What are the potential risks of having a Brazilian Butt Lift?
The most serious risk with a Brazilian Butt Lift is fat embolism: fat that's injected too deep can enter the gluteal veins and travel to the lungs or heart, and this is the leading cause of death associated with the procedure. That's why technique matters enormously. Fat should be placed only in the subcutaneous layer, above the gluteal muscle, never into or beneath it. A surgeon experienced in BBL will use cannula angles and injection patterns designed specifically to avoid that plane.
Beyond that, risks mirror liposuction in general: contour irregularities, asymmetry, bruising, seroma, and infection, though these are relatively uncommon. Not all transferred fat survives long-term; a portion is reabsorbed by the body, so results settle over months. Choosing a board-certified plastic surgeon who performs BBLs regularly and follows current safety protocols for cannula placement is the single biggest factor in minimizing these risks.
Clinical Context
Surgeons reduce BBL risk by using blunt-tipped cannulas and injecting fat in small amounts across multiple passes, rather than large volumes in one spot. This limits pressure buildup in the tissue and helps keep fat in the safe layer above the muscle. Ultrasound-guided or ultrasound-verified techniques are increasingly used to confirm cannula position. Choosing a surgeon trained specifically in these safety protocols matters more than the total fat volume transferred.
