About Dr. Mattar

Samer Mattar, MD was introduced to modern bariatric surgery in the clinical year of my Advanced Laparoscopy Fellowship at Emory University. As a resident, Dr. Mattar did assist in bariatric cases and managed bariatric patients, but that was in the open era, and most patients were not treated in the multi-disciplinary manner that is now practiced. Outcomes were less than favorable and both mortality and morbidity rates were unacceptably high.

The advent of laparoscopy ushered in a new approach that afforded markedly reduced pain and accelerated recovery. With accrued experience, the complication rates dramatically dropped and patients presented in large numbers for these life-saving operations, resulting in a renaissance of gastric surgery and a worldwide explosion in research efforts to understand the underlying mechanisms of these life-transforming operations. As a result, bariatric and metabolic surgery now occupies a pole position in disciplines that provide the multi-disciplinary, comprehensive, holistic continuum of care that has now become commonplace in many surgical fields.

Dr. Mattar was fortunate to be “in the right place at the right time” and rode this wave of exciting innovation and scientific progress. The dramatic improvements in overall health and wellbeing that he witnessed in patients had a captivating effect on him. Over the first few years of his career, Dr. Mattar’s case distribution became progressively bariatric in nature until it entirely dominated his practice. Dr. Mattar truly believes there is no surgical specialty that so much embodies compassionate care, technical prowess, intellectual curiosity, principled advocacy, and career satisfaction as that derived from bariatric and metabolic surgery.

Dr. Mattar has had the good fortune to develop, or expand, several bariatric programs at different institutions with gratifying results in volume growth, improvement of quality outcomes and increased patient satisfaction. His style of leadership is one that promotes building bridges and achieving consensus. Because of the high burden of comorbidities that bariatric patients carry, bariatric surgery is an ideal example of the benefits that can be achieved through multi-specialty collaborative efforts in clinical care and research opportunities. These collaborative efforts at local, regional and national levels have significantly advanced this field to the benefit to patients, their families and fellow practitioners. As president of ASMBS, the world’s largest association of bariatric and metabolic surgeons, Dr. Mattar  has both participated and witnessed, from a front seat position, the remarkable advancements that have been made in the fields of patient care and pertinent patient advocacy and health policy.

Dr. Mattar has devoted his career to patient care, student, resident and fellow education, and towards raising the global awareness of the art and science of metabolic and bariatric surgery. He is confident that the most appropriate and effective approach to reversing the ravages of metabolic dysfunction can only be achieved through a holistic multi-disciplinary approach. To achieve this ideal, there must be an entity that brings together a group of experts from various specialties whose common and unifying goal is to treat the patient with metabolic syndrome; all within a unified and shared location. This patient-centric approach would best serve patients and their families, and provide consistency and longevity of therapies, and provide ample opportunities for research and innovation. 

Dr. Mattar’s ambition is to develop such a program, while exerting an emphasis towards supporting and guiding the ascending generations of motivated and hard-working surgeons and physicians who are committed to answering this most noble of callings.

About the Podcast

Reset Diabesity
Transforming diabesity together
The purpose of Reset Diabesity podcasts is to share the message about metabolic syndrome and how to manage it from a variety of expert perspectives.

Join us as we interview the world’s leading physicians, psychologists, dieticians, exercise physiologists, scientists, economists, agricultural experts, and public policy advocates in this field of diabesity.

The people we speak with will share their stories, experience, expertise, and the available and potential solutions to an out-of-control epidemic that currently affects 42% of the population and will affect nearly 50% of all Americans by the year 2030. Our goal with Reset Diabesity is to help health care professionals, future patients, and family members learn as much as possible about the disease of obesity, and the evidence-based treatments that are available.
