What is threatened abortion bleeding?

If a pregnant woman experiences threatened miscarriage, there will be a small amount of vaginal bleeding and other symptoms. In fact, there are often many reasons for this disease. It may be caused by the pregnant woman suffering from a systemic disease, or there may be a blood type incompatibility between the pregnant woman and the fetus in her womb. The most common reason is severe endocrine disorder.

Some pregnant women will find that they have obvious bleeding in the early stages of pregnancy. They will feel worried at this time, thinking that it will affect the health of the fetus. In fact, after some understanding, they will know that this may be caused by threatened abortion bleeding. However, most people may not understand it very well. So what is threatened abortion bleeding?
1. Pathology <br/>Women will experience a small amount of vaginal bleeding after pregnancy, sometimes accompanied by lower abdominal pain and a feeling of falling. This is a sign of threatened abortion. There are actually many different reasons for this phenomenon. First of all, you need to take preventive measures in your life, otherwise it may cause adverse consequences.
2. Causes
1. Systemic diseases <br/>If a pregnant woman suffers from systemic diseases, such as acute and serious infectious diseases, or some chronic diseases, as well as obvious vitamin deficiencies, miscarriage may occur.
2. Incompatibility of blood types <br/>In fact, if the blood types of the mother and fetus are incompatible, obvious antibodies will also appear. For example, blood types A, B, and O will also have a certain impact. Hemolysis may occur in this process, and threatened abortion bleeding may eventually occur.
3. Endocrine disorders <br/>Excessive estrogen and insufficient progesterone are both endocrine disorders and the cause of early miscarriage. Because during the 12th to 14th week of pregnancy, the embryo is in the process of formation, which is prone to endocrine disorders. In addition, there may be a lack of thyroid hormone, which seriously affects the oxidation process of cells and increases the chance of hyperthyroidism. All of these can lead to miscarriage.
4. Chromosomal abnormalities <br/>Chromosome studies of spontaneously aborted fetuses have revealed that 60% of them may have abnormalities. Those with karyotype abnormalities are often accompanied by structural abnormalities in the fetus or placenta.
5. Abnormal emotions <br/>If a pregnant woman is in a state of mental stimulation for a long time, such as excessive tension and fear, and these emotions are not effectively resolved for a long period of time, they may cause miscarriage and even threatened abortion bleeding.
