Iron is indispensable to life. Human body the organism cannot synthesize without it hemoglobin necessary for oxygen transfer by bloody cells. Iron from the blasted erythrocytes is reused for formation of red bloody cells.
The non -pregnant woman loses with sweat, urine, feces, skin, fingernails and hair about 1-2 mg of iron every day, approximately the same quantity is soaked up in intestine. At menses 2-3 mg more iron daily are lost on average, at the plentiful menses – to 6 mg. Restoration requires sufficient supply of iron and normal work of all organs.
In the first three months of pregnancy the consumption of iron is equal to losses before pregnancy. But with growth of baby’s body the picture changes. In the second trimester (three months period) pregnant woman needs 2-4 mg of iron daily, in the third – 10-12 mg.
There can be extraordinary losses of iron at development of early toxicosis with vomiting, gastrointestinal tract disorder, change of hormonal background as a high level of estrogens reduces absorption of iron ions in the intestine. Chronic diseases also exhaust iron reserves and the absorption of iron is often broken and its consumption increases.
For restoration of iron reserves consumed for birth and feeding of the kid mother needs about 2-3 years.
Vitamin C stimulates iron absorption, but weakens calcium. It isn’t desirable to limit calcium consumption as the need for it is increased at pregnancy. A way out is a separate use of iron and calcium with an interval for 4 hours.
Vegetarians, pregnant women at teenage age if hemoglobin level by the beginning of pregnancy was less than 120 g/l, women with polycarpic pregnancy are included to group of risk.
