Thank you for your question regarding whether there is a BMI requirement for an arm lift. There isn't a specific BMI requirement for an arm lift. However, it's typically recommended that your BMI is less than 30 for any surgical procedure. This guideline helps minimize your anesthetic and surgical risks of complications. However, arm surgery can still be performed if your BMI is higher. It's crucial to choose a plastic surgeon who is well-versed and experienced in arm lift surgeries. Seek a plastic surgeon with a significant number of before and after pictures in their photo gallery, demonstrating their expertise. I hope this effectively answers your question regarding BMI requirements for an arm lift, arm reduction, or brachioplasty. Thank you. Sincerely, Dr. Katzen
