In the second trimester, if the pregnant woman has severe anemia, it affects the fetus’ insufficient blood supply, resulting in insufficient placental supply, which cannot supply the fetus’ nutrition well and affects the fetus’ organ development, and even seriously leads to fetal arrest and fetal death. If the symptoms of anemia appear in the second trimester, you should take timely supplements and eat more animal liver, milk, lean meat, egg yolk and other nutrient-rich foods to enhance nutrition. You can also eat more fruits and vegetables during this period because they contain a lot of vitamin C, which can promote the absorption of iron and improve the symptoms of iron deficiency anemia. You can also eat more black foods, such as shiitake mushrooms, fungus, kelp, which are good for supplementing and improving anemia.
