A new study suggests that women who have liposuction to trim their tummies may gain some fat deeper within the abdomen — a type of fat that’s particularly unhealthy.
Brazilian researchers found that within months of abdominal liposuction, there may be an increase in the so-called visceral fat that surrounds the abdominal organs.
But the good news, they say, is that regular exercise may prevent that deep fat from forming.
Fat is not “inert tissue,” said study leader Fabiana Benatti of the University of Sao Paulo.
“Removing it by surgery may have important consequences, such as the compensatory growth of visceral fat,” Benatti said.
Visceral fat is particularly undesirable because it’s more closely connected to the risks of Type 2 diabetes and heart disease, versus superficial abdominal fat just under the skin.
The study, according to Benatti’s team, appears to be the first to give “compelling evidence” that visceral fat builds up after liposuction — at least if you don’t exercise.
The findings are based on 36 normal-weight women who had liposuction to take away a small amount of superficial tummy fat. All had been sedentary before the procedure.
Four months later, the study found, women who had remained sedentary still had flatter tummies but were showing a gain in visceral fat — a 10 percent increase, on average.
Screening for violence beneficial
Doctors should screen all female patients for signs of partner violence, either face-to-face or through a waiting room questionnaire, a new report suggests.
The review of screening for partner abuse, from researchers at Oregon Health & Science University in Portland, is the first step toward new recommendations on screening from the government-sponsored U.S. Preventive Services Task Force.
According to the Centers for Disease Control and Prevention, nearly 3 in 10 U.S. women have experienced rape, stalking or physical violence by a partner. Other studies suggest that 50 percent of women will experience psychological aggression from an intimate partner at some point in their lives.
In the new analysis, researchers found the harmful effects of screening — women feeling uncomfortable or depressed — are small, and the potential benefits include catching cases of past or current partner violence and referring women for help.
