Female, 38, why does my butt look like this after weight gain and will this procedure fix it? (Photo)

Hi! thanks for your question. The changes in your buttocks after weight gain, like sagging or unevenness, can be due to increased fat accumulation and skin stretching. When you gain weight, fat can redistribute unevenly, especially in areas that have been previously treated or are more prone to fat storage. The procedure you're considering could help, depending on what it is. For example, a fat transfer, liposuction, or skin-tightening treatment could improve the shape and address sagging. A thorough evaluation with a plastic surgeon would help determine the best approach for your case.

Thank you for posting your question here!
I will start by stating that the answer is based on the limited information and pictures provided , for a more bespoke plan please consult with your plastic surgeon.
the skin and underlying tissues are usually held in place by ligaments and fibrous bands that connects those tissues to the underlying fascia, moreover each person is unique in terms of their fat distribution. Weight gain and the increase of fat in certain locations can lead to deformities due to the increase tension on those ligaments and bands, in addition to making any abnormal fat distribution more pronounced.
weight loss can in most cases help in reducing those deformities , but if that is not an option for you for any reason , this can also be corrected surgically by redistributing the fat and taking down certain ligaments .
I hope this helps, best of luck!

Increase of fat tissue volume in many other areas of human body would create secondary deformity. Loss of weight is the best way to correct this problem; in some cases surgical intervention may help. N person or teleconference with a board certified plastic surgeon may give you some answers.
