A typical, if not inevitable, aspect of life after bariatric surgery is extra skin. Factors such as your genetic makeup, aging, the particular surgery being done and the weight you have lost all contribute to the extent to which your skin will loosen. You have many options to reduce its likelihood, which include; staying hydrated to improve your skin’s elasticity, adhering to your post-op meal plan, exercising to build muscle, or having the loose skin surgically removed.
