I have a big butt (A-shape) and somewhat wide hips, but how much can the width of my hip increase with BBL? (Photo)

Thank you for your question. It seems like your a candidate for a BBL (Brazilian butt lift). This includes liposuction from unwanted areas of fat with transfer to the hip and glute area to sculpt your desired shape. The amount of transfer will be dependent on the amount of fat that can be removed, and how much retains after the procedure (about 60%). I would recommend a consultation with a board certified plastic surgeon to discuss your goals. Best of luck!

This is all a question of balance and proportions.  Fat can be taken from many different areas of the body including abdomen, sides, back, bra rolls, thighs, arms, underarms, etc.   You have to consider not only which areas will have perhaps the best fat, but also you have to consider which donor sites will have the fewest problems afterward with the liposuction.  In general, the abdomen and thighs are preferred, but, if those sites are not available, other areas can be used.  Creative liposuction with fat transfer to the hips can make them appear lifted, and rounder.  If the waist was smaller at one time, the waist can likely be reduced to those same measurements or smaller provided the muscular and fascial integrity has remained the same.

Thank you for your question.The increase in the width of your hips will depend on the amount of fat available and your body structure. It is more important, however, to improve the proportion between the waist and the hips. Removing the fat from the waist area and injecting it into the hip area will achieve this. Please consult a Board Certified Plastic Surgeon who can help you with your concerns. All The Best !

More pictures of your backside would be helpful. If you have a nice apple shaped backside and want to increase the perception of width sometimes all you need to do is to decrease the width of your hips through liposuction.

The one picture isn't enough info to make an informed recommendation, but reshaping of the buttocks with combination liposuction and grafting to targeted areas is definitely possible. Just make sure that you and your plastic surgeon are crystal clear about the shape that you're going for before proceeding with the surgery.If you are a good candidate for a Brazilian Butt Lift (BBL), the optimal outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. These three processes have demonstrated over 95% fat graft take. This means that your results will be stable as long as you maintain your weight. As an official VASER trainer, I am routinely referred unhappy BBL patients. One of the most common reasons for disgruntled BBL patients is that patients are not able to accurately communicate their desired buttocks goals to their surgeons.  A buttocks assessment tool can be an invaluable tool to communicate to your surgeon the exact buttocks size and shape you are desiring. A Skype or FaceTime consultation with a BBL specialist can help you get an accurate recommendation and pricing.
