Lost Weight = Loose Skin
If our jeans hang loose when we lose weight, it would make sense that our skin would as well. In cases of moderate weight loss, our skin shrinks back to fit the body's new size, thanks to its elasticity. A protein called collagen in the skin gives it this special property, which helps explain how we don't outgrow our skin as we get older. But as we age, these collagen fibers in the skin do weaken, leading to wrinkles.
Collagen does have its limits. Rapid growth or weight gain can outpace collagen production in the skin, causing areas to overstretch. This can lead to striations called stretch marks. These are particularly common with pregnancy and adolescents going through puberty. Although several lotions and creams on the market claim to get rid of stretch marks, most naturally go away on their own.
Sometimes in cases of massive weight loss, people have folds of extra skin left over from their heavier days. Their skin had become so outstretched that it hangs limply from the thinner body, like worn out elastic.
As the number of obese people undergoing gastric bypass surgery increases, so do corrective surgeries for the unwanted and often uncomfortable loose skin. Although it may seem purely cosmetic, extra skin can actually cause infections, rashes and back problems. Since it's a highly invasive procedure, plastic surgeons may space out skin tucks and removals over months or a year. A tummy tuck costs $5,798, on average, according to 2016 stats from the American Society of Plastic Surgeons. That figure does not include the cost of anesthesia and operating room facilities or other expenses.
Even after the work is done, patients wear lifelong scars from the surgeries. Also, this type of body recontouring comes with risks. Since it's a relatively new procedure, doctors only know anecdotal evidence of complications, including dead skin, infection and open wounds [source: Singer]. But as beltlines continue to bulge, the numbers of patients will likely increase as it has the past decade.
