Keep in mind that each patient is unique and your results may vary.
This is a 30 year old woman requesting tummy tuck and liposuction for the waistline. She had a tremendous amount of loose abdominal skin after giving birth and was quite upset with her appearance in a bathing suit. She said it stopped her from wearing any number of fashions, but was particularly difficult for her to choose a bathing suit. The tummy tuck removed her loose skin and tightened her abdominal muscles leaving her with the tummy of a young girl as if she had never had children. This is unusual, but not completely out of the question for someone after weight loss. I am now working on some follow up studies to demonstrate women who have had pregnancy after their tummy tuck. I'm finding that revisions are rarely necessary.
