Endocrinology, Diabetes & Metabolism

The endocrine system is a complex collection of hormone-producing glands that control basic body functions such as metabolism, growth and energy. The amount of hormone produced by each gland is precisely balanced: too much or too little of a hormone can create serious effects throughout the body.

Successfully diagnosing and treating the resulting endocrine conditions is what our board-certified physicians specialize in. Our experienced endocrinologists use today’s most successful therapies to treat a wide variety of disorders affecting the thyroid, adrenal glands, pituitary gland, pancreas, lipid disorders, growth hormone assessments, and bones (including osteoporosis and vitamin D deficiencies).

Our participation in promising new research helps ensure we bring the latest evidence-based medicine to the care of each patient. Through our active involvement in clinical trials, we are able to offer patients the latest improvements in medications and therapies.

Our comprehensive approach includes several innovative programs designed to improve the health and quality of life of our patients:

  • Medical Weight Loss Program: designed and supervised by our endocrinologists to help patients lose anywhere from 10 to 100 pounds, Healthy Concepts is creating dramatic health benefits for hundreds of patients
  • Comprehensive diabetes education: our certified diabetes educators and registered nutritionists offer a four-week small group class to help you effectively manage your diabetes
  • Insulin pump therapy: using an insulin pump requires more work, but results in better diabetes control and more freedom. A highly trained nurse practitioner—certified in insulin infusion—offers education and support to help patients choosing insulin pump therapy succeed

And because St. Jude Heritage Medical Group includes virtually every specialty, whatever additional care or services you might need—from cardiology and gastroenterology to surgery— you’ll find the necessary expertise right here.
