What are the reasons for miscarriage of her fetus?

 Abortion is medically expressed as miscarriage, and occurs when the fetus dies before reaching the twentieth week of pregnancy; That is, in its early stages, and it is considered one of the difficult experiences to overcome emotionally, and it causes the mother to feel sadness and loss despite it being a common medical condition that many mothers go through. BMC Pregnancy and Childbirth magazine published a statistic in 2017 that included a large number of women. In it, the percentage of women who underwent an abortion during the first trimester of pregnancy may reach 43% of them.


Causes of a miscarriage:

As the main cause of miscarriage is often not recognized despite the presence of many reasons behind it, and it can be said that abortion during the first trimester of pregnancy is often due to the presence of problems in the fetus itself, but if it occurs after the first three months; Because this may be related to the mother’s suffering from a specific health problem, the causes of miscarriage will be explained in some detail:


Chemical pregnancy:

Where a chemical pregnancy or the so-called biochemical pregnancy leads to miscarriage in the early stage of pregnancy, specifically after the embryo implants in the uterus; As the gestational age does not exceed five weeks in this case, the result of the pregnancy test may be positive without the mother showing symptoms of pregnancy; Such as the absence of a menstrual period, except that the symptoms associated with a miscarriage in the early stages of pregnancy are not severe, and it is possible to confuse them with the symptoms of a normal menstrual cycle, such as; Abdominal pain or uterine bleeding, and thus a woman may be unaware of the existence of a pregnancy if she does not perform a pregnancy examination, taking into account that the imaging does not show the fetus when imaging is performed at these stages of pregnancy, and therefore it can be said that it is possible for a woman to undergo a chemical pregnancy experience and abort it without her knowledge So .



Placenta problems:

Where the placenta is defined as a large organ that develops during pregnancy, and is often connected to the top or side of the uterine wall, and the umbilical cord connects the fetus to the placenta, and the role of the placenta is to transfer blood from the mother to the child to provide him with his need of oxygen, glucose, and other nutrients. Very important for the development and growth of the fetus, which means that problems with the placenta may sometimes lead to a miscarriage, and among these problems:

  •  Toxic transfer: the mother may sometimes transfer some toxic substances to the fetus or to the pregnancy tissues, which leads to problems in the placenta, and these substances include alcohol, excess caffeine, some environmental substances, and drugs that are not authorized for use during pregnancy, and drugs.

  • Harmful cell transfer: The mother sometimes transfers some harmful cells to the tissues of the pregnancy or the fetus. These cells are caused by infection or uncontrolled chronic health conditions.

  • Placental insufficiency: where the abnormal growth of the placenta leads to the stopping of the blood supply to the child, which affects his growth and development, if this condition prevents the fetus from providing sufficient quantities of hormones, antibodies, oxygen, and nutrients, and it is worth noting that placental insufficiency It especially happens if the placenta does not grow enough to support and maintain the fetus, and this may sometimes happen when a woman is carrying twins of fetuses instead of one.



Cervical insufficiency:

Cervical insufficiency may lead to miscarriage during the second trimester of pregnancy due to the inability of the cervix to maintain pregnancy, and some symptoms may often appear before the occurrence of the miscarriage in this case, such as a feeling of sudden pressure, the descent of the fetal water, and the exit of some fetal tissue or the placenta without It is painful.


Uterine problems:

The risk of miscarriage during the second trimester increases if there are problems with the uterus, such as; The irregular shape of the uterus so that it contains a limited space in addition to the presence of a growth in it called uterine fibroids, among these problems:

  • The bicornuate uterus: In this case, the uterus can be likened to the shape of the heart, and its presence increases the risk of miscarriage and premature labor, but it does not cause any difficulties for the woman towards achieving pregnancy or any problems in the early stages of pregnancy.

  • Unicorn uterus: the size of the uterus in this case does not exceed half the normal size, and it is considered one of the rare cases, which occurs as a result of failure to grow one side of the uterus, and its presence leads to an increased risk of ectopic pregnancy, miscarriage in the late stages of pregnancy, and premature labor.

  •  The reserved uterus: The uterus in this case is described by the presence of a muscular wall that starts at the center of the uterus and divides it into two parts, so that this wall separates the uterus completely or partially, and this results in an increased risk of suffering from several problems, such as difficulty in pregnancy, and miscarriage in the first trimester of pregnancy And early labor.

  •  An arched uterus: It resembles a normal uterus to some extent with a bow or slope at its top, and sometimes leads to an increased risk of miscarriage in the second trimester of pregnancy, without increasing the risk of miscarriage in the first trimester or premature labor.
