Causes of abdominal cramps in pregnant women

The family is very concerned about every tiny change in the pregnant woman's belly, because if there is a problem with the pregnant woman's belly, it will not only affect the physical health of the pregnant woman but also the development of the fetus. Therefore, we recommend that pregnant women must pay attention to their belly in daily life. Once there is a problem with the belly, they should go to the hospital for consultation in time. Below we introduce the reasons for abdominal cramps in pregnant women.

The uterus nurtures the fetus. As the fetus grows and the placenta produces hormones, the uterus becomes significantly larger and softer. The capacity of the uterine cavity increases 1,000 times, and the weight of the uterus increases 20 times. The main histological changes are hypertrophy of uterine muscle cells, with the cytoplasm filled with contractile actin and myosin, which provide the material conditions for uterine contraction after delivery. The isthmus of the uterus is located inside the cervical canal and is about 0.8 to 1.0 cm long when not pregnant. After pregnancy, as the uterus grows larger, the isthmus gradually stretches, becomes longer and thinner, and expands to become a part of the uterine cavity, forming the lower segment of the uterus, which can stretch to 7 to 10 cm during labor. The uterus often contracts during pregnancy, which can be divided into physiological and pathological types.

1. Physiological

Physiological uterine contractions can occur from 12 to 14 weeks of pregnancy, manifesting as irregular painless contractions. Pregnant women can feel the tightening of the abdomen and the hardening of the uterus from the abdomen. The number of contractions per day is sparse. Later, as the pregnancy progresses, the frequency and intensity of uterine contractions increase, but there is no regularity, and the intensity will not cause the intrauterine pressure to exceed 2KPa, so there is no pain of labor contractions. Under the action of physiological uterine contractions, the lower segment of the uterus is gradually formed, the cervix tends to soften and mature, and gradually transitions to uterine contractions after delivery.

2. Pathological

Pathological uterine contractions are seen in miscarriage or premature birth. Pathological uterine contractions during pregnancy are relatively strong and can cause the intrauterine pressure to exceed 2KPa, so they are all painful contractions. Miscarriage is often accompanied by uterine bleeding, while premature birth is characterized by the regularity and effectiveness of uterine contractions. If not treated in time, the cervix will shorten, the cervix will dilate, and there will be bloody vaginal discharge, and the threatened premature birth will develop into inevitable premature birth.

In the above article, we introduced a symptom that pregnant women are prone to, that is, abdominal cramps and pain.
