Pregnancy and puerperium during lactation

As the lactation period extends, the chance that they still breastfeed when they get pregnant increases. The studies show that there is no increase in the risk of miscarriage, preterm labor and intrauterine growth retardation. On the other hand, when pregnant woman maintains lactation, it seems that birth weight to be born decreases. No guidelines has been found in the literature showing the daily calorie, protein, vitamin and mineral needs of lactating pregnant women; however, it should be taken into consideration that energy, protein, vitamin, mineral and water needs of pregnant women who also lactate increase. Although the data in the literature indicates that lactating during pregnancy is safe, available studies cannot prove that lactation during pregnancy is either harmful or useful for mother/fetus/baby.
