            Pregnancy
                           January 2006 Edition
      Physiology: Handouts
   Training Web Page
    www.agriculture.purdue.edu/healthybaby
   Training Section
      Powerpoint slides for streaming videos

      Training evaluation

   Research Update Section
      Physiology

         How your body changes

         Normal physiological changes

         Warning Signs
Normal Pregnancy Changes

 Regulate maternal metabolism
 Promote fetal growth
 Prepare mother for labor, delivery
  and lactation

 Many changes occur before they
  are needed – begin 8 days after
  conception
 Most are controlled by hormones
Blood Volume/Composition

    at 6-8 weeks
   28 wks – 40%; 30-34 wks – 50%
      60

      50

      40

      30

      20

           4 wks   12 wks   20 wks   24 wks   34 wks
Blood Volume/Composition
   Purpose:  nutrients and oxygen to
    baby
   As volume  concentration of nutrients
    
   Albumin  plasma pressure changes
   Leads to mild edema – this is normal
   Sudden increase in weight/edema – not
    normal – see health care provider
Respiration (breathing)
 Oxygen needs  (20-30% )
 Estrogen causes  in small blood
  vessels in nose, bronchi, etc
 Can become congested
 Stuffy nose, mild nosebleed,
  earaches may be normal
 Shortness of breath after 1st
  trimester is normal
Renal (Kidney)
  demands cause kidneys to filter
  more maternal and fetal waste
 Blood flow through kidneys  by
  35-60%
 Leads to  urination
Gastrointestinal (Gut) Function
   progesterone -  tone and
   movement of muscle in GI tract
  Leads to heartburn
   in water absorption from colon
   leads to constipation
  Constipation also related to size of
   growing fetus
  Taste and saliva changes
         Warning Signs
 Menstrual-like cramps
 Low – dull backache
 Pelvic pressure
 Abdominal cramping
 Change in vaginal discharge
 Bleeding from vagina
 Water from vagina
 Uterine contractions
              Summary
   Many things are normal during
    pregnancy – however, some signal
    problems

   If in doubt, check with your
    healthcare provider
Reminders
   Suggested next training video: Nutritional
    Requirements During Pregnancy
      Print out handouts from Research Update
       section: Nutrition
         Nutrition handouts

         Nutrition presentation

         Nutrition presentation clarifications

   Nutrition Update - January 2006
   Complete postevaluation after viewing all
    subject matter videos
   Email Donna Vandergraff,
    vandergraff@purdue.edu when done
