(CNN) - According to the American Society for Metabolic and Bariatric Surgery, more than 220,000 people had surgery last year to help them lose weight. But for some of these patients, dropping the excess fat was only half the battle.
When Sarah Beth Daken was in her twenties, she started to gain weight, and by the time she was in her thirties, she weighed over 300 pounds.
Frustrated and worried about her weight, she decided to get lap band surgery in 2008.
"One of the pitfalls of having that much weight is that when you lose it, you have all this excess skin," Daken said.
She chose to have plastic surgery, known as body contouring. It's a procedure where doctors remove excess skin, sometimes up to 20 pounds of it, from people who have lost a lot of body fat.
"We've had very good techniques over the years as we've gained experience in this area, in really hiding these scars in areas underneath underwear, or bathing suit lines, or under a bra line," said Dr. Joseph Michaels with Monarch Aesthetic and Reconstructive Plastic Surgery.
Although the surgery can help with most areas of the body, Michaels said the stomach and upper arms seem to be the main concern.
"Another common area is the breasts, as well as the buttock and back region," he said.
As with all surgeries, there are risks and it can take weeks to heal.
The procedure is not covered by insurance, but many patients who've transformed themselves due to weight loss don't think they're complete until their bodies reflect the way they feel.
So to some, like Daken, the expense is very worth it.
