Although a healthy diet and regular exercise routine can go a long way toward improving the look of your body, these healthy habits can’t always give you the firm, toned look you want — especially when excess skin is involved. For many people, pregnancy or a rapid, substantial weight loss (such as that which occurs after bariatric surgery) can leave behind a layer of sagging skin that’s impossible to reduce without surgery. During a tummy tuck, Dr. Olson removes this skin and often tightens loose or weakened abdominal muscles for a deep, balanced improvement.
