Increases prolactin output (readies breasts for lactation)
estrogen Increased levels of (progesterone/estrogen) during pregnancy contributes to a
hypercoagulable state
Increases tidal volume (subjective SOB) What changes does increased progesterone during pregnancy cause? (3)
Lowers LES tone (GERD)

hCG; doubles every 48 hours until peak of 100,000 at 8-11 In addition to estrogen and progesterone, the placenta also produces _____ during
weeks pregnancy, which is used to test for pregnancy.
What should its rate of increase be?
increases (due to stimulation of TSH receptors by HCG); Thyroid function, and therefore T3/T4, physiologically (increases/decreases)
down during pregnancy. Therefore, the TSH goes (up/down)
Relaxin Hormone released during pregnancy responsible for remodeling of connective
tissue, which allows for the pelvis to widen to accommodate a growing uterus
both increase What happens to plasma volume and basal metabolic rate in pregnancy?
Enlargement Breast changes during pregnancy: (3)
Venous pattern becomes more prominent
Colostrum secreted in 3rd trimester
