Losing weight is a goal for a large portion of the people in our society. Unfortunately not all of the side effects of weight loss are desirable. The biggest complaint most people have after weight loss is the extra loose skin that is left behind. Skin gets stretched with pregnancy and weight gain to the point that it cannot recover. Its elasticity is shot and it will not contract back again to its original size/shape. Further weight loss actually accentuates the problem. Depending on the amount of weight lost, that loose skin can be quite extensive and far in excess of what any non-invasive or minimally invasive external treatments can correct. After major weight loss it is almost always necessary to undergo a skin removal procedure such as a tummy tuck, thigh lift or brachioplasty depending on the site(s) of excess skin.
The best advice to anyone who has had a major weight loss and is now stuck with excess skin is to be evaluated by a Board Certified Plastic Surgeon who can fully assess the situation and guide you to the proper treatment that will accomplish your goals.
