How long will it take for early pregnancy bleeding to lead to spontaneous abortion?

Generally, there will be bleeding when the fertilized egg implants, which may last for 1-2 days. However, if the bleeding lasts for more than 3 days and the blood flow is large, there is a high probability of spontaneous abortion, so timely treatment is necessary in this case. In addition, you must pay attention to your diet and eat more easily digestible and easily absorbed foods.

1. How long will it take for early pregnancy bleeding to lead to spontaneous abortion?

Generally, it is difficult to preserve the fetus if bleeding lasts for more than 3 days. It is necessary to increase nutrition, supplement vitamins and trace elements, and eat food that is easy to digest and absorb.

2. Causes of Spontaneous Abortion

1. Incomplete embryonic development: Abnormal fertilized eggs are the main cause of early miscarriage. About 80% of miscarriages in the first two months of pregnancy are due to some defects in sperm and eggs, which cause the embryo to develop to a certain extent and then terminate. Therefore, the original embryonic tissue cannot be seen in the discharge of this type of miscarriage.

2. Endocrine dysfunction: The fertilized egg can only implant on the uterine wall and grow into a fetus under the action of progesterone. When the body does not secrete enough progesterone, the uterine decidua will develop poorly, thus affecting the development of the fertilized egg and easily causing miscarriage. If the amount of prostaglandins increases, it will cause frequent contractions of the uterine muscles and may also lead to miscarriage. Reduced thyroid function can cause cell oxidation disorders, thereby affecting the growth and development of the embryo and causing miscarriage.

3. Reproductive organ diseases: uterine malformations such as bicornuate uterus, septate uterus, and uterine hypoplasia. Pelvic tumors, especially submucosal fibroids, can affect the growth and development of the fetus and cause miscarriage. Relaxation of the internal os of the uterus or deep laceration of the cervix can cause premature rupture of membranes and late miscarriage.

4. Systemic diseases of pregnant women: When pregnant women suffer from acute infectious diseases such as influenza, typhoid fever, pneumonia, etc., bacterial toxins or viruses enter the fetus through the placenta, causing fetal poisoning and death. High fever can promote uterine contractions and cause miscarriage. Pregnant women suffering from chronic diseases such as severe anemia, heart failure, chronic nephritis and hypertension may suffer fetal disability and miscarriage due to placental infarction and intrauterine hypoxia. Malnutrition of pregnant women, especially vitamin deficiency, as well as mercury, lead and alcohol poisoning can cause miscarriage.

5. Trauma: The abdomen of a pregnant woman is hit or squeezed by external force, or she falls or participates in heavy physical labor or strenuous sports; abdominal surgery such as appendicitis or ovarian cyst surgery can cause uterine contraction and miscarriage.

6. Sudden changes in emotions: Pregnant women’s emotions are severely stimulated. Excessive sadness, shock, fear, and excessive emotional excitement can cause environmental imbalance in the pregnant woman’s body, prompting uterine contractions and causing miscarriage.
