In plain words
Braxton Hicks is the older name for the irregular tightening of the uterus that many pregnant people feel in the later months. It is named after John Braxton Hicks, an English obstetrician who described these contractions in 1872. The belly becomes firm for a short time and then softens. The tightening is usually irregular and does not get closer together or stronger over time. Many mothers are surprised by them the first time. Clinicians use the name Braxton Hicks and the longer phrase for the same experience. Their presence on its own does not mean labor has started, which is why the difference from true labor matters.
The deeper version
Braxton Hicks contractions, named for the English obstetrician John Braxton Hicks, who described them in 1872, are irregular uterine contractions that begin in the second trimester and are felt more often in late pregnancy. Uterine recordings show activity of lower intensity than true labor contractions, without the progressive frequency, duration, and cervical change that mark labor. Their proposed functions, such as uterine conditioning, are not established. Some clinicians note that they can feel stronger with dehydration or a full bladder, though the evidence is largely observational. The clinically relevant task is distinguishing them from , which is recognized by regular, increasing contractions, cervical change, and symptoms such as pelvic pressure or bleeding.
