I am 23 years old, I weight 270 lbs and I am 5’4. Can I get lipo and BBL only at my current weight?

Thanks for your question. Your safety is of utmost importance to us. We never want to do anything that might jeopardize our patient's health. Unfortunately, based on the measurements your BMI is 46.3, making you ineligible for cosmetic surgery at this time. High BMI poses high surgical risk and reduces the likelihood you will receive optimal cosmetic results. Patients considering cosmetic surgery should have a BMI closer to 30 in order to minimize risks and to maximize results. 
If you have been unable to reach your goal weight with diet and exercise we recommend you schedule a consultation with a Board Certified Bariatric Surgeon. This option might be the best next step for you in terms of getting your body ready for cosmetic surgery in the future.

Hello dear!
Thanks for the question and provided information as well.
Unfortunately, right now your BMI is 46 and it needs to be 33 or less, for you to be considered a good candidate for plastic surgery.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and the best options for you.
Good luck :)
