Sagging fat or skin after weight loss; how do I get rid of it and improve belly button shape? (photos)

Excellent question. Often when individuals undergo a significant weight loss there is residual skin that does not contract back down as one would expect. This is often due to the inherent loss of skins elasticity. There are some minimally invasive procedures which do have some mild skin tightening associated with them but they are often under powered to provide the level of correction people are looking for. Often a surgical excision of the skin redundancy is required.I would suggest a consultation with a Plastic Surgeon who can go over what option best suits your needs.

Congratulations on your weight loss! It is difficult to tell
without personally evaluating you, but people who have especially slack skin in
their midsection and abdominal muscle weakness need more than what diet and
exercise alone can offer. Typical candidates for a full tummy tuck are women
with drooping abdomens after pregnancy, women and men who've lost a great deal
of weight, menopausal women, or older people with loose skin due to age. In the
tummy tuck, the skin from the rib cage down to the pelvic area is tightened,
and the navel is moved up and secured in a new position.
A mini-tummy tuck is especially effective for people who look pretty good from
the navel up. The main difference between the 2 procedures is that the
mini-tummy tuck doesn't require moving or reconstructing the navel and the
incision is shorter than the one made in a full tummy tuck.
