Abstract: In recent years, the prevalence of overweight/obesity in solid organ transplant recipients has been rising rapidly. Clinical research evidence on obesity in solid organ transplant recipients has been increasing, but there is a lack of standardized diagnostic and treatment guidelines and comprehensive management pathways to guide clinical practice. Based on this, the Expert Consensus on Weight Management in Overweight or Obese Adult Solid Organ Transplant Recipients (2025 Edition) was organized and written by experts from the Diabetes Professional Committee of the Chinese Research Hospital Association. This consensus mainly provides recommendations on the epidemiological data, diagnostic criteria, screening and assessment methods, management pathways, and intervention strategies for overweight/obesity in solid organ transplant recipients. It aims to further improve the management level of medical workers engaged in the whole process of organ transplantation for the population with overweight/obesity combined with solid organ transplantation, standardize clinical diagnosis and treatment, improve patient prognosis, and enhance quality of life.
