Criteria for Diagnosis of DM * Testing must be repeated on separate day. FPG is the preferred test ** Symptoms of DM IFG = Impaired fasting glucose IGT = Impaired glucose tolerance Diabetes care 1997; 20 :7 FPG 126 mg/dL 110 mg/dL 7.0 mmol/L 6.1 mmol/L Impaired Fasting Glucose Normal 2-Hour PG on OGTT 200 mg/dL 140 mg/dL 11.1 mmol/L 7.8 mmol/L Diabetes Mellitus Impaired Glucose Tolerance Normal Diabetes Mellitus **

Choosing the “Best” Therapy--Type 2 First Step: Major Contraindications for Oral Agents Liver function and serum creatinine Serum creatinine > 2 mg/dL Serum creatinine mg/dL Serum creatinine <1.4 mg/dL Metformin contraindicated No liver disease consider other oral agents Liver disease select insulin No liver disease select Thiazolidinedione Liver disease select insulin no yes *Since oral agents pass through the placental barrier they should be avoided in pregnancy. Oral agents have not been tested in individuals <18 years of age. yes
