What is the cause of hydatidiform mole pregnancy?

Molar pregnancy is usually caused by malnutrition, poor living environment, previous history of molar pregnancy, chromosomal abnormalities, ovarian dysfunction, etc., as follows:

1. Malnutrition

If the patient has a picky diet for a long time, it is easy to cause vitamin A deficiency and animal fat deficiency in the body, which can lead to abnormal proliferation of placental villous trophoblasts, thereby inducing hydatidiform mole.

2. Poor living environment

Long-term exposure to polluted environments or frequent exposure to radioactive radiation can also lead to abnormal proliferation of placental villous trophoblasts and hydatidiform mole.

3. History of hydatidiform mole

If the patient has a history of hydatidiform mole, the probability of conceiving a hydatidiform mole is relatively higher than that of a person without a history of hydatidiform mole, and it is easy to become pregnant with a hydatidiform mole again.

4. Chromosomal abnormalities

If the man, woman or either party has chromosomal abnormalities, it will cause chromosome deletion and addition in sperm and egg, resulting in chromosomal abnormalities in the fertilized egg, leading to abnormal pregnancy and hydatidiform mole.

5. Ovarian dysfunction

If the patient is too young, the ovarian function is not perfect, and the normal pregnancy cannot be achieved, so he may be pregnant with a hydatidiform mole. If the patient is too old, the ovarian function declines, and the normal pregnancy cannot be achieved, so it is easy to be pregnant with a hydatidiform mole.

Molar pregnancy may also be related to other reasons such as regional factors and oral contraceptives.

The overall prognosis of hydatidiform mole is good. Most patients can achieve recovery after curettage. Normal childbirth is generally possible in the later stages, so there is no need to worry too much.
