Weight Loss Surgery


Excess Weight and Related Health problems

The prevalence of excess weight in America has more than doubled over the last 30 years, with 33% of adults currently affected. Excess weight poses a significant risk to a person’s health. The harmful effects of excess weight on health are increasingly recognized. Metabolic syndrome resulting from excessive accumulation of weight, affects many organ systems and directly impacts health through disorders like diabetes, high blood pressure, coronary artery disease, obstructive sleep apnea, and degenerative joint disease. Significantly increased weight shortens life span, and is associated with increased risk of many cancers. With its rising prevalence, excess weight will soon overtake smoking as the leading cause of preventable death in the US.



Sleeve Gastrectomy : Ideal Surgery for Excess weight

For the majority of individuals with excess weight, behavioral and medical treatments have limited long-term efficacy. On the other hand, surgery for severe obesity (known as Bariatric Surgery) produces dramatic and sustainable weight loss, and results in resolution or improvement of weight-related conditions. In a landmark study published in the New England Journal of Medicine, bariatric surgery was associated with up to 92% reduction in rate of death at 7 years, when compared to non-surgical treatments.

In 1991, a panel of experts convened at the National Institute of Health and recommended gastric procedures for individuals with excess weight, who are well informed and motivated, and have acceptable operative risks. With advancements in surgical skills and developments in laparoscopic techniques, bariatric surgery can now be performed with reduced complication rates and a one-night hospital stay.

Surgery for Severe ObesitySurgery for Severe Obesity


Every year more than 300,000 individuals in United States successfully undergo weight loss surgery and rediscover the joy of healthy living. With laparoscopic or minimally invasive bariatric surgery, one can expect to lose more than 100 lbs of weight in one year and completely resolve serious health problems like diabetes and high blood pressure.

Currently, Laparoscopic Vertical Sleeve Gastrectomy is the bariatric procedure of choice in the United States, accounting for over two third of all weight loss procedures. Dr. Zare's involvement with Sleeve Gastrectomy dates back to 2001, when the procedure was being conceptualized and developed in experimental setting at a Georgetown University affiliate hospital. As a pioneer and an early adopter of the procedure, he has successfully gathered a large volume of experience and is able to offer patients a highly refined procedure with consistently low complication rates. See below for additional information about the procedure.
