Why do you get hydatidiform mole?

Why does hydatidiform mole occur?

Molar pregnancy makes pregnant women very scared, because molar pregnancy can easily cause miscarriage and endanger health. There are many reasons for molar pregnancy, such as inadequate nutritional supplements or viral infection. If a female friend has endocrine disorders or defective fertilized eggs, it can also cause molar pregnancy. Racial factors can also cause molar pregnancy, so prevention work should be done well.

1. Nutritional factors

Mole often occurs in areas where rice is eaten, so many people believe that it is related to nutrition. Studies have found that patients with gestational trophoblastic tumor (GTT) have low serum folate activity. Folate deficiency during the embryonic angiogenesis period affects the synthesis of thymine, which in turn leads to embryonic death and lack of placental villous blood vessels. Low dietary carotene consumption increases the risk of mole. The incidence of mole increases in areas with vitamin A deficiency. The content of trace elements Zn and Se in mole tissue decreases.

2. Infectious factors

Many people believe that hydatidiform mole is related to viral infection, but no relevant evidence has been found so far.

3. Endocrine disorders

Some scholars also believe that the occurrence of hydatidiform mole is related to imperfect or declining ovarian function, and therefore mainly occurs in women under 20 and over 40. Animal experiments have shown that if the ovaries are removed in early pregnancy, the placenta will undergo vesicular changes, so estrogen deficiency may also be the cause of hydatidiform mole.

4. Defective fertilized egg

It may be related to abnormal development of the egg itself.

5. Racial factors

The incidence of hydatidiform mole varies between different ethnic groups. It is reported that the incidence of hydatidiform mole in black women in the United States is only half that of other women. In Singapore, the incidence of hydatidiform mole in Eurasian people is twice that of Chinese, Indians and Malaysians.
