Purpose: Many studies about bariatric surgery have analyzed the effect of sleeve gastrectomy (SG) on glucose improvement, beta-cell mass, and islet size modification. The effects of SG on the other endocrine cells of the pancreas, such as the alpha-cell population, and their regulatory mechanisms remain less studied.
Materials And Methods: We focused our work on the changes in the alpha-cell population after SG in a healthy model of Wistar rats.
