[Changes in bone metabolism markers in women after Roux-en-Y gastric bypass].

Evaluation of markers for calcium homeostasis in a population of obese adults undergoing gastric bypass operations.

BACKGROUND Gastric bypass operation has become a very common procedure for treatment of obesity. Changes in calcium absorption can result in changes in total body calcium, parathyroid hormone (PTH), and vitamin D levels. There is little known about the longterm effects of Roux-en-Y gastric bypass on calcium metabolism and bone homeostasis. STUDY DESIGN Between January 2000 and January 2006, 5...

True fractional calcium absorption is decreased after Roux-en-Y gastric bypass surgery.

OBJECTIVE Roux-en-Y gastric bypass (RYGB) is considered to be the gold standard alternative treatment for severe obesity. Weight loss after RYGB results primarily from decreased food intake. Inadequate calcium (Ca) intake and metabolic bone disease can occur after gastric bypass. To our knowledge, whether malabsorption of Ca contributes to an altered Ca metabolism in the RYGB patient has not be...

Effect of Roux-en Y gastric bypass on bone metabolism in patients with morbid obesity: Mansoura experiences.

BACKGROUND Roux-en-Y gastric bypass (RYGBP) has been found to be the most efficient way to lose weight and maintain the weight loss in morbid obesity. However, with the formation of a new stomach and the modification of intestinal anatomy, there are significant changes on bone metabolism. The objectives of this study were to evaluate effects of weight loss on bone metabolism after Roux-en Y gas...

Comparison of roux-en-y gastric bypass techniques with and without distal gastric plication in patients with morbid obesity

Liver markers, prevalence of the metabolic syndrome abnormalities and effect of Roux-en-Y gastric bypass in morbidly obese subjects.

OBJECTIVES To evaluate the relations between liver markers (GGT, ALT and AST) and the metabolic syndrome (and its components) in morbidly obese subjects, and to determine the response of these metabolic factors and hepatic enzymes after weight loss induced by Roux-en-Y gastric bypass. METHODS This study was carried out at a university hospital, in Santo André (SP), Brazil. We evaluated 140 mo...
