Pregnancy, Lactation, Infants Flashcards
Pica
Craving/eating something normally not considered food
Problems that can occur in pregnancy
1) taste and smell change
2) nausea/vomiting
3) heartburn
4) constipation/hemorrhoids
5) taking herbs
6) vegetarian/vegan
7) food safety
Pagophagia
Craving ice, used to be freezer ice
Geophagia
Eating dirt, almost always clay
Amylophagia
Eating laundry starch
Tricophagia
Eating string and hair
Two deficiencies common in people with pica
Iron and zinc
Ways to help with nausea and vomiting
1) separate solids and liquids
2) have dry foods near bed and eat before getting up
3) small frequent meals
4) separate odors from food - leave during cooking, chill meals
5) if from supplements try a different brand
Drugs that can help with nausea
1) Vitamin B6 - 10-25 mg every 8 hrs
2) Ginger - 1 g/day for 4 days
3) multivitamin mineral tablets if were taking prior to pregnancy
4) diclectin - prescription drug
Ways to help with heartburn
Less caffeine Don't lay down after eating Sleep at an angle Avoid spicy foods Don't eat too much at one time Wear loose clothing Don't go to bed on a full stomach
Why heartburn during pregnancy
GI tract relaxes to absorb more nutrients and sphincters also relax allowing reflux
What meds can dietitians recommend for heartburn
Only TUMS - patient needs to see MD for anything else
Why constipation during pregnancy
Because GI tract relaxes
Things to help with constipation
Fiber
Fluids
Exercise
What is ok for dietitian to recommend for constipation
Only Metamucil - no drugs - need to talk to MD for drugs
How to avoid hemhorroids
Avoid constipation
When is an herb considered a drug
If it has an effect - must talk to an MD
Problems vegetarians/vegans can have during pregnancy
Low iron
Why is food safety important during pregnancy
Because immune system is decreased
Two bacteria of concern during pregnancy
1) Listeria monocytopenes - will cross placenta and cause birth defects - 25% of people have the antibody - comes from delis (slicer) and recommendation is to cook deli meat
2) toxoplasma gondii - from cat box, undercooked meat, unwashed fruits/veggies - causes blindness, seizures and termination
Listeria Monocytogenes
Bacteria of concern during pregnancy - 25% of people have the antibodies (ie, have been exposed)
Effects: crosses placenta and can cause birth defects and can cause termination
Causes: deli meats (contaminated slicer) , raw/undercooked eggs, raw meat, unpasteurized milk, soft cheeses (Brie, quest fresco) unless made with pasteurized milk
Toxoplasma gondii
Bacteria of concern during pregnancy
Effects: mental retardation, blindness, seizures, termination of pregnancy
Causes: cat litter box, undercooked meats, unwashed fruits/vegetables
Shoulder dystocia
Medical emergency that is often a complication of LGA babies
Head comes out but shoulder gets stuck, umbilical cord can get cut off
Placenta abruption (abruptivo placentae)
Placenta tears away from the uterus and causes mom to hemhorrage - can see bleeding or not - blood can pool behind the uterus
If placenta tears away prematurely and greatly mom can die and nutrients, oxygen can be restricted to the baby
Exercise during pregnancy recommendation
30 min/day
Benefits of exercise during pregnancy
- reduce constipation
- reduce backaches
- reduce bloating
- sleep better
- decrease risk of gestational diabetes
- better mood/positive outlook
- better able to cope with labor
- get back in shape easier
Conditions effecting pregnancy
Obesity
Bariatric surgery
Hypertensive disorders
Diabetes
Obesity during pregnancy
- weight loss not recommended during pregnancy because it disproportionately affects baby
- higher risk of gestational diabetes, hypertensive disorders, LGA babies, baby growing to be obese
Bariatric surgery and pregnancy
- common to get pregnant after because physical and mental barriers removed
- causes enormous malabsorption of nutrients - need a good nutrition assessment and biomarkers
- advised to wait 1-2 yrs before getting pregnant after bariatric surgery
Hypertensive disorders of pregnancy
- is a major killer of women worldwide
1) chronic hypertension
2) gestational hypertension
3) preeclampsia
4) eclampsia
Chronic hypertension
When you come into pregnancy with HBP
- Definition - greater than or equal to 140 diastolic or 90 systolic
- Treatment - same as before pregnancy - would have sodium restriction
- would me more likely to have preeclampsia and eclampsia, also placenta abruptiva
Gestational hypertension
- definition - when you develop HBP in the second half of pregnancy (after 20 weeks)
- similar to preeclampsia/eclampsia but without protein in the urine
Preeclampsia 4 warning signs
Hypertension
Edema
Protein in urine
Insulin resistance
Effects of preeclampsia
- Coagulation problems - blood clotting everywhere (liver, brain)
- mom is more likely to have hypertension and diabetes later in life
Preeclampsia treatment
- No one knows cause - thought maybe placenta not embedded in uterine wall and body rejects
