Bariatric surgery leads to greater improvements in lipid profiles (increased HDL, decreased triglycerides) compared to non-surgical treatment, while LDL and total cholesterol changes are not significantly different.

Bariatric surgery improves lipid profiles by significantly increasing HDL ('good') cholesterol and decreasing Triglycerides compared to medical management. While LDL cholesterol may not change significantly, the overall improvement in lipid markers contributes to reduced cardiovascular risk. Patients should view lipid improvement as one of the key benefits of surgery alongside glycemic control.

Bariatric surgery acquired more decrease of triglycerides compared with non-surgical treatment for T2DM (MD = -51.27, 95%CI: -74.13 to -28.41, P < 0.0001)... Bariatric surgery acquired higher increase of HDL cholesterol compared with non-surgical treatment for T2DM (MD = 9.07, 95%CI: 7.60 to 10.55, P < 0.00001)... Change of LDL cholesterol was no significantly different between the two groups (MD = -13.69, 95%CI: -41.14 to 13.77, P = 0.33).
