Gestational Diabetes mellitus (GDM)
-woman experiencing gestational diabetes should be reclassified when?
6 weeks or more after the pregnancy
ends
-during normal pregnancy, glucose is the primary fuel used by the fetus and is transported across the placenta through the process of carrier-mediated facilitated diffusion.
-this means that the glucose levels in the fetus are directly proportional to maternal levels.

true or false
true
insulin or glucose
-which one crosses the placenta?
-glucose crosses the placenta,
around the ___ week of gestation, the fetus begins to secrete its own insulin at levels adequate to us the glucose obtained from the mother.

-therefore, as maternal glucose levels rise, fetal glucose levels are (increased or decreased), resulting in (increased or decreased) fetal insulin secretion
10th

increased
increased
during the 1st trimester of pregnancy, the pregnant woman’s metabolic status is significantly influenced by what?
the rising levels of estrogen and progesterone.
what stimulate beta cells in the pancreas to increase insulin production, which promotes increased use of glucose and decreased blood glucose with fasting levels being reduced.
estrogen and progesterone.
-as a result of these normal metabolic changes of pregnancy, women with insulin dependent diabetes are prone to hypoglycemia during what semester?
the 1st trimester

-a concurrent increase in tissue glycogen stores and a decrease in hepatic glucose production occur, which encourages lower fasting glucose levels.
when there is a decreased tolerance of glucose, increase insulin resistance, decreased hepatic glycogen stores, increased hepatic production of glucose. increasing levels of human chorionic somatomammotropin, estrogen, progesterone, prolactin, cortisol, and insulinase increase insulin resistance through their actions as insulin antagonists. insulin resistance is a glucose sparing mechanism that ensures an abundance supply of glucose for the fetus.
-during the 2nd and 3rd trimesters
maternal insulin requirements may double or quadruple by the end of the pregnancy.

true or false
true

-maternal insulin requirements gradually increase from 18-24 weeks of gestation to about 36 wks of gestation.
-at birth, expulsion of the placenta prompts an abrupt decrease in levels of circulating placental hormones, cortisol and insulinase. maternal tissues quickly regain their prepregnancy sensitivity to insulin
-at birth, expulsion of the placenta prompts an abrupt decrease in levels of circulating placental hormones, cortisol and insulinase. maternal tissues quickly regain their prepregnancy sensitivity to insulin
-from the nonbreastfeeding mother , the prepregnancy insulin balance usually returns in how many days
7-10
-lactation uses maternal glucose so breastfeeding mothers insulin requirements will remain high during lactation.

true or false
false, they remain low
Changing insulin needs during pregnancy

-first trimester:

tell me about the insulin need
-why?


what contributes to hypoglycemia?
-first trimester: insulin need is reduced because of increased insulin production by pancreas and increased peripheral sensitivity to insulin.


n/v and decreased food intake by mother and glucose transfer to embryo or fetus contribute to hypoglycemia
Changing insulin needs during pregnancy

-second trimester: insulin needs
- insulin needs begin to increase as placental hormones, cortisol and insulinase act as insulin antagonists, decreasing insulin’s effectiveness
Changing insulin needs during pregnancy

-3rd trimester: insulin needs may double or quadruple by usually level off after 36 wks of gestation

true or false
true
Changing insulin needs during pregnancy

-day of birth: maternal insulin requirements (increase or decrease) drastically to approach prepregnancy levels
decrease
-breastfeeding mother maintains (lower or higher) insulin requirements than those of prepregnancy, insulin needs of nonbreastfeeding mother return to prepregnancy levels in 7-10 days
lower
-weaning of breastfeeding infant causes mother’s insulin needs to return to prepregnancy levels

true or false
true
-poor glycemic control around the time of conception and in the early weeks of pregnancy is associated with
an increased incidence of miscarriage
-poor glycemic control later in pregnancy, increases the rate of
fetal macrosomia


-macrosomic infants tend to have a disproportionate increase in shoulder and trunk size, so the risk for shoulder dystocia is greater and have an increase of the likelihood of c sections or of operative vagina birth (use of episiotomy, foreceps, or vacuum extractor)
-hydramnios (polyhydramnios)- amniotic fluid in excess of 2000 ml is associated with: (3)
premature rupture of membranes,

onset of preterm labor,

postpartum hemorrhage
-infections are more common and more serious in diabetic pregnant women (vaginal infections and UTIs)

true or false
true

-infection is serious b/c if causes increased insulin resistance and may result in ketoacidosis
-postpartum infection is more common in woman who are insulin dependent
-disorders of what alter the body’s normal resistance to infection
carbohydrate metabolism
-ketoacidosis (accumulation of ketones in the blood resulting from hyperglycemia and leading to metabolic acidosis) occur most often when?
during the second and third trimesters
-when the maternal metabolism is stressed by illness or infection, the woman is at increased risk for what
DKA
the use of what to treat preterm labor may contribute to hyperglycemia and DKA and DKA may also occur as a result of the woman’s failure to take insulin appropriately
-the use of tocolytic drugs such as terbutaline
-what may occur with blood glucose levels barely exceeding 200 mg/dl, compared to 300-350 mg/dl in the nonpregnant state
DKA
-in response to stress factors such as infection or illness, what occurs as a result of increased hepatic glucose production and decrease peripheral glucose use
hyperglycemia (excess glucose in the blood)
ketoacidosis occurring at any time during pregnancy can lead to intrauterine fetal death. it is also a cause of
preterm labor
-early in pregnancy, when hepatic production of glucose is diminished and peripheral use of glucose is enhanced, hypoglycemia occurs frequently, often during sleep.
-later in pregnancy, hypoglycemia may also result as insulin doses are adjusted to maintain euglycemia (a normal glucose level)
-what is typically observed in pregnancies after 36 weeks of gestation in women with vascular disease or poor glycemic control
stillbirth
-the most important cause of perinatal loss in pregestational diabetic pregnancy is
congenital malformations
Diabetes
-anomalies commonly seen in infants primarily affect what 3 systems?
cardiovascular system,
CNS,
skeletal system
how does macrosomnia result
-the fetal pancreas begins to secrete insulin at 10-14 weeks of gestation. the fetus responds to maternal hyperglycemia by secreting lg amounts of insulin (hyperinsulinism). insulin acts as a growth hormone, causing the fetus to produce excess stores of glycogen, protein, and adipose tissue, leading to increased fetal size or macrosomnia
-macrosomnia is a wt greater than ___grams
4500
-macrosomic infant is at risk for
fractured clavicle, liver or spleen laceration,
brachial plexus injury,
facial palsy,
phrenic nerve injury,
subdural hemorrhage
-infants of mothers with diabetes are also at increased risk for
respiratory distress syndrome
-hyperglycemia and hyperinsulinemia may be instrumental in delaying _________maturation of the fetus
pulmonary
-for infants born to diabetic women, the transition to extrauterine life is often associated with ________abnormalities
metabolic
within 30-60 minutes after birth, neonatal hypoglycemia often occurs. why?
this is caused by the interruption of the glucose supply with the cutting of the umbilical cord, the effects of fetal hyperinsulinism, and the rapid use of glucose after birth
