Pre-Diabetes and Gestational Diabetes Flashcards
Pre-Diabetes
Higher than normal blood glucose
Patients are at high risk for developing DM and CVD
Two Types of Pre Diabetes
Before Meal (Impaired Fasting Glucose) Spike after a meal (Impaired Glucose Tolerance)
Pre-DM associated with:
Obesity
Dyslipidemia (High TG, Low HDL)
Hypertension
Risk Factors for Pre-DM
Family history of DM2 Age >45 y.o. AA, East Asian, Laatino, Pacific Islanders Obesity CVD HTN Dyslipidemia PMH of gestational DM Sedentary lifestyle Women with PCOA Suspected insulin resistance
Pre-DM Fasting Glucose
100-125
Pre-DM 2 hr Post-Glucose Load
140-199
Pre-DM A1c
5.7-6.4%
Screening for Diabetes in Asymptomatic Adults
BMI >25 and additional RF
>45 y.o.
Repeat every three years
Pancreas in T2 DM
Decreased insulin and amylin secretion and increased glucagon
Kidney in T2 DM
Decreased incretin secretion and action
Liver in T2 DM
Increased gluconeogenesis and insulin resistance
Fat in T2 DM
Increase lipolysis and insulin resistance
Muscles in T2 DM
Decreased glucose uptake and increased insulin resistance
Similarities between IFG and IGT
Caused by insulin resistance
Caused by defect in insulin secretion
IFG difference
Liver
Impaired glucose utilization Increased gluconeogenesis
IGT difference
Muscles
Impaired glucose utlization
Modifiable RF for T2DM
Overweight and obese
Sedentary lifestyle
IFG or IGT
Metabolic syndrome
Non-Modifiable RF for T2DM
Ethnicity Family history Age Gender PCOA Gestational DM
Metformin treatment for Pre-DM IF:
Obese BMI >35
<60 years old
Women with prior GDM
Gestational Diabetes
Glucose intolerance of variable severity with onset or first recognition during pregnancy
But, not DM recognized in the first trimester
Macrosomia
In a newborn
Birth weight above the 90th percentile on the intrauterine growth curve
Birth weight above 4500 g
Fetal complications
Still birth Aberrant fetal growth Hypoglycemia & hypocalcemia Bilirubinemia & polycythemia Respiratory complications Should dystocia
Screening
Pt with RF at first prenatal visits
Screen for GDM at 24-28 wks using a 75 g 2hr OGT
Diagnosis Criteria
24-28 wks 75 g glucose load
Fasting: >92
1 hr: >180
2 hr: >153
