Profile of the obese patients submitted to Roux-en-Y gastric bypass whithout diabetes melittus type 2 remission and/or insufficient weight loss.

Background: The literature reports that gastrojejunal derivation with Roux-en-Y gastric bypass is highly efficient in controlling weight and resolving; but studies have shown worsened glycemic control in a considerable number of patients and associated factors that have not been fully elucidated.

Aim: To analyze the profile of patients submitted to gastric bypass that did not achieve satisfactory weight loss or complete diabetes remission.

Methods: Case-control study of 32 patients submitted to gastric bypass with at least two years postoperative time, unsatisfactory results in terms of weight loss or absence of complete diabetes remission.

[Insufficient loss of weight and/or absence of DM2 remission after Roux-en-Y gastric bypass: factors that may influence the unsatisfactory results].

Background: Roux-en-Y gastric by-pass is considered one of the most effective treatments for maintaining long-term weight loss. However, it is associated to failures manifested by the inability to maintain weight loss, weight gain or poor glycemic control.

Objective: Study the possible factors that influence weight loss failure and/or DM2 remission.
