Hello, and thank you for your questions regarding the fact that you require arm lift surgery, but you still have weight to lose, and do you have to wait until you hit your goal weight before arm surgery. Thank you for your history and your arm pictures. Your case is why every plastic surgeon should treat patients as individuals. The classic plastic surgery teaching says that a patient should lose as much weight as possible and be stable at that weight for three months before embarking upon reconstructive plastic surgery after significant weight loss. You may have an ideal body weight or a BMI of less than 30. Therefore, classically, plastic surgeons recommend you lose all your weight before embarking upon your arm reduction, arm lift, or brachioplasty. However, most experienced plastic surgeons would recommend that you have your arm lift now. Several things support this opinion, including your age, the extent of your arm anatomy, geographic location, hot climate, and wishing to go outside by the pool. Also, you mentioned that further weight loss is slowing down. Not to be discouraged, but it may be very difficult for you to reach your goal weight. Therefore, I recommend you have your arm surgery now. Even if you lose further weight, it is doubtful you would need a revision. However, this isn't very certain. Therefore, you will get the best results if you lose as much weight as possible before your arm lift or brachioplasty. If, however, you are frustrated with the situation based on your age, a significant amount of excess arm skin, arm fat, being in a hot climate, and wishing to go outside by the pool are all indications that you can undergo your arm surgery before reaching your ideal body weight. You must also realize that you will not get the best result if you undergo a brachioplasty before reaching your goal weight. However, you will get adequate arm lift results. Good luck. I hope I've answered your question regarding the fact that you require arm lift surgery, but you still have weight to lose, and do you have to wait until you hit your goal weight before arm surgery. I hope that I have answered your questions regarding the arm reduction. If you have any more questions regarding the arm lift, arm reduction, brachioplasty, or arm crease fat grafting, please get in touch with an arm lift expert. Since a brachioplasty or arm lift surgery is difficult, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of arm lifts. Do your research. Make sure your chosen plastic surgeon has performed at least 100 arm lifts. Make sure they have the before and after pictures to prove it. Carefully examine their before and after pictures and check their reviews on RealSelf. Sincerely, Dr. Katzen.
