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.

Anemia is a globally recognized complication of pregnancy worldwide and is a condition with a low hemoglobin amount in one of the trimesters. Such physiological modifications are more pronounced among individuals who suffer from undernutrition as well as chronic diseases associated with hemoglobin rehoming, like sickle cell anemia.
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
Screening for diabetes during pregnancy continues to require fasting and glucose-tolerance measurements for gestational diabetes at 24 to 28 weeks gestation, although glycated hemoglobin may be used for screening at the first prenatal visit. [37]
Hemoglobin has an oxygen binding capacity between 1.36 and 1.40 ml O 2 per gram hemoglobin, [23] which increases the total blood oxygen capacity seventyfold, [24] compared to if oxygen solely were carried by its solubility of 0.03 ml O 2 per liter blood per mm Hg partial pressure of oxygen (about 100 mm Hg in arteries).
Amniotic fluid index (AFI) is a quantitative estimate of amniotic fluid [1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [1]
In women, being severely underweight, often as a result of an eating disorder or due to excessive strenuous exercise, can result in amenorrhea (absence of menstruation), [20] infertility or complications during pregnancy if gestational weight gain is too low. [citation needed] Malnourishment can also cause anemia and hair loss.
