Absolutely your thyroid could be affecting your blood sugar levels. If your thyroid is not working properly, your adrenals are having to compensate for what the thyroid cannot do. Mercury also affects the adrenals, causing a decrease in production of cortisol, which is responsible for, among other things, regulating blood sugar. Do you have a constant fluey feeling? This is low cortisol, and a sign your adrenals are underproducing. I am hypothyroid, hypoadrenal and have major problems controlling my blood sugar.

It is unlikely that you have diabetes - it is probably hypoglycemia. You need to eat a high protein diet (protein with every meal) and low GI food every four hours to control blood sugar levels. Don't eat sugary things! - this will make it worse. You may also need adrenal support. Google on hypothyroidism and hypoglycemia to find other links, but on this forum all the people have problems with thyroid, adrenals and blood sugar, and you can learn a lot.

Hypothyroidism, hypoadrenalism and hypoglycemia are the three main symptoms of amalgam illness, as identified by Dr Andy Cutler. This is what I have. I hate to say it, but you sound like you may have it too. I guess chelating is the only way out, but in the short term you can make symptoms better by supporting the thyroid and adrenals.

Hope this helps.
