Risk Factors for Prediabetes and Diabetes Mellitus Family history of diabetes Cardiovascular disease Overweight or obese state Sedentary lifestyle impaired glucose tolerance or impaired fasting glucose Hypertension Increased levels of triglycerides, low concentrations of
high-density lipoprotein cholesterol, or both History of gestational diabetes History of delivery of an infant with a birth weight >9
pounds Polycystic ovary syndrome Psychiatric illness
Criteria for the diagnosis of diabetes mellitus Symptoms of diabetes polyuria, polydipsia, and unexplained weight loss + casual plasma glucose concentration >200
mg/dl. OR FPG >126 mg/dl.
OR 2-hour postload glucose >200 mg/dl during
an OGTT (75 g anhydrous glucose dissolved in water).
“pre-diabetes”
FPG 100 mg/dl =normal ● FPG 100–125 mg/dl =IFG
(impaired fasting glucose high risk for development of
diabetes in these patient
PREVENTION OF TYPE 2 DIABETES MELLITUS
Perform screening with either the 2-hour oral glucose tolerance test or fasting plasma glucose test to establish a diagnosis of diabetes mellitus or to identify prediabetes mellitus • Initiate interventions that include lifestyle modifications
