Steady weight loss after a tummy tuck, will my skin retract and can I get lipo?

Hi, thank you for sharing your question. 
You would be a great candidate for Tummy tuck with liposuction of your flanks. If you are close to your goal weight and have a BMI around 30, you would be able to proceed. Skin retraction after tummy tuck can be unpredictable, but a healthy lifestyle will help. The best way to determine the right procedure is after a formal evaluation of your soft tissues. 
Consult with a board certified plastic surgeon to discuss your options. I hope this helps. Best of luck!

you will need a tummy tuck for the best results, with liposuction and internal heating, I would suggest BBL/braziilian butt lift fat grafting to buttock at same time.
You need a formal evaluation by an expert in body shaping and contouring to determine what is best.  Traditional liposuction awake and smart liposuction are old methods and do very poorly for tightening skin or significant skin tightening or contouring.  Small problem areas can be improved slightly by these methods.  The best in body contouring not only removes fat with energy devices like VASER ultrasound but also internally heat the skin with radio-frequency devices such as J PLASMA/RENUVION, InMode BodyTite, ThermiRF to heat the under surface of the skin and tighten it at the same time as fat removal. These combinations are called 4D HIDEF VASER contouring and can only be done by a well . trained body contouring specialist. At the same time fat should be harvested, PRP and stem cells added and injected into muscles or indentations/cellulite to get body shaping and contouring.  This is known as a Brazilian butt lift when you inject the fat to the buttock for contouring and lifting, but fat can also be used in areas such as the chest/breast, arms/shoulders, calves and face.  Cellulite should also be treated with cellfina, sculptra, subcision and/or fillers such as bellafill, renuva synthetic fat, or sculptra.  If skin is very loose before surgery then it will need to be removed such as lower abdominal skin (tummy tuck/abdominoplasty), breast skin (breast lift), arm skin (brachioplasty).  Overall you need a full assessment, but simple liposuction alone will not tighten skin and needs a combination of various methods -- fat removal, skin tightening, defining, fat grafting, skin removal -- to get the best in body contouring and body sculpting.  Dr. Emer.

I appreciate your concerns and frustrations, however you must lower your BMI to at least around 30 before considering any type of cosmetic body contouring surgery. It’s just safer! Statistics show a much higher increase of complications in patients with a BMI over 30. Choose a reasonable diet and exercise regimen to lose the weight and then consult with a board-certified plastic surgeon in your area to explore the best options for you. Good luck.
