Excessive wasting after dialysis for kidney disease is considered as malnutrition, which is a common complication in maintenance hemodialysis patients, often secondary to insufficient nutritional intake, excessive loss, increased protein catabolism; other consumptive diseases such as tumors and so on. 1. Malnutrition: it often occurs when there is insufficient intake, such as overly strict dietary control, reduced food intake on hemodialysis days, excessive loss, such as gastrointestinal blood loss, loss of nitrogenous substances in dialysis, and increased protein catabolism, such as metabolic acidosis, parathyroid hyperplasia, and so on. 2. Consumptive diseases: such as various malignant tumors, severe infections, tuberculosis and other diseases leading to increased nutritional consumption causing excessive wasting. For those who suffer from excessive wasting after dialysis for kidney disease, it is recommended to visit the hospital in time, clarify the cause of the disease under the doctor’s guidance, and give appropriate dialysis and treatment plan after evaluation.
