Patient Care

The Division of Endocrinology, Diabetes and Metabolism provides comprehensive general treatment for adults of all ages for health issues related to the endocrine system, diabetes and other metabolic conditions.

Our physicians are known as endocrinologists. Our primary focus is on diabetes, diabetes prevention, and related metabolic syndrome abnormalities such as lipid disorders and high blood pressure. We also treat other disorders of the endocrine system, such as thyroid disease, osteoporosis, pituitary dysfunction, adrenal disorders, sexual dysfunction, hirsutism, polycystic ovarian syndrome, and calcium disorders. Our newest initiative, the Treatment, Research and Education of Adipose Tissue (TREAT) Program is related to adipose tissue disorders, involving fatty tissue abnormalities that may be metabolic in nature, but differ from common obesity in that they appear to be less responsive to diet and exercise.

We offer comprehensive care and preventative health programs that include advice on nutrition, diet and exercise regimens as well as alternative therapies and surgical remedies when recommended.

Diabetes Prevention and Education Center

Our primary clinical facilities are hosted by Banner – University Medical Center (UMC) Tucson and South campuses. Banner – UMC South is the home of our endocrinology as well as diabetes patient services. On this hospital campus, the Banner – University Medicine Endocrinology and Diabetes Clinic and the Diabetes Prevention & Education Center (DPEC) are located in the Abram’s Public Health Center, 3950 S. Country Club Road, Tucson, AZ 85714.

Here, patients and members of the community are offered medical care as well as self-management support. We provide a variety of educational sessions in our demonstration kitchen, a classroom and fitness assessment facility. Our complementary programs – from diabetes support groups to classes about healthy food choices and cooking demonstrations – are offered daily and provided in both English and Spanish.
