42
Blood pressure and blood flow changes in pregnant women
- Diastolic blood pressure drops slightly, 10-15mmHg - Supine hypotension in late pregnancy - Increase in WBC - Hypercoagulable state - Renal plasma flow increases by 30% to remove more metabolic waste - Blood pools in lower extremities as the uterus obstructs the inferior vena cava and the iliac veins
43
Respiratory System changes in pregnant women

44

- Unless the woman is nauseated the appetite increases. Food intake may increase 15-20% in early pregnancy - gingivitis and bleeding gums called epulis, which regresses after birth - ptyalism - Esophageal sphincter tone decreases causing heartburn - constipation - Liver is pushed up and alkaline phosphate levels are 2-4 times higher - Emptying time of gallbladder is slowed predisposing to gallstones.

ptyalism
excess saliva
