BackgroundBariatric surgery reduces the prevalence of diabetes and improves lipid profiles. Low-density lipoprotein particle (LDL-P) is a more accurate predictor of cardiovascular events than high-density lipoprotein (HDL) and LDL cholesterol. The effects of bariatric procedures on LDL-P have not been previously reported.MethodsTwo hundred thirty patients undergoing bariatric surgery, including gastric bypass, sleeve gastrectomy, and laparoscopic adjustable gastric band placement at a single institution were included. HDL, LDL, hemoglobin A1c, and LDL-P were measured preoperatively and at 3, 6, and 12 months postoperatively. Weight was recorded at baseline and after 1 year.ResultsThere was a decrease in serum LDL-P levels, averaging 472.58 (P < .0001) over 1 year. HDL levels increased. Hemoglobin A1c and LDL levels declined. On average, patients lost 58% of excess weight.ConclusionLDL-P significantly decreased after bariatric surgery in relation to weight loss. It may be inferred that bariatric surgery decreases the risk of cardiovascular events.
