How long ago did you?

Answer 1

How long ago did you start the thyroid medication? What is the thyroid medication? It often takes time for thyroid medications to work. In the meantime, an overactive thyroid(hyperthyroid) speeds up the metabolism in the body. That means that insulin and other substances are processed, broken down, and excreted faster than normal. That is the reason that your blood sugar is still high. Do not increase your dose of diabetic medications without consulting your physician though, because when the thyroid medication starts to work, you will be taking too much of your Diabetes medications. The short answer to your question is, yes, it is common for your blood sugar to still be high.
