Causes of complete hydatidiform mole

Complete hydatidiform mole is actually more harmful than partial hydatidiform mole because it may cause other lesions. The causes of complete hydatidiform mole are also related to one's own eating habits, so you may want to learn about it.

Complete hydatidiform mole: All the placental villi are affected, there is no fetus and its appendages, and the uterine cavity is filled with blisters; even if only one sperm enters the egg, problems may occur. If the mother's egg is an "empty egg", it will cause chromosomal abnormalities because only the father's chromosomes are constantly dividing, which will cause the trophoblast to continue to proliferate, but there is no fetus. The same thing will happen if two sperm enter an empty egg at the same time. This condition is called a complete molar pregnancy.

Complete hydatidiform mole may be related to factors such as region, race, nutrition, socioeconomic factors and gestational age.

(1) People whose diets lack vitamin A, its precursor carotene, and animal fat are at a significantly increased risk of developing hydatidiform mole.

(2) Age is another high-risk factor. The incidence of hydatidiform mole in women aged 35 and 40 is 2 times and 7.5 times that of younger women, respectively. Conversely, the incidence of hydatidiform mole in women younger than 20 years old is also significantly increased.

(3) A history of hydatidiform mole in a previous pregnancy is also a high-risk factor. The incidence of subsequent hydatidiform mole in women with a history of one or two hydatidiform mole pregnancies is 1% and 15% to 20%, respectively.
