The major focus of Dr. Gletsu Miller's laboratory is to study nutritional status in obesity and following weight loss intervention. One research project is interested in improving nutritional health following bariatric surgery. Bariatric surgery is a common and highly effective treatment for severe obesity, but patients are at risk for nutritional complications, including deficiencies in iron, copper and vitamin D. Objectives of this research are to describe the prevalence of nutrient deficiencies, the mechanisms involved, the clinical consequences, and to develop effective treatment strategies. Another research project is interested in identifying dietary and physical activity behaviors that contribute to the development of type 2 diabetes in adolescents who are obese. This project utilizes innovative tools to objectively measure diet and physical activity. The goals of this project are to identify problematic dietary and physical activity factors that can be targeted in behavior modification interventions for the prevention of type 2 diabetes.
