Diabetes and Obesity Specialist Internal Medicine

Dr. Nachida Hamidi-Sitouah is a Diabetologist and Obesity specialist certified by the American Board of Obesity Medicine and the American Board of Internal Medicine.

After completing her internal medicine residency and working as an academic hospitalist in New York for three years, Dr. S moved to Greenville North Carolina and worked as a primary care physician at a community health clinic.

Driven by her clinical interest in Diabetes and Obesity and her passion to educate and empower her patients for maintaining healthy lifestyles, Dr. S completed a Diabetes and Metabolism Fellowship at East Carolina University. She then wrote a book called “Diabetes for Primary Care: A Step-by-Step Approach”.

As a Diabetes specialist, she realized the impact of weight on Diabetes and multiple other diseases, and that the best way to improve outcomes for most of her patients was to treat the source: excess weight. This journey led her to pursue Obesity Medicine Certification and to expand her knowledge in this field.

Dr. S established her practice by focusing on prevention. In this practice, in addition to providing diabetes management services for patients with Type 1 and Type 2 Diabetes, Dr. S runs a dedicated weight loss clinic, committed to helping patients with and without Diabetes reach their weight and health goals.
