A local endocrinologist is a physician who is specially trained in the field of endocrinology, which is the study of hormones. If you have type 1 or type 2 diabetes, you will probably work with an endocrinologist to help you manage your blood glucose levels, understand the glycemic index and prevent diabetes-related complications. Because nutrition is such a big part of managing a chronic condition such as diabetes, a local endocrinologist can be a valuable asset to your healthcare team. They can work with your local nutritionist or registered dietitian to create an optimal health and wellness plan. Type 1 diabetes treatment includes insulin, blood sugar monitoring, diet and exercise changes and diabetes medication.
