What distinguishes preterm labor from false labor?

The distinction between preterm labor and false labor primarily hinges on the timing of contractions, their regularity, and the physiological changes in the cervix. Preterm labor is defined as labor that occurs before 37 weeks of gestation and is characterized by regular contractions that lead to changes in the cervix, such as effacement and dilation. These contractions are often consistent in frequency and intensity, marking a genuine progression toward childbirth.

In contrast, false labor does not significantly affect the cervix, and the contractions observed are typically irregular and do not lead to cervical changes. False labor may resemble real labor in terms of discomfort, but it does not produce the physiological results associated with true labor. Recognizing these differences is crucial for assessing a patient’s condition appropriately, determining the need for intervention, and planning for delivery. Thus, understanding that preterm labor is associated with regular contractions and cervical changes before 37 weeks is essential for accurate clinical assessment.
