Brief Summary

Anemia is a common problem during pregnancy. Most studies have demonstrated that anemia during pregnancy have adverse effects on their pregnancy outcome, which is important and should pay attention to prevent and solve such problems. The most common cause of anemia is iron deficiency. Several studies reveal that Vitamin C promotes iron absorption. In this study we will compare between Vitamin C with iron supplement and iron supplement alone in prevention of anemia in pregnancy.

Detailed Description

Anemia in pregnancy associated with Diabetes during pregnancy 15.9 % Fetal abnormalities in blood oxygen causing fetal non reassuring 9.4% , Preterm delivery 8.2 %, Amniotic fluid insufficiency 1.95 %, 10.6 % of infants had complications after birth, 9.7 % of infants were hospitalized in intensive care units with birth weight less than 2,500 grams . (Low birth weight) 4.9%, anemia also significantly increased the likelihood of blood transfusion during pregnancy.

There is also a study on the risk of developing anemia such as more than 2 pregnancies, Teenage pregnancy, Advanced maternal age more than 35 years old, Mothers with a body mass index below 18 are at increased risk of developing anemia. The most common cause of anemia during pregnancy is iron deficiency. This may be caused by receiving the element. not enough iron or there is a loss of iron from blood loss which is important and should pay attention to prevent and solve such problems. Which Vitamin C promotes iron absorption. Vitamin C combined with iron has been studied. It clearly increases hemoglobin and hematocrit. And is safe for pregnant women and babies. There is also no evidence that vitamin C is a carcinogen, or a cause of birth defects or toxicity. However, there are no studies related to the combination of vitamin C and iron in pregnant women at risk of anemia. To solve the problem and prevent the consequences of the above mentioned anemia. In this study we will compare between Vitamin C with iron supplement and iron supplement alone in prevention of anemia in pregnancy.
