I'm 5'3" and weigh 195 lb, am I too big to get a tummy tuck and BBL?

Having photos would allow me to make a better assessment.  The BMI of 34.5 computed from your weight and height indicates that you would not currently be a candidate for a TT and BBL.  Losing 25 pounds would decrease the risk of complications during and after surgery and would lead to optimal results. You want to be at a long term stable weight before the TT is performed.  Otherwise, a revision may be required.  Weight is not the only indicator of candidacy; your health history and current health must be evaluated.I would search for the board certified plastic surgeon who you feel is most likely to give you the best results and who performs hundreds of TT and BBL combinations each year. I would look at patient reviews as well as before and after photos on that surgeon's website. Then schedule a virtual consultation (it's typically free) with the plastic surgeon to discuss the path to reach your goals.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Thanks for the question. To avoid unnecessary risks we recommend body mass index equal or less than 30 for perform surgery. I recommend you to send a photo to us to give you advices of what you should/shouldnt perform. In case that you want to loss weight before the procedure i recommend you to go to a nutritionist to loss it in a proper way. Kind regards 

Although you will likely be a good candidate for tummy tuck surgery at some point, it is not in your best interests to proceed now.  Having the procedure performed when you are overweight, exposes you to additional risk around the time of surgery and increases your risk that additional surgery may be necessary down the line for a multitude of reasons.  Unfortunately, some of the risks (such as deep venous thrombosis and pulmonary embolism) associated with surgery, can be life-threatening. 
In my practice, I do not ask specific patients to achieve a specific weight prior to proceeding with tummy tuck surgery. I simply ask patients to achieve a long-term stable weight where he/she feels comfortable and does not expect significant fluctuation postoperatively.
The “ideal” patient for tummy tuck surgery is one who has completed pregnancies, is psycho socially/emotionally/financially stable, has an excellent social support system surrounding him/her, is capable of arranging enough recovery time, does not smoke and who has reached a long-term stable weight. 
At this point, I would suggest that you  seek consultation with other professionals,  other than plastic surgeons.  Physicians who specialize in weight loss, nutritionists, personal trainers, and/or bariatric surgeons are professionals to consider.  
 I hope this helps.
