The term "TOLAC" stands for Trial of Labor After Cesarean. In medical contexts, it refers to the process in which a woman who has previously undergone a Cesarean delivery attempts a vaginal delivery for her subsequent pregnancy. There are several synonyms that are used to describe TOLAC, such as vaginal birth after Cesarean (VBAC), labor after Cesarean (LAC), and natural birth after Cesarean (NBAC). These terms are often used interchangeably in the medical community to describe the same process. Ultimately, the goal of TOLAC is to provide women with the opportunity to have a successful vaginal delivery following a Cesarean section.
