Hashimotos with Antithyroglobulin of 4000 (normal is 116)

Over the past few years I have gone to 2 dieticians and twice to my GP about excessive weight gain. They've always tested the normal blood sugar levels, cholesterol, vit D and so on, but (to my knowledge) never my thyroid function or thyroid antibodies and then, when the diets don’t work, just told me that I am not exercising hard enough. Last week I went to the doctor for a standard sore throat when he felt a lump on my thyroid. He immediately sent me for a sonar which showed that there was indeed a lump, but it's not malignant. Thereafter he did blood tests for Thyroid Function and Thyroid Antibodies. The blood tests came back showing that my Antithyroglobulin (Thyroid Antibodies) level is 4000 IU/ml (normal is 116 IU/ml), Antithyroid Peroxidase is 70 IU/ml (normal is 10 IU/ml). TSH is normal. Free T4 is normal. The doctor said this confirmed that I definitely have Hashimoto Thyroiditis, but because the thyroid antibody level is so high, I need to wait until my thyroid "burns out" completely before I can start with any medication. In the mean time I just need to go back for blood tests in 6 months. I sent these results to another doctor just to make sure, and sadly he said the same. My question: Is it normal to just sit and wait for my thyroid to become completely inactive before taking any action. This means that it might still take a very long time before I can do anything about my weight and from what I've read many other complications can come from a "burnt out" thyroid. Should I just follow the doctors advice and wait while my body keeps attacking itself or does anybody know if anything I can do? Any help will be appreciated :)

Wow! I did not expect to get a reply so quickly! THANK YOU!

Other test results:
TSH (Beckman) Result: 1.50 mIU/l Reference: 0.20 - 3.5
Free T4 (Beckman) Result: 11.5 pmol/l Reference: 7.7 - 16.9

Other symptoms:
Tired most of the time
The muscles in my neck and back tense up very quickly and I regularly go the physio to have it sorted out.
Cholesterol level is high (Sorry, I dont have the results with me)
Blood sugar levels were high (I was told that I am insulin resistant at some stage, but the last test showed that my blood sugar levels are normal again)
Depressed from time to time. I was told that this was from a vitamin D deficiency, but even after drinking a supplement I dont really feel much better.
It often feels like my throat is swollen, kind of the same sensation as being strangled.
Blurry vision at times and seeing sparkles even when not looking into the sun

I'm not sure which of these symptons really relate to thyroid problems, but those are all the "problems" that I am experiencing.

Thanks again!

Thank you so much! It already helps to know that there is someome else who also thinks that just waiting is a bad idea. It sounds a bit odd, but is that is the best thing to do right now, then I'll do it :)
