Breastfeeding Trivia
“If all babies were breastfed
exclusively for their first six months of
life and then given nutritious
complementary food with continued
breastfeeding up to two years of age,
the lives of an additional ________
children under five would be saved
every year.”
Dr Elizabeth Mason, Director of WHO's Department of
Maternal, Newborn, Child and Adolescent Health and
American Academy of Pediatrics
Human milk is the preferred feeding for
all infants, including premature and sick
newborns, with rare exceptions.
Exclusive breastfeeding for the first six
months and support for breastfeeding for
the first year and beyond as long as
mutually desired by mother and child.
The World Health Organization
Recommends continued breastfeeding
up to 2 years of age or beyond.

Human Milk Is Adaptable!!
During a feeding, breast milk changes from low fat to higher
In cold climates breast milk has increased fat for energy, in
hot climates, more water to prevent dehydration.
During gradual weaning, breast milk volume decreases, but
the antibodies in the milk increase.
Mothers of premature babies make milk that is higher in
growth factors, protein and fats.
Mothers who are malnourished produce slightly less milk, but
the milk is equal in fat, protein and carbohydrate.

Breastfeeding & Diabetes
Why is breastfeeding particularly
good for the mother with DM and
particularly good for the infant from a
mother with Diabetes? (IDM)
Good for the Mother
Improved Glucose Metabolism
Non-insulin mediated use of glucose by
mammary gland to synthesize lactose.
Increased insulin sensitivity due to
increased prolactin and decreased
Improved B cell function with 3 months
of breastfeeding in women with GDM
Good for the Mother
Improved Lipid
Women who have
breastfeed for at
least 3 months
LDL levels
increase less
HDL levels
decrease less
Good for the Mother
Improved Weight Loss
Prospective studies using measured
weight change reported lower
postpartum weight retention in lactating
Rate of metabolic syndrome is sig lower
with increasing lifetime duration of
Good for the Mother
Lower rate of DM2 in Women who
Duration of lactation inversely
associated with risk of DM2 in young
and middle aged women
Non-lactating women developed DM2 at
a 2 fold higher rate than lactating women
after GDM.
Good for the IDM
Breastfed Infants are Leaner
Inverse relationship between
breastfeeding and development of
Formula fed infants produce more insulin
Hyperinsulinemia retards lipolysis and
enhances fat deposit.
Good for the IDM
Less Overfeeding: changes in breast
milk composition during feeding
provide satiety signals to the infant
Breast milk contains leptin- early
leptin intake can influence later eating
Fetal Origins of Adult Disease
The b-cells of the fetal pancreas become
more responsive to glucose late in
gestation and b-cell mass increase in the
last trimester of pregnancy
Theory:A high availability of glucose
programs pancreatic islet development
irreversibly influencing the metabolic
response to glucose later in life and
predisposing to certain patterns of adult
What is newborn Hypoglycemia?
Refers to a
reduction in the
concentration of
circulating blood.
Still controversialno consensus on
cut off values
Avoiding Newborn Hypoglycemia in
the IDM
Achieve normoglycemia during
pregnancy and LABOR
Terbutaline and ephedrine can cause
maternal hyperglycemia and
subsequent fetal hyperinsulinemia.
Avoiding Newborn Hypoglycemia
Breastfeed Immediately or within 30
minutes after birth, 10-12x/24hr
Cold wet babies use more glucose- Dry
thoroughly and place skin to skin ASAP
Encourage frequent feeds until BG >
45mg/dL BEFORE feedings.
Monitor infant BG for at least 24hrs or until
stable for at least 3 consecutive feedings.
Medically Necessary Separation
Provide EXTRA Support for
establishing breastfeeding
Use Pump within first 12 hrs
Modern Pumps Are Amazing!
Avoiding Maternal Hypoglycemia
Glucose preferentially shunted
towards production of milk
DM1(rarely DM2) prone to
hypoglycemia especially at night
May have to adjust evening dose of
basal insulin- Bedtime Snack Necessary
Avoiding Maternal Hypoglycemia
If BG <100 BEFORE feeding take 15g
CHO and 7 g protein.
If BG < 100 AFTER feeding consider 15 g
snack if insulin on board.
Hypoglycemia causes release of
epinephrine which can cause temporary
decrease in milk production.
Healthy Eating During Lactation
No surprises- Follow GDM meal plan!
May add fruit/milk at breakfast
May add cereal to breakfast
May add:
2 fat servings, 1 fruit and 1 starch to support
extra calorie needs during breastfeeding
Drink Plenty of WATER
Avoid Juices and Sweetened Drinks
Challenges to Breastfeeding
Women with DM less likely to
Difficult labor
Obesity interfering with body mechanics
Fear of giving diabetes through breast
Need to continue insulin and “tight”
control of BG
Lack of support
Lack of Societal Acceptance
