What is the reason for lower abdominal prolapse after medical abortion?

Regarding the issue of unexpected pregnancy, if women do not want to go to the hospital for surgery, they can use medical drainage to remove the baby. However, there are still certain risks when using medical abortion, because if the fluid in the uterus cannot be completely excreted, inflammation is likely to occur. Some people will feel a falling sensation in their lower abdomen after medical abortion, so you must go to the hospital for diagnosis in time.

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.

Binary classification

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.

Three clinical manifestations

First-time mothers will feel fetal movement at around 20 to 24 weeks of pregnancy, while multiparas will feel it earlier, around 16 weeks. When the fetus moves, in addition to the mother's feeling of the fetus rolling in the uterus, the fetus's back or hands and feet may also push against the uterine wall due to the movement, causing part of the uterus to harden or deform. This is a normal phenomenon.

In addition, in the weeks before delivery, the uterus will have spontaneous uterine contractions called Broaxtons. Hick's contractions may occur several times a day. This is a normal false pain and is not a big deal. Just get more rest.

However, before full term, if the uterus has a regular feeling of tightness every hour, such as once every 10 or 15 minutes, and if it does not improve after bed rest, then this is abnormal uterine contraction. If it has not reached 37 weeks, premature birth is very likely to occur, and you need to rest in bed and go to the hospital immediately for appropriate treatment.

Four treatments

When threatened premature labor occurs, the first thing to do is to inhibit uterine contractions. Commonly used drugs include hydroxybenzylhydroxyephedrine, etc., and the safety of the fetus should be assessed while taking the drugs.
