What is the distinction between true and false labor?

True labor is defined by the occurrence of contractions that not only become progressively more frequent and intense but also lead to cervical changes, specifically dilation and effacement. This process is an integral part of labor and delivery, indicating that the body is preparing for childbirth.

In true labor, contractions typically grow stronger and more regular over time, causing the cervix to begin to open and thin out, a critical process for delivering the baby. This physical change is what ultimately signifies true labor as it demonstrates that the body is actively engaging in the labor process.

In contrast, false labor, often referred to as Braxton Hicks contractions, is characterized by irregular contractions that do not effect change in the cervix. These contractions can occur at any point during pregnancy, but they do not indicate that labor is imminent. Thus, the distinction lies in the presence of cervical dilation during true labor, which is not observed in false labor.
