How much is it for a BBL? I'm 5’ 2 and weigh 174.

Hello, thanks for your question and provided information. There are many great board certified plastic surgeons that can help you to achieve your goals. The average cost for liposuction and bbl is between 3,000-3700 US$. 
Advantages:
One treatment may be all you need to reshape problem areas
Treat more areas—and larger areas—in one procedure
May be performed with either local or general anesthesia
More consistent and predictable result than noninvasive treatments
Liposuction, sometimes referred to as "lipo" by patients, slims and reshapes specific areas of the body by removing excess fat deposits and improving your body contours and proportion.
Different areas of treatment:
Thighs
Hips and buttocks
Abdomen and waist
Upper arms
Back
Inner knee
Chest area
Cheeks, chin and neck
Calves and ankles
Liposuction can be performed alone or along with other plastic surgery procedures, such as a facelift, breast reduction or a tummy tuck.
What liposuction can do?
Liposuction is not a treatment for obesity or a substitute for proper diet and exercise.
It is also not an effective treatment for cellulite—the dimpled skin that typically appears on the thighs, hips and buttocks—or loose saggy skin.

Thank you for your question. Prices vary a lot according to experience and board certification of the plastic surgeon, facilities, quality of the practice, region, etc…  Best is to have a consultation with a Board Certified Plastic Surgeon in your area to get an idea on the price. If you're willing to travel medical tourism is an attractive way to get quality results at a lower price. Cosmetic surgery in Colombia represents an increasingly attractive option for consumers looking for the ultimate combination of quality, price, availability, service, enjoyment, and value. Prices for plastic surgery procedures can be very affordable, and often 30-50% less than in the United States and Europe. However, when considering this option don’t settle for less than a Board Certified Plastic Surgeon with specialized expertise in this procedure.

Dear tamesha_brown,the cost of surgery depends on a lot of factors (type of surgery, number of treated areas, anesthesia fee, surgeon, facility fee, city, etc.). It would be the best to visit or call plastic surgery offices and ask for a price. In LA area, BBL typically ranges from 8K-12K depending on how much liposuction needs to be done to get enough fat.Daniel Barrett, MD, MHA, MS
