A local endocrinologist is a doctor who has studied and trained in endocrinology (the study of hormones). A local endocrinologist diagnoses and treats diseases that affect people’s hormones and associated glands. Patients with type 1 or type 2 diabetes, metabolic syndrome, hyperthyroidism or hypothyroidism and cholesterol disorders often work with a local endocrinologist. If your local family physician feels that you need to see a local endocrinologist, they may refer you to one. Your local family physician and endocrinologist may work together to help you manage your condition and prevent complications.
