Background: Although effective, the impact of bariatric surgery on weight loss is variable, and little is known about the influence of single-nucleotide polymorphisms (SNPs). The present study investigated the association of eleven SNPs related to obesity with weight loss 1 year after Roux-Y gastric bypass (RYGB) surgery in female patients.
Methods: This prospective study included 351 women with obesity.
Article Synopsis
- - The study examined how food intake affects weight loss and the role of specific gene polymorphisms one year after Roux-en-Y gastric bypass surgery in 95 obese women aged 20-50.
- - Researchers measured body metrics and food consumption before and one year post-surgery, and analyzed 12 gene polymorphisms, but found no significant differences in food intake between quartiles of weight loss.
- - Overall, the study concluded that neither the estimates of energy or macronutrient intake nor the examined gene variants predicted significant body weight loss 1 year after the surgery.
Objective: Obesity can cause systemic arterial hypertension (SAH) and type 2 diabetes mellitus (DM2) factor that is also influenced by genetic variability. The present study aims to investigate the association between gene polymorphisms related with obesity on the prevalence of SAH and DM2 in the preoperative period and 1 year after Roux-en-Y gastric bypass surgery.
Subjects And Methods: In total, 351 obese women in a Brazilian cohort completed the study.
Background: Low-grade chronic inflammation in morbid obesity is associated with impaired iron metabolism. Bariatric surgery is effective in weight loss; however, it can induce specific nutritional deficiencies, such as iron, especially in premenopausal women. Alternatively, after surgery, there is an improvement in systemic inflammation, raising questions concerning the dosages of micronutrient supplementation.

Aim: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery.
Restricted food intake after bariatric surgery can be an important factor both in the long-term control of body weight and in the onset of nutritional deficiencies. The objective of this study was to assess the adequacy of food intake in women two or more years after bariatric surgery according to the excess weight lost. A group of 141 women who underwent banded Roux-en-Y gastric bypass (RYGB) was divided according to the percentage of excess weight they lost (%EWL)<50; 50┤75; = 75.

Hence, the objective of this work was to characterize the prevalence, the associated factors and the list of food aversions with the effect of surgery on the body weight of women in the first two years after Roux-en-Y gastric bypass. A total of 141 women were studied.

Subjects And Method: A total of 141 women underwent banded Roux-en-Y gastric bypass (RYGB). The participants were divided according to the time elapsed since surgery and the percentage of excess weight lost (%EWL): < 50; 50 upper and lower left quadrants 75; and > 75.
