"People who have had significant weight loss are coming to grips with dealing with [their bodies]," said surgeon David Reath, a member of the American Society of Plastic Surgeons. "Whether they've lost weight through weight reduction surgery or diet and exercise, if they were overweight for a long period, the
skin hangs around, and it’s very demoralizing. They're looking for a solution."
One solution appears to be a procedure called an upper arm lift, which involves either liposuction or brachioplasty, a surgery that removes loose skin is removed from the back of the arms.
Plus, "anytime we start talking about arms the image of the buff First Lady comes into mind," Reath said.
