Abstract:Diabetic gastrointestinal neuropathy（DGN）is one of the prevalent and severe chronic complications of diabetes mellitus， characterized by gastrointestinal motility disorders and impaired secretory and absorptive functions. These disturbances often result in refractory malnutrition，weight loss，and unstable glycemic control，thereby establishing a persistent vicious cycle. The prevalence of DGN is increasing steadily，positioning it as a significant clinical challenge that adversely affects patient health and long-term outcomes. Due to the nonspecific nature of its early clinical manifestations，DGN is frequently underdiagnosed，leading to delayed or inappropriate interventions. At present，understanding of the underlying pathophysiological mechanisms remains limited，and standardized diagnostic and therapeutic protocols are lacking，contributing to suboptimal clinical management. This expert recommendation addresses key clinical problems of DGN by elucidating its pathophysiology，advocating for early recognition and accurate diagnosis，and outlining comprehensive management strategies. It aims to provide evidence - based guidance to enhance the prevention and treatment of DGN，facilitate disease modification，and ultimately improve patients’quality of life and long-term prognosis.
