Weight loss, adverse events, and loss to follow-up after gastric bypass in young versus older adults: A Scandinavian Obesity Surgery Registry study

Outpatient Weight Loss Surgery: Initiating a Gastric Bypass and Gastric Banding Ambulatory Weight Loss Surgery Center

BACKGROUND Ambulatory surgery or outpatient surgery is becoming increasingly common. In 2002, 63% of all operations performed in the United States were ambulatory procedures. Bariatric procedures performed in the United States have increased from 16,200 in 1992 to approximately 205,000 in 2007. In 2002, our center began offering laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures on an out...

Body composition assessment in extreme obesity and after massive weight loss induced by gastric bypass surgery.

Body composition methods were examined in 20 women [body mass index (BMI) 48.7 +/- 8.8 kg/m(2)] before and after weight loss [-44.8 +/- 14.6 (SD) kg] after gastric bypass (GBP) surgery. The reference method, a three-compartment (3C) model using body density by air displacement plethysmography and total body water (TBW) by H(2)18O dilution (3C-H(2)18O), showed a decrease in percent body fat (%BF...

Weight Loss and Heart Failure: A Nationwide Study of Gastric Bypass Surgery Versus Intensive Lifestyle Treatment

Mechanisms of weight loss after gastric bypass and gastric banding.

The obesity epidemic is a major health problem that is associated with increased morbidity and mortality. Gastrointestinal hormones have been increasingly understood to be an important element in appetite regulation. Several gastrointestinal hormones can contribute to obesity by modulating the activity of the gut-brain axis. Bariatric surgery is currently the most effective therapy for signific...

Assessing Alterations in Food Preference as a Mechanism Contributing to Weight Loss after Gastric Bypass Surgery

Roux-en-Y gastric bypass (RYGB) surgery is a very successful option for the management of obesity, and our understanding of how this intervention mediates sustained weight loss continues to grow. Controversy exists regarding whether bariatric surgical procedures such as RYGB may modulate food preferences of individuals, in particular, reducing appetitive and consummatory behaviour toward dietar...
