Will having high cholesterol put me at high risk for complications when having lipo and BBL?

Thanks for your question.
No, it should not affect your surgery or recovery. But, it should be addressed in your pre-operative work-up. 
Please always consult with a board certified plastic surgeon.
Take care,

Generally, an elevated cholesterol level slightly put you at a higher risk for any surgical procedure including BBL and lipo. However, cholesterol level is a single value, there are other aspects of your health that collectively can tell how much is your risk for the surgery.
