One of the common questions I hear from patients is whether they will gain weight as a result of buttock augmentation. In order to answer this question, let me explain that there are two types of butt augmentation procedures: fat transfer to the butt (more popularly known as Brazilian butt lift) and butt implant surgery. As the name suggests, fat transfer to the butt involves the use of your own body fat to enhance your buttocks. During the procedure, excess fat from your body areas like the abdomen, sides, flanks, things, and upper back are removed, purified, and grafted into your buttocks. You will not gain weight as a result of the fat transfer procedure because it simply involves changing the site of the fat, i.e. transferring the fat from the fat donor sites to the butt. Instead, your weight may decrease mildly as a result of the removal of the impurities, dead or injured fat cells, and fluids during the fat processing. When it comes to butt implant surgery, the procedure involves the use of foreign objects called gluteal implants to deliver the desired results. Unlike fat transfer surgery, it does not involve the use of your own body tissue. As a result, you may expect to experience some weight gain. The increase in your weight will be equal to the weight of the implants. The weight gain after butt implant surgery will not be substantial enough to make a huge difference. For example, 100 cc butt implant weigh around 100 grams. This means that when you get two implants of 400 cc, you will gain a total weight of about 800 grams. The weight gain resulting from butt implant will be concentrated in your butt. Initially, it may feel like you have gained more weight, but you will adjust to it and everything will seem normal within a few weeks. To conclude, you will not gain any weight as a result of the fat transfer procedure. In the case of butt implant surgery, you will gain minor weight in your butt.
