Although physiological contributing to loss body weight improvements obesity-related comorbidities are incompletely understood, complexities neurohormonal precise mechanisms resulting durable associated continue be elucidated. Even though we learn progress understanding intricate interplay between alimentary tract axis, benefits clear well-documented with long-term follow-up results surgery demonstrating mortality morbidity significantly reduced.
