If you lose a lot of weight, it will significantly reduces your disease risk.
But people who achieve major weight loss are often left with a lot of loose skin, which may negatively affect appearance and quality of life.
What Causes Loose Skin After Weight Loss?
Skin is the largest organ in your body and forms a protective barrier against the environment.
The innermost layer of your skin consists of proteins, including collagen and elastin. Collagen, which makes up 80% of your skin’s structure, provides firmness and strength. Elastin provides elasticity and helps your skin stay tight.
During weight gain, skin expands to make room for increased growth in the abdomen and other parts of the body. Pregnancy is one example of this expansion.
Skin expansion during pregnancy occurs over a few months’ time, and the expanded skin typically retracts within several months of the baby’s birth.
By contrast, most overweight and obese people carry extra weight for years, often beginning as early as childhood or adolescence.
