Early pregnancy: From the sixth week of pregnancy, the increase of plasma in pregnant women's blood is more than that of red blood cells, which leads to the dilution of blood and is prone to "physiological anemia". At this stage, it is necessary to supplement15mg of iron every day. It is recommended to supplement iron through diet, and eat more animal foods such as fish, lean meat, liver, eggs, dried shrimps and fresh vegetables.
Second trimester: During the period from 13 to 28 weeks, pregnant women need to supplement 25 mg of iron every day. It is recommended that expectant mothers eat more foods rich in heme and iron such as meat and liver, and supplement vitamin C to increase iron absorption.
Third trimester: In the 29th to 40th week, pregnant women need to take 35 mg of iron every day. Because pregnant women need to prepare iron for blood loss and lactation during this period, the fetal liver will also store iron at a rate of 5mg per day until it reaches 300-400mg at birth. It is suggested that expectant mothers should take iron supplements under the guidance of doctors in addition to eating more iron-rich foods.
Note: Because each pregnant woman's physique is different, the amount of iron supplement is also different, but most pregnant women come according to this standard. Because some pregnant women have poor absorption or lack more, they need to increase the supplement appropriately. Relatively, pregnant women with good absorption or no iron deficiency can reduce it appropriately. Therefore, pregnant women had better go to the hospital for examination and consult their doctors about the amount of iron supplement.
When do pregnant women supplement iron? After pregnancy, pregnant women's daily demand for iron will increase, and most of them exceed the amount of iron stored in pregnant women's bodies. Therefore, pregnant women should be able to supplement iron from the beginning of pregnancy, and the best time is the second month of pregnancy, but in the early pregnancy, pregnant women don't need much iron. It is best to choose the way of food supplement and eat more iron-rich foods, such as lean meat, poultry, animal liver and blood (duck blood, pig blood).
Iron supplementation in the second and third trimester of pregnancy depends on the iron deficiency of pregnant women themselves. Generally, when pregnant, doctors will tell you if iron supplementation is needed. At this time, iron supplementation is generally recommended, but iron supplementation should not be eaten for too long. Generally, you should go to the hospital to check the iron supplement after taking it for about half a month, and you should stop using it when it reaches the normal level.
Precautions for iron supplementation in pregnant women 1, pay attention to vitamin C intake.
Vitamin C can promote the absorption of iron, and should be taken within four hours after meals. Be careful not to drink tea and coffee when supplementing iron, because the polyphenols contained in tea and coffee will interfere with your body's absorption of iron in iron supplements and iron-containing plants, thus affecting your iron supplement effect.
2, iron supplementation should be early.
Iron supplementation is a long-term process, and it is not easy to absorb iron due to serious pregnancy reaction in early pregnancy. It is best to consciously supplement iron in the first half year of pre-pregnancy preparation.
