Liposuctioned fat comes back in all the wrong places, says study


Liposuctioned fat comes back in all the wrong places, says study

What the surgeon’s knife takes, seems like nature gives you right back.

According to new research out of the University of Colorado, liposuction patients who had fat deposits removed from one part of their body were shocked to find new fat deposits appearing elsewhere. In the studied cases, researchers looked at non-obese women who had the fat sucked out of their thighs and lower abdomens.

Fast forward one year, and the fat all came back in the upper body, particularly in the upper abdomen, shoulders and triceps of the arms.

Liposuction, which typically involves injecting large amounts of medicated fluid into fat deposits, then sucking the fluid and the fat out of the body, is primarily a cosmetic procedure. It is not a treatment for general obesity. And it has side effects too, including shock, infections, uneven appearance and scarring.

But that hasn’t blunted its popularity. Americans underwent around 200,000 liposuction produces last year, making it the fourth most popular form of cosmetic surgery, according to the American Society of Plastic Surgeons.

The idea of a quick shot to remove ugly fat deposits is so alluring that more than half the women in the control group of the study (the ones who didn’t have the surgery for the first year) opted to have it anyway even after hearing that their counterparts had already gained the fat back in odd places.

“It’s another chapter in the ‘You can’t fool Mother Nature’ story,'” Dr. Rudolph Leibel, an obesity researcher at Columbia University who was not part of the study, told the New York Times.

The research appeared in the journal Obesity:

Abstract

No randomized studies in humans have examined whether fat returns after removal or where it returns. We undertook a prospective, randomized-controlled trial of suction lipectomy in nonobese women to determine if adipose tissue (AT) is defended and if so, the anatomic pattern of redistribution. Healthy women with disproportionate AT depots (lower abdomen, hips, or thighs) were enrolled. Baseline body composition measurements included dual-energy X-ray absorptiometry (DXA) (a priori primary outcome), abdominal/limb circumferences, subcutaneous skinfold thickness, and magnetic resonance imaging (MRI) (torso/thighs). Participants (n = 32; 36 ± 1 year) were randomized to small-volume liposuction (n = 14, mean BMI: 24 ± 2 kg/m2) or control (n=18, mean BMI: 25 ± 2) following baseline. Surgery group participants underwent liposuction within 2–4 weeks. Identical measurements were repeated at 6 weeks, 6 months, and 1 year later. Participants agreed not to make lifestyle changes while enrolled. Between-group differences were adjusted for baseline level of the outcome variable. After 6 weeks, percent body fat (%BF) by DXA was decreased by 2.1% in the lipectomy group and by 0.28% in the control group (adjusted difference (AD): ?1.82%; 95% confidence interval (CI): ?2.79% to ?0.85%; P = 0.0002). This difference was smaller at 6 months, and by 1 year was no longer significant (0.59% (control) vs. ?0.41% (lipectomy); AD: ?1.00%; CI: ?2.65 to 0.64; P = 0.23). AT reaccumulated differently across various sites. After 1 year the thigh region remained reduced (0.77% (control) vs. ?1.83% (lipectomy); AD: ?2.59%; CI: ?3.91 to ?1.28; P = 0.0001), but AT reaccumulated in the abdominal region (0.64% (control) vs. 0.42% (lipectomy); AD: ?0.22; CI: ?2.35 to 1.91; P = 0.84). Following suction lipectomy, BF was restored and redistributed from the thigh to the abdomen.
