This is not a simple question to answer without more information. Have you lost weight? How much weight have you lost? Have you had gastric bypass? What is your height? If you have lost a significant amount of weight, i.e. more than 100 pounds, are approximately one year out from your gastric bypass, and your weight is stable, I would say "yes", you can proceed with an armlift or more accurately, an arm reduction. The procedure arm lift or arm reduction is also called a brachioplasty. Typically, an arm reduction or brachioplasty is covered by most medical insurance plans. the procedure takes approximately 2 to 3 hours under general anesthesia. The recovery time is approximately one week. If you have not lost a significant amount of weight, not had gastric bypass, if your weight fluctuates, and if you are less than 5'8", I would say "no"; you should not have an arm lift or arm reduction. If this is your case, I would suggest losing weight. Once your weight has been stable for three months, then I would suggest seeking a board-certified experienced plastic surgeon specializing in massive weight loss patients with significant experience in arm reductions or brachioplasties. I hope this helps to clarify your situation. Good luck with your weight-loss journey.
