Massive weight loss, am I candidate for a tummy tuck revision? (photos)

Based in your photos you are candidate to enhance some more your results.
You have excess of the width of your abdominal skin and have those attachments on the sides of the belly button which make the saggy skin more obvious.
So you will be a great candidate to convert your TT into a Fleur de Lis-Lower body lift, which means to do the vertical incision in the midline to remove the excess of width, thake advantage and do a tight muscle repair to create a flatter abdomen and smaller waist and have some shape. The circumferential incision will be to perform the buttocks lift and I would add some liposuction to the back and waist to add curves and transfer a bit of fat to buttocks. Your mons would be revised during the procedure.
Your breast is beyond third degree saggy and will need a major breast lift-reconstruction, possibly augmentation, plus you will be candidate also for lateral torsoplasty, back lift to achieve a smooth and feminine back and possibly an arm lift.
As expert in the After Weight Loss surgeries, the upper body lift should be done in a separated stage from the Lower body lift, 6 months later.
Be encouraged!!! You have already achieved a remarkable improvement Losing the weight.

Dear Raebay86,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Congratulations on your weight loss! From your photos it does appear you are a candidate for a tummy tuck revision. Liposuction can be added for further contouring of the area. Typically you will want to wait 9-12 months from your last surgery before considering the revision to allow the tissues to heal and settle.