- only cure is to get rid of the placenta - deliver baby
- disease usually goes away as soon as baby is delivered
- restricting sodium does not work
- antioxidants, fish oils, folic acid have no effect
- calcium and vitamin D supplements help IF the mom is low helps
- using multivitamin before pregnancy helps
- evidence that diet high in plant food helps
Eclampsia
Development of preeclampsia into seizure and imminent death
Consequences of uncontrolled diabetes on pregnancy
Preeclampsia, stillbirth, baby grows up to have hypertension and diabetes
When pregnant women tested for diabetes
Beginning of pregnancy - checking for undiagnosed DM
At 24-28 weeks - checking for gestational diabetes with oral glucose tolerance test
How pregnant women can manage diabetes with diet
- low simple sugars
- low glycemic index foods
- carb counting (10-20% breakfast; 20-30% lunch; 30-40% dinner; 30% snack)
- calories for normal weight gain
Two types of twins
1) identical (monozygotic) - after fertilized the egg splits
2) fraternal (dizygotic) - two eggs released and both fertilized
Weight gain for twins
Normal weight - 37-54 lbs
Overweight - 31-50 lbs
Obese - 25-42 lbs
Research shows for multiples
- folic acid is important
- morning sickness increases
- time in OB’s office increases
- placenta previa, preeclampsia and gestational diabetes increases
- C-sections increase
- low birth weight increases
Most common cause of children with HIV/AIDS
Vertical transmission from mom to fetus during pregnancy or from mom to infant during breastfeeding
Chance baby gets HIV/AIDS from mom with no med care
25-35%
Chance in US that baby gets HIV/AIDS from mom with med care
Less than 1%
Breast feeding recommendation if mom has HIV/AIDS
Don’t breast feed
Two types of laws about testing for HIV when pregnant
1) opt in - doc must tell you you should get tested but you have to sign a paper to have the testing
2) opt out - you get tested unless you sign a paper saying no
Colorado’s law on HIV testing for pregnant women
Opt out
Treatment during pregnancy and after baby is born if mom has HIV
- mom on combo of HIV drugs for entire pregnancy
- mom gets IV with anti-viral drug called AZT when goes into labor
- baby gets AZT orally for 6 weeks after birth
- baby gets tested 14-21 days; 1-2 m; 4-6 m
HIV drugs teratogenic
Certain are teratogenic for first trimester but not after - so have to see doc right away if might be pregnant
Protease inhibitors increase chances of hypoglycemia and diabetes
When c-section recommended for mom with HIV?
Only if mom not treated and has a high viral load
US policy on breastfeeding
All babies should be breastfed from birth to 1 year, and breastfed exclusively for the first 6 months. Breastfeeding can continue as long as mutually beneficial from mom and baby.
When does breast milk become nutritionally inadequate?
1 yr
Breast feeding and obesity
Breastfed babies are less likely to become obese
IBCLC
International Board Certified Lactation Consultant
- must be reimbursed for services under ACA
Lobules
Milk producing glands made of alveoli and eventually empty in multiple openings at nipple
Areola
Dark circle around nipple
Ducts are lined with
Myoepithelial cells
2 stages of breastfeeding
1) milk production
2) milk letdown (ejection)
Letdown
Myoepithelial cells contract and send milk towards the nipple
2 hormones involved in milk production
Prolactin and oxytocin
Prolactin function and location
Causes alveoli to make breastmilk.
Prolactin produced in hypothalamus and stored in anterior pituitary
Oxytocin function and location.
Responsible for letdown; causes uterus to contract, controls bleeding, helps uterus to return to normal size; “love” (bonding) hormone.
Produced in hypothalamus and stored in posterior pituitary
When has breast anatomy matured enough that breast feeding possible
16 weeks pregnant
When in pregnancy can breast feeding start and why
After placenta is gone because placenta puts out a hormone (maybe estrogen) that suppresses milk production
Lactogenesis means
Process of producing milk
3 stages of Lactogenesis
1) birth to 2-3 days: colostrum
2) 2-5 days: milk comes in
3) 10 days - mature milk
Colostrum is
First milk, yellow and thick due to beta-carotene. Filled with antibodies and growth maturation factors. Most important milk for the baby.
Watery and bluish milk
Mature milk
Foremilk and fat content
First milk that comes out. Will be lower in fat.
Hindmilk and fat content
Milk that comes out after foremilk. Has higher fat content.
Engorgement and how to treat
When milk comes in and overshoots. Best think to do is feed the baby so the milk amount can stabilize.
Amount of additional kcal required for breastfeeding
623 kcal. But mom should pull some of that from fat laid down when pregnant. Recommendation is to eat an extra 500 kcal/day for the first 6 m and an extra 400 kcal/day for 2nd 6 m.
Nipple care
Do not toughen
Clean with water - no soap or alcohol
Let air dry
