Table 4 Changes in blood lipids before and after laparoscopic gastric bypass surgery (mean ± SD)

	Preoperative (n)	5 years after surgery (n)	P value
TG (mmol/L)	2.1 ± 1.9 (36)	1.2 ± 0.7 (36)a	0.037
CHO (mmol/L)	4.5 ± 0.9 (36)	4.3 ± 0.7 (36)	0.504
HDL (mmol/L)	1.1 ± 0.3 (35)	1.4 ± 0.3 (36)a	0.001
LDL (mmol/L)	2.8 ± 0.6 (36)	2.6 ± 0.6 (36)	0.336

^aP < 0.05, the differences were statistically significant when compared with the preoperative period.

TG: Triglycerides; CHO: Total cholesterol; HDL: High-density lipoprotein; LDL: Low-density lipoprotein.
