Symptoms of spontaneous abortion bleeding

We all know that for some women with gynecological diseases, the fetus may be more fragile during pregnancy, and it is easy to have an accidental miscarriage. Even if they do nothing and lie quietly in bed, they may still have a miscarriage. This phenomenon is called spontaneous abortion by doctors. So what are the clinical manifestations of spontaneous abortion and heavy bleeding? The following editor will introduce

1. What is spontaneous abortion?

Termination of pregnancy before 28 weeks of gestation and when the fetal weight is less than 1000g is called abortion. Among them, spontaneous abortion refers to abortion caused by non-human purposes. It is a miscarriage caused by natural factors. 31% of spontaneous abortions occur after embryo implantation, of which more than 80% are early abortions.

According to the different stages of miscarriage development, it can be divided into threatened abortion, inevitable abortion, incomplete abortion and complete abortion. There are also three special situations: missed abortion, habitual abortion, and abortion complicated by infection. Termination before 12 weeks of pregnancy is called early abortion, and termination between 12 weeks and less than 28 weeks of pregnancy is called late abortion. Abortion can be divided into spontaneous abortion and induced abortion, among which spontaneous abortion is mostly early abortion.

The main symptoms of spontaneous abortion are: vaginal bleeding and abdominal pain after menopause. The natural abortion goes through the following process: detachment of chorion and decidua - opening of blood sinuses - vaginal bleeding - vitreous embryo and blood stimulate uterine contraction - expulsion of embryo - lower abdominal pain.

1. Amenorrhea: Most pregnant women who have spontaneous abortions have a clear history of amenorrhea. Pregnancy can be confirmed by combining early pregnancy reactions, enlarged uterus, and the presence of an embryonic sac during B-type ultrasound examination. However, vaginal bleeding caused by early pregnancy miscarriage is difficult to distinguish from menstrual abnormalities, and there is often no obvious history of amenorrhea.

2. Vaginal bleeding and abdominal pain: Early miscarriage often begins with vaginal bleeding and then abdominal pain. Due to the death of the embryo or fetus, the chorion and decidua are separated, the blood sinuses open, and vaginal bleeding occurs; the separated embryo or fetus and blood stimulate the uterus to contract, expel the embryo or fetus, and produce paroxysmal lower abdominal pain; when the embryo or fetus is completely expelled, the uterus contracts, the blood sinuses close, and the bleeding stops.

The symptoms of late spontaneous abortion are similar to those of premature birth and full-term birth. After the placenta and fetus are delivered, there is generally not much bleeding. Abdominal cramps appear first, followed by vaginal bleeding.
