Re-emergence of diabetes after gastric bypass in patients with mid- to long-term follow-up

Our results have shown that beyond 3 years after RYGB, the incidence of T2DM recurrence or worsening in patients with initial resolution or improvement was significant. In our patients, a greater likelihood of recurrence or worsening of T2DM was associated with a lower preoperative body mass index. Before widespread acceptance of bariatric surgery as a definitive treatment for those with T2DM can be achieved, additional study of this recurrence phenomenon is indicated.
