Results of an endocrine follow-up of obese pre-diabetic and diabetic patients before and after bariatric surgery, through an evaluation of nutritional and biochemical variables, analyzed 14, 28, 42 and 56 days after surgery at Uberlândia-Mg, Brazil

This prospective study included 22 women undergoing RYGB, of which 6 had pre-diabetes,
and 1 was diabetic. The team consisted of an endocrinologist, a surgeon, a nutritionist
and a psychologist. Anthropometric, nutritional and biochemical parameters were analyzed
preoperatively and 14, 28, 42 and 56 days after surgery. Specifically, 4 goals were
set: 1) to describe the presence of morbidities associated with obesity, and their
evolution after surgery; 2) to study the alterations in the biochemical variables
after the RYGB proceeding; 3) to evaluate the nutritional changes related with the
pre- and post-surgery times; and 4) to follow the changes in body mass index (BMI)
and weight loss during pre- and post-surgery, on 4 different time lapses after surgery.
