Physiological changes in pregnancy

Priya Soma-Pillay et al. Cardiovasc J Afr. 2016 Mar-Apr.

Abstract

Physiological changes occur in pregnancy to nurture the developing foetus and prepare the mother for labour and delivery. Some of these changes influence normal biochemical values while others may mimic symptoms of medical disease. It is important to differentiate between normal physiological changes and disease pathology. This review highlights the important changes that take place during normal pregnancy.
