Anemia is a condition in which blood has a lower-than-normal amount of red blood cells or hemoglobin. [1] Anemia in pregnancy is a decrease in the total red blood cells (RBCs) or hemoglobin in the blood during pregnancy. Anemia is an extremely common condition in pregnancy world-wide, conferring a number of health risks to mother and child. [2]
For example, during pregnancy a woman's RBC mass is normal but because of an increase in blood volume the hemoglobin and hematocrit are diluted and thus decreased. Another example would be bleeding where the RBC mass would decrease but the concentrations of hemoglobin and hematocrit initially remains normal until fluids shift from other areas ...
Anemia prevalences during pregnancy differed from 18% in developed countries to 75% in South Asia; culminating to a global rate of 38% of pregnancies worldwide. [ 1 ] [ 5 ] [ 32 ] Treatment varies due to the severity of the anaemia, and can be used by increasing iron containing foods, oral iron tablets or by the use of parenteral iron .

Folate deficiency anemia during pregnancy may give rise to the birth of low weight birth premature infants and infants with neural tube defects. [6] Not consuming enough folate can lead to folate deficiency within a few months. [1] Otherwise, causes may include increased needs as with pregnancy, and in those with shortened red blood cell ...
During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell concentration.

Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
