5’2”, 125lbs, 64, options for sagging arm & lower stomach after weight loss? (Photos)

Well hooray you- nice work! From what I can see, I would recommend the following:
1. Tummy tuck and liposuction of your torso
2. Add some of the liposuctioned fat to your buttocks and hips.
3. Wait a few months and you'll see that your arms will sag even more
4. An arm lift may be necessary for the loose skin in the upper arm
5. Any residual loose skin may need non-surgical skin tightening with devices such as Morpheus or Ellacor

If you can't find a board certified plastic surgeon in your area, then call our office 847-853-9900 and consider an in-person visit at some point. Best Wishes!!

Congratulations on your weight loss! In person exam is essential, as well as review of standard photos. Based on limited photos - and the history of weight loss- you may benefit from abdominoplasty and brachioplasty. I suggest that you seek an experienced Board Certified PS and review your options
