Change and adaptation in pregnancy

Abstract

First paragraph: The anatomical and physiological adaptations occurring throughout pregnancy affect virtually every body system. The timing and intensity of the changes vary between systems but all are designed to support fetal growth and development and prepare the mother for birth and motherhood. The midwife’s appreciation of the normal adaptations to pregnancy and recognition of abnormal findings are fundamental in the management of normal as well as high risk pregnancies, enabling her to provide appropriate midwifery care to all women including those affected by pre-existing illness. A common feature of these changes is the dynamic and symbiotic partnership between the uteroplacental unit and the mother, which is influenced by physical, mechanical, genetic and hormonal factors. Many aspects of the physiology of pregnancy remain poorly understood and controversies continue to be researched.
