Regardless of the weight loss method, there is a risk of skin laxity when weight loss is too rapid, especially with weight loss metabolic surgery. Because weight loss metabolic surgery is more efficient, and people who choose this way to lose weight have a large weight base, the skin expands a lot, and a lot of people’s skin collagen fibers have started to break and lose their elasticity, so they are very prone to the problem of sagging skin. However, human skin has good elasticity, and mothers like those who had a large waistline when they were pregnant were able to recover after giving birth, so it is just as easy to prevent or reduce the problem of sagging skin by taking the right approach after weight loss metabolic surgery. Before we operate on patients, nutrition is assessed and post-operative nutritional guidance is formulated according to the surgical plan to ensure that the patient’s nutritional needs are met. After the patient is discharged from the hospital, the health manager will also give guidance on exercise, telling the patient how to exercise and how long to exercise, together with the nutritionist’s guidance to help the patient regain skin elasticity, those patients with good compliance and not a large weight base can basically avoid the problem of skin laxity. Those patients with a high weight base and more weight loss, due to rapid weight change, it is difficult to completely avoid skin laxity with diet and exercise alone, and can only be relieved to a certain extent with reasonable post-operative guidance, but can also be slowly restored through diet and exercise in the future, and if skin laxity is too serious, you can also choose dermatoplasty surgery to repair it.
