Study Shows Fat Removed by Liposuction Returns to Other Places

Liposuction, which has been around since 1974, has been offered as an alternative to women who either want fat removed from a particular part of their body or who have dieted to their ideal weight but still carry more in areas such as their thighs or the “saddlebag” zone. There are over 450,000 procedures performed a year “each costing a few thousand dollars”, according to the New York Times.

Search liposuction information websites and you can read familiar responses to questions about whether fat removal is permanent. They typically say that fat cells removed by liposuction are permanently removed. Fat cells that are still present at the liposuction area can grow larger but no new ones will form. Generalized weight gain will evenly distributes itself proportionately all over your new body layout.

However, a new study from University of Colorado by Drs. Teri L Hernadez and Robert H. Eckel has disproved the concept that fat removed by liposuction is truly gone. It may be gone from the site it was removed from but the body, seeking its normal balance, will replace those lost fat cells in other places.

The study, published in the latest issue of “Obesity”, tested 32 non-obese women--14 had liposuction and 18 women acted as the control group but did not have liposuction performed. The women who were used as the controls were offered an opportunity to have liposuction performed after the study was completed if they still wanted it at a discount. All the women were instructed to maintain their current lifestyle throughout the study.

The researchers took measurements at six weeks, six months and at one year of the percent of fat each group had lost. They found that initially the liposuction women had lost 2.1 percent of their fat while the control group only lost .28 percent. However, at the end of the year there was no significant difference between the two groups. It was determined that the liposuction women had regained their lost thigh fat but it had reappeared instead--mainly in their abdomen with lesser amounts in the upper arms and shoulders.

So, the explanation that liposuction permanently removes fat is only partially correct. True, the fat cells are gone from the site they were removed and do not re-grow however, the body compensates by just making new fat cells in a new location. It is thought that the reason the fat cells cannot return to the original liposuctioned area is due to the fact that the fishnet structure the fat was secured in had been disrupted by the action of the procedure.

Even with this new information, it is unlikely that women will suddenly start turning away from liposuction. Overall, the women in the test group were happy with their new liposuctioned bodies and despite knowing the results of the study, most of the control group women still opted to have their liposuctions performed afterwards.
