Changes in maternal physiology during pregnancy
Cardiovascular and haematological changes begin as early as 4 weeks’gestation and are progressive. During pregnancy the plasma volume increases by 45%. This increase is mediated by a direct action of progesterone and oestrogen on the kidney causing the release of renin and thus an activation of the aldosterone renin-angiotensin mechanism. This leads to renal sodium retention and an increase in ...
متن کاملMaternal cardiovascular changes during pregnancy and postpartum in mice.
Genetically altered mice may provide useful models for exploring cardiovascular regulation during pregnancy and postpartum if changes in mice mimic humans. We found in awake ICR (CD-1) mice at 17.5 days gestation that hematocrit was reduced 18%, and the pressor response to intravenous angiotensin II was reduced ~33%. Arterial pressure in awake mice was 12% lower in early pregnancy (3.5 days) th...

متن کاملPnm-28: Longitudinal Changes of Maternal Anthropometric Indices: A Cohort Study in Women during Pregnancy and Postpartum
Background: Evaluation of fat distribution is a way to assessment of physical health. Waist to Hip Ratio and waist circumference are the simplest anthropometric measurements to be used to determine the obesity and related disorders in pregnancy. Today a close consideration is given to WHR and WC assessment in order to evaluate physical health in epidemiological studies. Materials and Methods: O...
متن کاملAlterations in physiology and anatomy during pregnancy.
Pregnant women undergo profound anatomical and physiological changes so that they can cope with the increased physical and metabolic demands of their pregnancies. The cardiovascular, respiratory, haematological, renal, gastrointestinal and endocrine systems all undergo important physiological alterations and adaptations needed to allow development of the fetus and to allow the mother and fetus ...
