During pregnancy, anatomical and physiological changes occur to meet the increased metabolic needs, to permit appropriate development of foetus and to prepare the body for childbirth.

Endocrine System Changes [edit | edit source]. The latent phase is commonly defined as the 0 to 6 cm, while the active phase commences from 6 cm to full cervical dilation. The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period.These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding.Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop.

In pregnant woman there are many physiological changes during pregnancy, which are entirely normal, including changes in different trimesters and changes in different systems like cardiovascular, metabolic, renal, hematologic, and respiratory changes. Maternal blood volume increases during pregnancy, and this involves an increase in plasma volume as well as in red cell and white cell volumes.1 The plasma volume increases by 40-50%, whereas the red cell volume increases by only 15-20%, which causes a "physiological anemia of pregnancy" (normal hemoglobin 12 g/dL; hematocrit 35).2 Because of this hemodilution, blood . However, it can also disturb the fine balance that supports physiological birth. Early changes result in metabolic demands, increasing levels of pregnancy. In Pregnancy .
