What are Braxton Hicks contractions?

Braxton Hicks contractions are characterized as irregular, painless contractions that occur during pregnancy, typically beginning in the second trimester. These contractions serve an important role in preparing the uterus for the process of labor. While they may be felt as a tightening of the abdominal muscles, they do not indicate that labor is imminent and are not associated with cervical dilation or effacement.

These contractions can help facilitate blood flow to the placenta and aid in conditioning the uterine muscle. Unlike regular contractions that signify active labor, Braxton Hicks contractions are often sporadic and do not follow a predictable pattern. Understanding this concept is crucial for expectant mothers, as it helps them differentiate between the normal sensations of pregnancy and the signs of true labor.
