The hourglass hip procedure involves the use of your own body fat to widen your hips. During the surgery, the excess fat from your abdomen, sides, and flanks is removed, which results in a smaller waist. The fat removed from the body is processed and purified and then injected into the hips and butt. As a result of the fat grafting, the butt becomes fuller and the hips become wider. One of the concerns of patients considering the hourglass hip procedure is how weight loss will affect the achieved aesthetic outcomes. When the fat is grafted into the hips and butt, your body takes some time to establish blood flow to the fat cells. After 2-3 weeks, the new fat cells in the butt and hips would be vascularized, meaning your body will establish connections with them. After vascularization, the fat cells transferred to the butt and hips will start behaving exactly the same way as the fat cells in other areas of your body. In simple terms, it means your body would treat the fat cells the same way as it treats the fat in other areas of your body. Weight loss will affect the fat in the hips and butt the same way as it does the fat in other areas of the body. This means weight loss can lead to shrinkage of the fat cells in the hips and butt. As a result, the hips may lose its width, and the butt may lose its fullness. Fortunately, you can avoid the effects of weight loss on the results of the hourglass hip procedure by choosing an experienced plastic surgeon to perform the operation. If the fat cells are properly and carefully extracted, purified, and grafted into the hips and butt, the effects of weight loss on the achieved results can be minimized. Moreover, patients are advised to keep a stable weight and avoid weight loss after the hourglass hip procedure. You should be sure to eat healthy and balanced diet after the procedure and closely monitor and control the changes in your weight.
