Hormones of pregnancy:

 Estrogen:Causes increased vascularity of the mucous membranes of the upper

respiratory tract. As the capillaries become engorged, edema and hyperemia develop

within the nose, pharynx, larynx, and trachea. This congestion may cause nasal and sinus

stuffiness, epistaxis (nosebleed), and deepening of the voice. It also causes edema of the

eardrum and Eustachian tubes may result in a sense of fullness in the ears. Also bleeding

gums, ptyalism (excess production of saliva), and decreased bladder tone.

 Progesterone: Keeps uterus and blood vessels relaxed and accommodates increased

blood volume that increases cardiac output but not the BP. Allows the bladder to hold

pregnancy. Increases the availability of glucose to the fetus. Prepares breasts for

lactation.
