Detailed answer

Sagging skin can be a result of rapid weight loss. When you lose a significant amount of weight quickly, the skin may not have enough time to shrink and tighten to the new body shape. This can lead to sagging skin. Additionally, rapid weight loss can cause a loss of collagen and elastin, proteins that provide elasticity to the skin. Collagen and elastin depletion can further contribute to sagging skin. It's important to note that factors such as age, genetics, and overall skin health can also influence the severity of sagging skin after weight loss. Regular exercise, staying hydrated, and maintaining a healthy diet can help improve skin elasticity and minimize sagging.
