Excess skin after weight loss, also known as loose skin, is a common concern for many individuals who have lost a significant amount of weight. It occurs when the skin has stretched to accommodate a larger body size and then has difficulty shrinking back to its original size after weight loss. Loose skin can be a source of discomfort and self-consciousness for some people, and it can also lead to skin infections and other health problems.
There are a number of factors that can contribute to the development of excess skin after weight loss, including the amount of weight lost, the rate at which weight is lost, and the age of the individual. Younger individuals tend to have more elastic skin that can snap back more easily after weight loss, while older individuals may have less elastic skin that is more likely to sag. Additionally, people who lose weight very quickly are more likely to develop loose skin than those who lose weight gradually.
