Lipo 360 BBL - Should I postpone my surgery until I hit my ideal weight?

Thank you for posting your question here!My answer will be based on the limited information provided, for more detailed and bespoke assessment I would encourage you to discuss with your surgeon in person.
you seem to be close enough to your goal weight , it is always best to operate on a person once they have reached their desired weight and have been stable , but in your case it is still doable since your BMI is below 30 and you are planning on undergoing a BBL as well, so I would encourage you to discuss with your surgeon so that together you guys can come up with a plan that will work for you and they can weigh in on the best timing.5 weeks should be enough to go back to work after 360 lipo with BBL but the recommendations vary amongst different surgeons and your surgeon might have some restrictions for you when you go back to work.
I hope this helps, best of luck!

I understand you’re eager to achieve your desired look with the upcoming Lipo 360 and BBL procedure. Balancing your current weight, surgical goals, and work commitments can indeed be challenging. Let’s break down your concerns:
Current Weight and Surgical Outcomes
You’re currently at a BMI of 28, weighing between 180-185 pounds, with a goal to reach 160-165 pounds. It’s generally recommended to be near your target weight before undergoing body contouring procedures like Lipo 360 and BBL. Significant weight loss after surgery can potentially affect your results, as the transferred fat may diminish with weight loss. Being at a stable, maintainable weight ensures that your surgical outcomes align with your long-term body goals. 
Returning to Work as a Flight Attendant
Planning to return to work five weeks post-op is reasonable. Many patients resume non-strenuous activities within 2-4 weeks after surgery. However, as a flight attendant, your role involves prolonged standing and minimal sitting, which can be beneficial during recovery. It’s crucial to wear compression garments and take measures to prevent swelling and blood clots during flights. Always consult with your surgeon to ensure your specific duties align with your recovery plan. 
Decision to Postpone
If reaching your goal weight is achievable in a reasonable timeframe, it might be beneficial to postpone the surgery until then. This approach can help maintain your results and reduce potential complications. However, if weight loss is gradual and your current weight is stable, proceeding as planned could also be appropriate. The key is stability; avoid significant weight fluctuations after surgery to preserve your results. 
Final Thoughts
Your health and satisfaction are paramount. Discuss your weight goals and work-related concerns with your surgeon. They can provide personalized advice, considering your unique situation, to help you make an informed decision.
Wishing you the best on your journey!
