Braxton Hicks contractions

From WikiMD's Wellness Encyclopedia

Braxton Hicks contractions, named after the English doctor John Braxton Hicks who first described them in 1872, are sporadic uterine contractions that occur in pregnancy, often starting in the second trimester and becoming more frequent as the pregnancy progresses. These contractions, unlike true labor contractions, do not signal the onset of childbirth and are sometimes referred to as "practice contractions" or "false labor".

Characteristics[edit | edit source]

Braxton Hicks contractions are generally weaker than labor contractions, and their strength and frequency can vary. They are typically irregular, non-rhythmical, and do not increase in intensity over time. They often last for less than a minute and usually stop with movement or changes in position.

Function and Significance[edit | edit source]

The exact purpose of Braxton Hicks contractions is not fully understood. Some experts believe that these contractions help tone the uterine muscle in preparation for labor and promote the flow of blood to the placenta. They may also play a role in the effacement and dilation of the cervix.

It's important to differentiate Braxton Hicks contractions from true labor contractions. True labor contractions occur at regular intervals, increase in intensity and duration over time, and are usually accompanied by other signs of labor such as the breaking of the amniotic sac (water breaking) and cervical dilation.

Management[edit | edit source]

Generally, no medical treatment is required for Braxton Hicks contractions. They are a normal part of pregnancy and are not associated with any adverse outcomes. However, if the contractions become painful, regular, or are associated with any other signs of labor, medical advice should be sought as this could indicate the onset of premature labor.
