Patient Stories

Patient Stories: Evan Nadler

Sabrina Teaser

Sabrina's Story

At just 13 years old, Sabrina had already exhausted the endless list of weight-loss diets and programs that had promised her “real” results. And to her ever-deepening frustration and despair, nothing was working.


Renesha's Story

When Renesha came to Children's at 19-years-old, she weighed 286 pounds. Now, after her treatment through the Obesity Institute, she's a self-proclaimed "health freak," encouraging her family and friends to work out and eat healthy with her.


Maria's Journey

Maria was the first patient to have weight-loss surgery at Children's National. With its multidisciplinary approach, a team developed a personalized plan for the teenager.



A Game Changer for Detecting Complications From Obesity

There is a direct relationship between the amount of visceral adipose, or belly fat, a person has and development of some of the most common and life-threatening complications of obesity, including cardiovascular disease and the insulin resistance that leads to diabetes. What remained unclear, until recently, were the precise mechanisms for how the increase in belly fat triggers the onset of additional disease.
