What kind of clearance do you need before getting a BBL? Is this something you need from PCP or PS?

I have high blood pressure and has been under control for over a year. I wanted to get myself prepared before my consultation and surgery early. I had my blood work done a few months ago for a an abdominal hysterectomy and everything seems to be fine except my triglyerides is slightly elevated and my Vitamin D was low. I now take a Vitamin D supplement daily at 2,000 IU. Everything else is normal. I'm also 43 years old, 5'5, and 180lbs. Looking to get 1,000 cc or more per buttock. Thanks!
