This study had as its main objective to assess the variation in body weight of patients on peritoneal dialysis (DP) during the first year of treatment and as a secondary goal to identify patients with criteria for metabolic syndrome (SM). Observational study conducted with 35 patients of a university hospital. Data were collected on the clinical and demographic status, change of body weight and criteria for SM from the sample. After 12 months of initiation of dialysis, approximately 40% of patients showed overweight and/or obesity. The average variation of body weight after one year was 3.7 Kg, and the largest variation was found in the first three months, with values of 2.2 Kg. The prevalence of SM was 30%. It was concluded that the most important change of body weight happened in the first year of treatment and there is a high prevalence of SM in patients on DP.
