*2.2.4 Dyslipidemia*

Dyslipidemia improves with weight loss. Two meta-analyses showed improvement in serum lipids after bariatric surgery in the short term (< 3 years) [36, 37]. Studies with longer follow-up are required.

A multi-center observational study reported improvement in serum lipids with RYGB compared to baseline (14 vs. 33% for high low-density lipoprotein (LDL) cholesterol; 5 vs. 24% for high triglycerides (TG); 6 vs. 35% for low high-density lipoprotein (HDL) cholesterol) at 7 years. Other observational studies illustrated similar results [38, 39].
