A molar pregnancy is a genetic abnormality that develops into an embryo, characterized by proliferation of nourishing cells, interstitial edema, and a grape like appearance during pregnancy. It is an abnormal pregnancy that can cause a series of clinical symptoms such as irregular vaginal bleeding and lower abdominal pain after menopause. Thyroid crisis or gestational hypertension may occur. So, why does it form a molar pregnancy?
There are many factors that can lead to the formation of molar pregnancy, such as infection, nutrition, racial factors, endocrine disorders, etc.
1. Nutritional factors: hydatidiform mole mostly occurs in areas where rice is the staple food. In addition, the lack of vitamin A intake will increase the incidence rate of hydatidiform mole. For example, low consumption of carotene in diet will increase the incidence rate of hydatidiform mole.
2. Infection factors. Many people believe that viral infection can lead to molar pregnancy, but there is currently no evidence to support this conclusion.
3. Endocrine disorders. Ovarian dysfunction or insufficiency can also lead to molar pregnancy, which mostly occurs in women under the age of 20 or over the age of 40.
4. Defects in pregnant eggs may be related to abnormal development of the eggs themselves.
5. Racial factors and the differences in the incidence rate of hydatidiform mole among ethnic groups have attracted people's attention. For example, the probability of African Americans suffering from molar pregnancy is only half of that of others. The incidence of hydatidiform mole in Singapore, Asia, Europe and other countries is twice as high as that in China, India and other countries.
