The Brazilian Butt Lift (BBL) procedure carries several potential risks. Some of the most significant include fat embolism, where fat enters the bloodstream and can block the lungs, causing life-threatening complications. Other risks include blood clots, cardiac complications, infection, nerve damage leading to numbness or tingling, bruising, skin discoloration, swelling, poor wound healing, scarring, and asymmetrical results. It is essential to consult with an experienced surgeon to minimize these risks, as they can often be reduced with the proper technique and post-operative care, such as wearing a compression garment and avoiding direct contact with the buttocks during recovery. Additionally, the risks related to liposuction—used in BBL to harvest fat—also apply, such as contour irregularities, seroma, or excessive blood loss. Fat necrosis (the death of fat cells), lumpiness, or firmness in the injected area is another concern. It's important to have a thorough discussion with your surgeon to understand all potential risks and ensure you are prepared. Working with an experienced surgeon who understands the complexities of BBL can help mitigate many of these risks, ensuring the safest outcome possible.
