Our Diabetes & Metabolism Research Institute brings together a broad array of diabetes expertise from multiple disciplines, all under one roof.

Highlights of our diabetes program include:


What is diabetes?

Diabetes is a disease in which the body does not produce or properly use insulin, a hormone necessary for converting dietary sugar and starches into energy. An estimated 20 million, or approximately 7 percent, of Americans have diabetes, and many more are at risk for developing the disease.

The major types of diabetes include:

  • Type 1 diabetes: formerly known as juvenile-onset or insulin-dependent diabetes, this type is an autoimmune disease in which the body's own immune system slowly destroys insulin-producing islet cells in the pancreas.
  • Type 2 diabetes: formerly known as adult-onset diabetes or insulin independent diabetes, in this type the insulin does not work effectively and is not sufficient to keep the blood sugar level normal. Thus the body's cells are unable to properly use glucose.
  • Maturity-onset Diabetes of the Young (MODY): This form of diabetes is inherited and can vary in severity. Often, MODY resembles a very mild version of type 1 diabetes with continued partial insulin production and normal insulin sensitivity.
  • Gestational diabetes: This type of diabetes develops during pregnancy in women who have never been diagnosed with diabetes, with symptoms usually occur during the second or third trimester.

Diabetes treatment options

Every patient is different, with different needs. City of Hope treats you as a valued individual. Our entire team works together to bring you precise, state-of-the-art therapy options that will deliver the best outcome for you. We support you every step of the way, helping you and your loved ones manage your condition.

Therapies we offer for patients with diabetes include:

Continuous Glucose Monitoring (CGM)

CGM devices record a patient's blood glucose continuously over several days to determine patterns and trends, providing information to your care team that can be used to better manage diabetes.

Insulin Therapy

Insulin therapy is the mainstay of type 1 diabetes treatment, and is also used in some cases of type 2 diabetes.  Recombinant human insulin is currently the standard treatment, and may be administered in several ways, such as:

  • Daily injections by the patient or caregiver
  • Insulin infusion in a hospital setting, to manage severe high blood sugar
  • Insulin pump, a wearable device that is programmed to deliver insulin accordingly to meet the patient's individual needs

At City of Hope, a diabetologist will review your medical records and meet with you to determine the best insulin administration program for your needs and goals. If you are eligible for an insulin pump, our care team will work closely with you and you loved ones to ensure that the pump is working optimally to maintain optimal blood-glucose control. This includes comprehensive education on pump operation, regular follow-up visits and 24-hour phone access for assistance using the pump.


In addition to insulin, our physicians may also prescribe other medications that can stabilize blood glucose levels, help the body better use insulin, and/or minimize risk of diabetic complications.

At City of Hope, our diabetes care team will work with the patient and caregivers to maintain optimal blood glucose control, reducing the likelihood of life-threatening episodes and the lifelong risk of diabetes-related complications, with minimal impact to quality of life.

Certified Patient Education

City of Hope employs certified diabetes nurse educators who are part of the health care team. Our diabetes educators are also registered nurses whose role is to be a teacher, counselor and coordinator of care for people with diabetes. The diabetes nurse will make sure the patient and, when possible, the patient's family or other support people understand all doctor's orders and the many aspects of the disease. This may include information about medications, how to monitor and interpret blood glucose levels, the importance of exercise, a realistic food plan, dealing with emotions, and when other health team members need to be called upon. Because diabetes is a chronic, progressive and serious disease, support over the long-term is essential to successful management.

City of Hope’s renowned physicians and researchers utilize the latest in technology and innovation to treat diabetes and other endocrine and metabolic disorders.

Living with diabetes

Diabetes and Cardiovascular Risk Reduction Program (DCVRRP)

The Department of Clinical Diabetes, Endocrinology and Metabolism offers a comprehensive, one-year medical, nutritional and behavioral management program aimed at reducing obesity associated health risks.  This is achieved through safe and consistent weight reduction of high-risk patients who are at least 30% or 50 pounds above ideal body weight and have one or more of the following medical problems: diabetes, high blood pressure, high cholesterol, sleep apnea, heart disease, polycystic ovary syndrome, disabling joint disease, chronic obstructive pulmonary disease, and/or breast cancer one-year after completion of therapy. In addition to losing weight, many patients who complete the program are able to discontinue or reduce blood pressure, cholesterol and diabetes medications.

For more information, please contact us at 626-218-2251.

Diabetes Education Program

Research clearly shows that complications of diabetes can, in many cases, be prevented if proper education and treatment are given soon after diagnosis.  For this reason, City of Hope's Department of Clinical Diabetes, Endocrinology & Metabolism is dedicated to educating and helping people with diabetes manage and take control of their disease.  The adult Diabetes Education Program is accredited by the American Diabetes Association. Participants learn:

  • Proper diet, exercise and lifestyle changes to help manage diabetes
  • Latest advances in diabetes research and treatment
  • Information to gain a better understanding of the disease, empowering each person to take control of their disease by learning self-management skills

You may be referred by your primary care physician or refer yourself by calling City of Hope.  You can also contact the diabetes nurse educator at 626-218-2251 with any questions and/or to obtain a current schedule of classes.

Sheri & Les Biller Patient and Family Resource Center

Our patients are also encouraged to take advantage of the Sheri & Les Biller Patient and Family Resource Center, which offers a wide array of support and educational services. Patients and loved ones may work with a coordinated group of social workers, psychiatrists, psychologists, patient navigators and spiritual care providers at the center, as well as participate in programs such as music therapy, meditation and many others.
