A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:
Pregnant women need almost twice as much iron as women who are not pregnant do. Not getting enough iron during pregnancy raises risk of premature birth or a low-birth-weight baby. [ 23 ] Hormonal changes in the pregnant woman result in an increase in circulating blood volume to 100 mL/kg with a total blood volume of approximately 6000–7000 mL.
Anemia (also spelled anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]
[2] [3] However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency. [citation needed] Anemia is the most common disorder of the blood. There are several kinds of anemia, produced by a variety of underlying causes.
an uncompensated increase in plasma volume (e.g., pregnancy, fluid overload); a B2 deficiency [3] a B6 deficiency [3] or a mixture of conditions producing microcytic and macrocytic anemia. [1] Blood loss, suppressed production of RBCs or hemolysis represent most cases of normocytic anemia.

Pregnant women fall at a similar rate (27%) to women over age of 70 years (28%). Most of the falls (64%) occur during the second trimester. Additionally, two-thirds of falls are associated with walking on slippery floors, rushing, or carrying an object. [38] The root causes for these falls are not well known.
