When you gain weight over a long period of time, your skin expands around your growing body. After weight loss surgery, you may lose in excess of 40 to 70 kilograms. As a result, your skin usually doesn’t have enough elasticity to recover from the prolonged extensive stretching. This may leave you with excess, sagging skin and residual fat. This excess skin often results in more than just cosmetic issues. It can prevent you from fully enjoying your healthier life.

It may result in:

  • Postural problems 
  • Chafing, and rashes, especially when it rubs against other folds of skin or when it stays moist Infections, as loose skin creates folds that are harder to clean, and chafing causes breaks in your skin, paving the way for infections
  • Unpleasant body odour due to moisture trapped in skin folds
  • Body-confidence issues due to embarrassing or uncomfortable folds of redundant skin

There are many ways to reduce the amount of loose skin you may develop after surgery including:

  • Balanced diet with plenty of protein and vitamins
  • Exercise
  • Cosmetic surgery (if none of the above are enough)

A balanced diet: 

Eating sufficient protein may help you build and maintain lean muscle. It may also help to improve your skin elasticity, so it can fit more tightly to your new frame. After bariatric surgery, it’s important to eat at least 60 – 100 mg of protein a day. Taking your prescribed multivitamins may also preserve some skin elasticity after weight loss surgery. Vitamins C, A, E, K, and B-complex vitamins, as well as trace minerals such as zinc, are all important for skin health.


Exercise can limit the amount of loose skin you may develop after bariatric surgery. When you prevent the loss of lean muscle mass, you reduce the looseness of your skin. When you gain muscle, you actually fill out your skin more.


Doing all of the above will help, but the fact is that after losing 40 to 60 kilograms, it is realistic to expect that you will still have some excess skin. There is a range of surgical procedures that for the treatment of excess skin in the most commonly affected areas, which include the upper arms, back, breasts, abdomen and thighs. Together these excess skin and fat reduction surgeries are often known as body contouring surgery. They are only recommended after 18 months once your weight has plateaued.
