What does missed abortion mean?

Missed abortion is relatively common in clinical practice. It is when the embryo dies and has not been expelled naturally after 2 months. When there is long-term mental stress, chromosomal abnormalities, some diseases, and long-term exposure to chemicals, it is easy to cause missed abortion. At this time, it will cause symptoms such as cessation of menstruation, abdominal pain, and vaginal bleeding.

The harm caused by missed abortion is relatively large, which needs to be taken seriously and treated in time. Many people in life are definitely not clear about what missed abortion means. Let's take a closer look at it.
Missed abortion refers to a phenomenon in which the embryo has died but is still in the uterus. The products of pregnancy are usually expelled within 1-2 months after the onset of symptoms. If they are not expelled naturally after 2 months, it is called missed abortion.
There are mental reasons for missed abortion. If the mental stress is high and the patient is in a state of fear, anxiety, tension, and worry for a long time, it is easy to cause missed abortion. If the patient's chromosomes are abnormal, or the couple's blood types are incompatible, and one of the chromosomes is mutated. If the patient suffers from uterine tumors, cytomegalovirus infection, severe diabetes, hypothyroidism, and luteal insufficiency, it is also easy to cause missed abortion.
If you have a habit of smoking a lot, drinking alcohol for a long time, or taking drugs in your daily life, it is also easy to cause it. If you need to frequently come into contact with chemicals such as formaldehyde, lead, benzene, ethylene oxide, etc. due to work reasons. Or if you work in the imaging department and need to be frequently exposed to radiation, it is also easy to cause missed abortion.
Missed abortion will cause symptoms of cessation of menstruation, and there may be threatened abortion in the early stage, after which the uterus will gradually become smaller. In the middle stage, the abdomen will slowly become larger, but there will be no fetal movement. During the examination, it will be found that the uterus is relatively small and the fetal heart rate cannot be monitored.
Missed abortion also has abdominal pain symptoms. This abdominal pain is caused by blood clots irritating the uterus, causing uterine contractions. There will also be vaginal bleeding. If the abortion occurs within three months of pregnancy, there will be bleeding due to the separation of the villi and the membrane. The bleeding will be bright red at the beginning of the abortion, and then it will turn dark red and brown.
