Will the cervix shrink if it opens?

Although natural childbirth will cause great pain to women's bodies, considering the health of the baby and their own physical recovery, many women will still resolutely choose natural childbirth. Before choosing a natural birth, uterine contractions are an extremely important basis for judging the birth of the fetus. Because when uterine contractions occur frequently, they promote the dilation of the birth canal and the opening of the cervix. But if the cervix opens, will it open back up through contractions?

This is certainly possible. If it is almost time for your due date, you can consider walking more and climbing stairs. These can stimulate the contraction of the uterus and speed up the opening of the cervix.

Is there a relationship between uterine contractions and cervical dilation?

Uterine contraction is an important feature of labor. In short, it is the regular contraction of the uterus. The contractions are irregular and weak at first, then gradually become regular, becoming increasingly stronger, lasting longer, and with shorter intervals, such as an interval of 2-3 minutes, lasting 50-60 seconds. The last few months of pregnancy are characterized by irregular uterine contractions, especially in the last few weeks. After the fetal movement, just put your hands on your abdomen and you will feel your abdomen hardening from time to time. This type of contraction is irregular, non-cyclical, and painless.

In addition to physiological spontaneous uterine contractions, some external forces can also trigger uterine contractions.

1. Falling - When the abdomen is accidentally hit, it will not only compress the fetus in the uterus, but also reduce the blood supply in the uterus due to pain and shock. Severe impacts may even cause early placental detachment, endangering the lives of the mother and fetus.

2. Lifting heavy objects - When lifting heavy objects or moving items, you will exert force on the waist and lower abdomen, causing abdominal compression and uterine congestion, so there is a risk of miscarriage or premature birth. If you have to (such as holding a child), it is best to squat down and bend over first, hold the child or object tightly, and then stand up and raise your waist.

3. Common causes: uterine infection or extrauterine infection, such as urinary tract infection and vaginitis. Abnormal placenta, abnormal uterus or an enlarged uterus, such as multiple pregnancy or hydatidiform mole.

4. Tension and excessive fatigue - Clinical observation shows that pregnant women who are under excessive tension and fatigue for a long time are more likely to experience frequent uterine contractions.

5. Bending the body or taking a posture that compresses the abdomen - During pregnancy, the center of gravity leans forward, so many expectant mothers will unconsciously bend over and hunch back, but this posture can easily cause pelvic collapse, and the fetus cannot be maintained in the correct position. In addition, bending over will increase the burden on the body and cause pain in the back and lumbar spine.
