Ventral hernias can develop over a long period of time, either as a congenital defect at birth, during or after pregnancy, or as the abdominal muscles gradually weaken due to years of absorbing stress. They can also form months or years after an abdominal surgery.

Ventral hernias cannot heal on their own.
