It's great to get an endocrinologist because they do additional things over a GP. For instance a manual exam of the thyroid, ultrasound of the thyroid, fine tuning of the thyroid meds, monitoring of the diabetes, knowledge of all the diabetic meds available, knowledge of the interactions of the liver with the thyroid and the diabetes. A knowledge of nutrition that involves the liver, thyroid and your diabetes.. good luck with your new doctors.
