Can I gain weight for round 2 BBL?

You are in good company with many others who had high hopes for BBL but instead received disappointing results (lumpiness, unevenness, lack of projection in the central and/or lower buttock, etc.). It is not quite as much the quality of the doctor but rather the quality of the procedure that is a large part of the problem. Thus, going back for round 2 BBL most often produces the same disappointing results but at another financial loss. Buttock implants indeed provide a more reliable, predictable, relatively safe, and permanent result, especially for adding projection to the buttock and often smoothing out lumpiness. Please keep in mind that an extremely few number of board-certified plastic surgeons specialize in buttock implants so be sure to consult with one that is reputable and experienced. Unfortunately you may have to travel long and far away from home to find this particular surgeon. Glad to help.

Having the BBL done a second time is an option as long as you have enough fat to be transferred. The revision implies that there is less fat than the first time, and scar tissue will make the surgery much more difficult on the surgeon. The percentage of fat survival in the BBL the second time should be about the same.
Gaining weight is often counterproductive. If you gain weight that is fat, some of the fat will likely be associated with the buttocks. In almost every case, I do not recommend weight gain prior to a BBL. I think it is better to maintain your stable weight.

Dear hawkinsindia,
generally speaking, you want to reach your goal weight before you consider a surgery, otherwise your results will be suboptimal if you continue to lose weight after the surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Personally I do not recommend anybody gain weight for the purpose of having fat transfer procedures. Based on your picture your bottom is already substantial and making it even larger will make you look like a caricature.

I suggest following up with your provider and discussing your concerns with him or her.

Best,
