folic acid intake
-low risk - 0.4 mg daily for at least 2 to 3 months prior to pregnancy, throughout pregnancy, and during the postpartum period if breastfeeding. This amount is in prenatal vitamin
moderate risk - (diabetes, epilepsy, obesity, or first- or second-degree relative with history of NTDs): 1.0 mg daily for the 3 months prior to pregnancy and during the first trimester. Decrease dose to 0.4 mg after first trimester
high risk - (partner or self who has had an NTD or a previous pregnancy with NTD): 4 mg/day at least 3 months prior to conception and through the first trimester of pregnancy, after which time can decrease intake to 0.4-1.0 mg daily
foods high in folic acid
liver (chicken, turkey goose)
Spinach
Lentils
Beans
edamame
Nutrient Needs During Pregnancy
first trimester - same as pre pregnancy
second trimester - 340 kcal greater than pre pregnancy needs
third trimester - 452 kcal more than pre pregnancy needs
high BMI risks
macrosomia
Fetal pelvic disproportion
High risk of c section and pph
-Excessive weight gained during pregnancy may be difficult to lose after pregnancy, contributing to chronic overweight or obesity
-The patient who gains 18 kg or more during pregnancy is especially at risk.
protein
25 g/day more than normal
-Rapid growth of fetus, enlargement of uterus, placenta, mammary glands, increased blood volume, formation of amniotic fluid all require more protein
fluids
-Recommended daily intake 2.2 L
-Dehydration, can cause continuous braxton hicks and preterm labour
omega 3 fatty acids
-essential to fetal brain development and neurological function
- primarily found in fish, shellfish, fish oil supplements, and omega- 3-enriched eggs
-Low mercury fish
-150 g/day
iron intake
- RDA - 27 mg/day (take multivitamin with 16-20 mg)
- Take on empty stomach between meals
- Do not take with coffee, tea, milk
-Take vitamin C with iron to increase absorption
calcium
1000mg/day (constipation side effect)
vitamin D
2000 IU/day
caffeine
less than 300 mg/day
about 1 cup of coffee
Vegetarian diets
Vitamin B12 deficiency
nausea and vomiting
- Common in first and third trimester
- First line: Diclectin (high dose vitamin B)
- Second line: Gravol
constipation
20g fiber/day
Increasing activity and fluids
pyrosis
Small frequent meals
Avoid drinking fluids with meals → over distended stomach
Avoid spicy, high in fat, acidic foods (chocolate, mint)
Avoid lying down after eating
Add a source of protein to each snack
H2 antagonists (famotidine)
weight loss after pregnancy
-Breastfeeding moms lose 0.5-0.9 kg more per month than non breastfeeding
-Lose about 20 pounds immediately after having baby
Nutrient Needs During Lactation
- Nutrition needs during lactation are similar to those during pregnancy.
-Needs for energy (kilocalories), protein, calcium, iodine, zinc, the B vitamins, and vitamin C are greater than nonpregnant needs. - Small amounts of alcohol are okay
- Smoking decreases milk production
- Limiting caffeine (decreases iron production)
Recommended Infant Nutrition
- breastfed exclusively for the first 6 months of life.
-Breastfeeding provides optimal food for the infant.
-Vitamin D supplement until 1 year of age
-If infants are weaned before age 12 months, they should receive iron-fortified infant formula.
contraindications for breastfeeding
- Cancer treatment with radioactive isotopes
- Severe illness such as sepsis, psychosis, eclampsia or shock that prevents her from caring for her infant.
-Galactosemia in the infant
-Human T-lymphotropic virus. - Active TB
- Maternal HIV
- Breast has active herpes lesions (use other breast)
- Medications (high doses of antipsychotics or anti epileptics)
Baby-Friendly Hospital Initiative
-Joint effort of the WHO and the United Nations Children’s Fund (UNICEF) to promote and support worldwide breastfeeding as the model for optimum infant nutrition
-Ten steps that protect, promote, and support breastfeeding families
-Nursing care includes respecting parents’ feeding choices and supporting their learning about responding to infant needs.
-Training staff, pumping, rooming in for 24 hours, breastfeeding on demand, breastfeeding within 1 hour of birth, no pacifiers, referral to lactation consultant
Maternal Conditions That Permit Breastfeeding
-Breast abscess - Breastfeeding should continue on the unaffected breast
-Cytomegalovirus in mother
-Herpes simplex lesions - breastfeed on unaffected breast
-Hepatitis B - Babies should receive Hepatitis B vaccine within 48 hours of birth
-Hepatitis A or C – There is no definite case of mother to baby transmission via breast milk;
-Mastitis – infection in the milk duct. If breastfeeding is very painful, breast milk must be removed by expression to prevent progression of the condition;
- Substance use – Mothers should be encouraged not to use these substances
- A medical condition that may make it difficult to breastfeed more frequently, such as intolerable pain that is unrelieved by intervention.
lactogenesis
-Ductules enlarge into lactiferous ducts and sinuses, where milk collects behind the nipple
-After birth, a precipitate decrease in estrogen and progesterone levels triggers release of prolactin
-Prolactin levels highest during first 10 days after birth
-Prolactin produced in response to infant suckling and emptying of breasts
-Milk is constantly produced as the infant feeds.
-Oxytocin - Stimulated by infant suckling
-Responsible for milk ejection reflex (let down reflex) myoepithelial cells surrounding the alveoli respond to oxytocin by contracting and sending the milk forward through the ducts to the nipple
unique properties of human milk
-Human milk contains immunologically active components.
-Provide some protection against broad spectrum of bacterial, viral, and protozoal infections
-Secretory immunoglobulin A is the major immune globulin in human milk.
-Breast milk changes based on what age the baby is
colostrum
-More concentrated than mature milk
-Extremely rich in immune globulins
-Higher concentration of protein, fat-soluble vitamins, and minerals
-Less fat than mature milk
