Detailed answer

When someone loses a significant amount of weight, the skin may not have enough time to adjust to the new body shape, resulting in sagging skin. This is because the skin stretches with weight gain, and when the weight is rapidly lost, the skin may not retract fully. Factors such as age, genetics, overall health, and the amount of weight lost can also influence skin elasticity. It's important to note that not everyone who loses weight will experience sagging skin, but it is a possibility. Staying hydrated, maintaining a healthy diet, and exercising regularly can help improve skin elasticity and minimize sagging.
