Gastric Bypass Surgery & Ghrelin Hormone

A study in this week's New England Journal of Medicine reports that ghrelin could play a key role in long-term weight regulation.

A team at the Veterans Affairs Puget Sound Healthcare System and the University of Washington compared blood samples of 13 obese subjects, before and after six months on a low-fat, low-calorie diet, with those of five patients who had undergone gastric bypass surgery.

While dieters lost 17 percent of their body weight, their ghrelin levels simultaneously rose by 24 percent. In contrast, gastric bypass patients dropped 36 percent of their body weight yet saw their ghrelin levels plummet 72 percent lower than those in the diet group.

 

Scientists believe that ghrelin is a cause of hunger.

Weight Loss Surgery - No Guarantees
Gastrointestinal weight loss surgery is not an easy weight loss option. It's a serious surgical procedure whose long-term weight loss success depends on a patient's commitment to diet and behavior modification for life, along with exercise for weight control.
