Why does the fat disappear after a brazilian butt lift?

17th Jan 2020

 

The Brazilian butt lift is a procedure that uses the patient’s own fat tissue to get a moderate increase in the size of the buttocks and also a perky effect of the butt. The surgery is more and more in demand nowadays as it is safe and efficient and the results can be sustained long-term easily.

The Brazilian butt lift is actually a combination of liposuction with fat transfer to the butt. This means that the plastic surgeon will perform liposuction on areas with a surplus of fat, process the fat, and then reinject it into the buttocks. The areas targeted with liposuction need to provide enough fat for the transfer. This means that it is often the flanks, abdominal wall, thighs and back that are targeted. By performing liposuction on these areas, the patient will get an overall improved body shape, aside from a perky, bigger butt. 

After liposuction is performed, the fat extracted needs to be processed to eliminate the blood, other impurities, and damaged fat cells from the mix. The purification process is actually centrifugation. After purification, the healthy fat cells are injected into the buttocks with special syringes. The injections need to be done in different areas of the buttocks and at different depths to ensure the survival of most of the fat cells transferred.

It is normal for a certain percentage of the fat injected to disappear from the buttocks in the first two to three months post-op. This happens as the fat is reabsorbed by the body. The fat can disappear from the butt in the first weeks or months post-BBL also because the patient didn’t follow the recommendations of the plastic surgeon. Smoking can cause the death of the fat cells, and sitting or lying on the buttocks can also lead to the same result. This is why the instruction is to refrain from smoking long enough to give the fat cells transferred to the buttocks an opportunity to develop a new blood network that will ensure their survival in the area. Smoking leads to a lack of proper oxygenation, and this is essential for the fat cells to survive after the transfer. Also, sitting on the buttocks too soon after the procedure can lead to the death of the fat cells and their reabsorption. Lying on the back and sitting directly on the buttocks needs to be avoided for a minimum of three to five weeks post-op and even more, depending on the recommendations of the plastic surgeon. 

A percentage of no more than 30 to 40% of fat is normal to be reabsorbed by the body in the first months post-op until the fat transferred develops a new blood network. To ensure most of the fat transferred survives, the patient needs to be careful and follow the recommendations of the plastic surgeon to the letter.
