,UNIT 1: PHYSIOLOGICAL CHANGES IN PREGNANCY
Dynamic changes take place in the body of a pregnant woman in order to
maintain the pregnancy and accommodate the growing foetus, nourish the
foetus during the period of growth provide the woman with energy for delivery
and prepare for lactation
UTERUS
Increase in size 7.5x5x 2.5cm to 30x23x20 cm
Increase in weight 50 -60 g to 900 -1000g
Increase in volume 6ml to 5000ml
Upper portion of the body containing the blastocyst enlarges and is called
the upper uterine segment
The lower portion of the uterus adjacent to the cervix called isthmus
softens and lengthens in early pregnancy
After the first trimester the elongated isthmus is drawn up and forms the
lower uterine segment
At 12 weeks the uterus can be felt above the pelvis
CERVIX
In second trimester the cervix widens and softens and secretes mucus
which forms a mucus plug- this act as a barrier for against ascending
infections
Later the cervix becomes partly effaced(taken up) due to Blackston Hicks
contractions
the cervix changes from pink to dark purplish colour
The blood supply to the uterus increases with uterine growth. At term
blood flow ranges from 500mls to 700mls
VAGINA
3
, The muscles fibres of the vagina hypertrophy during pregnancy. The
vagina develops a larger lumen and increase in the ability to stretch. It
becomes very vascular and becomes dark purplish
VULVA
Increases in vascularity resulting in a darker colour. Vulva veins may
occur
FALLOPIAN TUBES
Hypertrophy and become more vascular
As the uterus grows they are lifted out of the pelvis
OVARIES
The blood supply increase and they are drawn up into the abdominal
cavity
BREASTS
3 to 4 weeks- there is a pricking and tingling sensation. The ducts and
alveolar system enlarge due to oestrogen and progesterone
6 weeks to 8 weeks breasts increase in size and vascularity
12 weeks the nipples enlarge and become more prominent
16 weeks there is secondary areola
Colostrum can be expressed
THE SKIN
Due to hormones there is increase in pigmentation on the face its called
chloasma
Linea nigra develops( darkening of a thin line extending from the
syphysis pubis to the umbilicus
Stria gravidarum develops-(rapid stretching of the skin of abdomen,
thighs and breasts
CARDIOVASCULAR SYSTEM
The heart
