This finding is called “The obesity paradox” and there are lots of papers trying to explain why obesity can increase survival in these patients. Adipose tissue secretes some cytokines involved in metabolic pathways and inflammation, also in dialysis patients. Chronic kidney disease is related with a chronic inflammatory status and a high risk of weight loss and malnutrition.
