Braxton Hicks Contractions: Causes and Treatment
You might have heard this funny phrase before you were pregnant, but now you want to know what it means. The term originated in 1872 when an English doctor named John Braxton Hicks described the contractions that occur before real labor.
Imagine constantly thinking, “This must be it,” only to find out that it wasn’t. Doctors and pregnant women have Dr. Hicks to thank for eliminating the confusion. The following information should be helpful in determining the difference between true labor and Braxton Hicks contractions.
What are Braxton Hicks contractions?
Braxton Hicks contractions can begin as early as the second trimester. However, they are most commonly experienced in the third trimester. When this happens, the muscles of the uterus tighten for approximately 30 to 60 seconds, and sometimes as long as two minutes.
Braxton Hicks are also called “practice contractions” because they are a preparation for the real event and allow the opportunity to practice the breathing exercises taught in childbirth classes.
Braxton Hicks are described as:
- Irregular in intensity
- More uncomfortable than painful (although for some women Braxton Hicks can feel painful)
- They do not increase in intensity or frequency
- They taper off and then disappear altogether
If your contractions are easing up in any way, they are most likely Braxton Hicks.
What causes them?
There are possible causes of these contractions. Some physicians and midwives believe that they play a part in toning the uterine muscle and promoting the flow of blood to the placenta. They are not thought to have a role in dilating the cervix but might have some impact on the softening of the cervix.
What triggers them?
The following are triggers of Braxton Hicks:
- When the mother or the baby is very active
- If someone touches the mother’s belly
- When the bladder is full
- After sex
What can I do to alleviate Braxton Hicks contractions?
- Change positions. You can lie down if you have been standing or go for a walk if you have been sitting or laying
- Take a warm bath for 30 minutes or less
- Because contractions may be brought on by dehydration, drink a couple of glasses of water
- Drink a warm cup of herbal tea or milk
If none of these steps work, you should contact your health care provider.
