Although women who have undergone tummy tuck surgery are still physically capable of becoming pregnant, Dr. Calobrace typically advises against it. This is because the changes a woman's body undergoes during pregnancy can negatively affect her tummy tuck results, potentially necessitating revisionary surgery at a later date. If you're considering a tummy tuck but aren't sure whether you'd like to have more children, it may be best to wait until you're done growing your family.
