Is it possible to get more stretch marks after tummy tuck?

Thank you for your email. It would be unusual to develop new stretch marks following an abdominoplasty or tummy tuck, but stretch marks are due to undue tension in the skin that causes an actual fracture of the dermis. This is usually related to pregnancy or massive weight gain, but we also see this on occasion in breast augmentation in breasts that were tight. As a rule, most of the existing stretch marks that exist in the tummy skin that is below the belly button can often be eliminated, and it would be unusual to see new ones develop after that. More information can be derived during your consultation with a board certified plastic surgeon experienced in body contouring surgery.Best of luck to you in achieving the enhancement you are seeking. 

The purpose of a tummy tuck is actually to remove stretch marks and while your question makes total sense because the skin will be stretched, the simple answer is no.  Stretch marks occur because of expansion of the space beneath the skin such as with weight gain, pregnancy, sometimes breasts augmentation and even sometimes in weight lifters with rapid muscle expansion.  You should not develop more stretch marks from the tummy tuck unless you were to gain weight afterwards or become pregnant.  Best of luck should you decide to pursue a tummy tuck!
