Gestational Diabetes Mellitus (GDM) Flashcards
how is GDM defined?
defined as elevated glucose levels that are first recognized during pregnancy
In first trimester of pregnancy, uncontrolled hyperglycemia can affect what?
fetal development, resulting in malformations
Patients with GDM are at significant risk of developing what later in life?
glucose intolerance
Patients whose GDM is diagnosed early in pregnancy and who may be obese are at increased risk of:
sustained glucose intolerance and type 2 diabetes
complications of GDM?
pre-eclampsia or having a birth with shoulder dystocia, a Caesarean birth, or a LGA
GDM places the fetus at increased risk for:
hypoglycemia, IUGR(intrauterine growth restriction) (related to poor placental function), and intrauterine fetal death
is hyperglycaemia difficult to detect?
yes
when should pregnant patients should be screened for the presence of GDM?
24 to 28 weeks of gestation
when should pregnant patients be screened early (1st trimester) for hyperglycaemia?
if have extra risk factors
Risk factors for the development of GDM include:
Being 35 years of age or older
Being a member of a high-risk group (African, Arab, Asian, Latin-
American, Indigenous, or South Asian)
Using corticosteroid medication
Obesity (a body mass index [BMI] greater than or equal to 30)
Pregestational diabetes
Gestational diabetes in a previous pregnancy
Given birth to a baby that weighed more than 4 kg
A parent, brother, or sister with type 2 diabetes
Polycystic ovary syndrome or acanthosis nigricans (darkened
patches of skin).
If the initial screening (early screening) is performed before 24 weeks of gestation and is negative, when should there be a re screening?
between 24 and 28 weeks of gestation
Fasting (preprandial) blood glucose levels should be between:
3.8 and 5.2 mmol/L
1 hour after meals (postprandial) blood glucose levels should be between:
5.5 and 7.7 mmol/L
2-hour postprandial blood glucose levels should be between:
5.0 and 6.6 mmol/L
