Dr. Naji Abumrad's clinical interests cover all aspects of general surgery and, particularly, endocrine surgery. His extensive research activities include studies of the mechanism of insulin resistance in the morbidly obese, and in particular, he is conducting studies related to the understanding of the mechanisms involved in the reversal of type 2 diabetes in morbidly obese patients who undergo bariatric surgical procedures. Additional studies carried out in his laboratory, address the metabolic effects of opioid peptides and opiate alkaloids; and in particular cocaine on energy metabolism and fuel mobilization. Dr. Abumrad's work has been funded by NIH grants during most of his academic career.
