around one side of thyroid he mentiond scaring all af this to a jonior Dr not to me he saw this on an ultra sound scan I am a very calm person and would just like to know what other conditions cause your thyroid to go over active can anyone give me genuine advice

Ok... To be blunt: 3 major causes of hyperthyroidism are:

1- Graves Disease (auto immune disease)
2-Toxic Multinodular goitre
3-Adenoma.

What you have sounds to be an adenoma. If it was toxic multinodular goitre... then there would be more than one mass. Since there was only one mass... the liklihood is that you have an adenoma which is a tumour that produces excessive T3 and T4 (thyroxine). These are normally benign tumours (meaning they are not cancerous), but there is a small percentage that is.

I should add that without seeing you and the test results it is difficult to say what exactly you have (i.e. the exact cause of the hyperthyroidism). There are many other causes, but I have stated the three most common. A previous person mentioned excess iodine in the diet and this is a viable cause, although in your case unlikely.

Good luck and i wish you best. I hope this answers your question.

I had a hyperactive thyroid when I was younger, dr said it was fairly common for young people to have a hyperactive thyroid. Mine went away on its own after about a year with no medication and hasn't come back (that was 8 years ago).

I know that it has to do something with excess Iodine, sometimes when you eat Iodine rich foods. But mine was unexplained.

If you have other hormones that are not within normal ranges it may have something to do with your pituitary gland so you should get them checked out as well

i had hyperthyroidism when i was in my early/mid twenties and had to have surgery to remove it but it came back about 8 years later but carbimazol worked that time. i was told that it was just one of those things with no particular cause, although iodine deficiency, not over exposure can play a part. the worst thing for me was the palpitations, i truly thought my heart was going to beat through my ribs at times.
