Braxton Hicks: False vs. Real Labor

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Understanding the difference between Braxton Hicks contractions and true labor is crucial for expectant mothers. Braxton Hicks contractions, often referred to as “false labor,” can cause confusion and anxiety, especially for first-time mothers. This article aims to elucidate the distinctions between these two types of contractions, drawing on recent research findings.

What are Braxton Hicks Contractions?

Braxton Hicks contractions are irregular, often painless contractions that occur during the second trimester of pregnancy. These contractions are the body’s way of preparing for the eventual labor but do not indicate the onset of true labor. According to a study on pain track analysis during gestation, these contractions are typically unnoticed and do not follow a regular pattern1.

Characteristics of Braxton Hicks Contractions

• Irregular Timing: Unlike true labor contractions, Braxton Hicks contractions do not occur at regular intervals.
• Painless or Mild Discomfort: These contractions are usually painless or cause only mild discomfort.
• No Progression: They do not increase in intensity or frequency over time.
• Relief with Movement: Changing positions or walking often alleviates the discomfort caused by Braxton Hicks contractions.

What is True Labor?

True labor contractions signify the beginning of the labor process and occur late in the third trimester, usually beyond the 36th week of gestation. These contractions are regular, increase in intensity, and lead to cervical dilation and effacement, ultimately resulting in childbirth1.

Characteristics of True Labor Contractions

• Regular Intervals: True labor contractions occur at regular intervals and become closer together over time.
• Increasing Intensity: The pain and intensity of the contractions increase progressively.
• Cervical Changes: True labor leads to cervical dilation and effacement.
• Persistent Pain: Unlike Braxton Hicks contractions, true labor pain does not subside with movement or changes in position.

Differentiating Between Braxton Hicks and True Labor

Recent advancements in technology have provided new methods to differentiate between Braxton Hicks and true labor contractions. An external labor-onset monitor that processes the frequency spectrum of uterine electromyograms (EMG) has shown promise in distinguishing between the two. This monitor calculates a parameter (DELTA) that indicates true labor with positive values and Braxton Hicks with negative values. Preliminary findings suggest that patients with three consecutive positive DELTA values delivered within 36 hours, while those with negative values did not2.

The Importance of Accurate Identification

Accurate identification of true labor is essential to prevent unnecessary medical interventions and ensure timely care. Misinterpreting Braxton Hicks contractions as true labor can lead to undue stress and potential complications. Conversely, dismissing true labor as false contractions can delay necessary medical attention. Some researchers argue that the term “Braxton Hicks contractions” may lead to complacency and discourage patients from seeking prompt medical care, potentially overlooking early signs of preterm labor3.

Conclusion

Differentiating between Braxton Hicks and true labor contractions is vital for the well-being of both the mother and the baby. While Braxton Hicks contractions are a normal part of pregnancy, recognizing the signs of true labor ensures timely medical intervention and a safer delivery process. Advances in monitoring technology and a better understanding of contraction patterns can aid in this differentiation, providing expectant mothers with the necessary information to take appropriate action.
