There are 3 reasons why pregnant women have low vitamin B12 levels:
1, the lack of supply of vitamin B12 in food, occurs in the long-term habits of people eating vegetarian.
2, the lack of "intrinsic factor", this intrinsic factor is a glycoprotein secreted by the gastric cardia and gastric mucosa, which can be caused by congenital deficiency or total gastrectomy.
3, some infectious diseases can affect the intestinal absorption of vitamin B12.
If pregnant women have low levels of vitamin B12, they often experience dyspnea, which usually occurs after walking but is not accompanied by chest pain. Once pregnant women find that their vitamin B12 is relatively low, it is recommended to obtain vitamin B12 through animal liver and other foods.
