Despite major advances in the treatment
of Type 2 diabetes, only a minority of
patients meets glycemic targets longer term
1) efficacy of present pharmacotherapy options
is limited
2) insulin secretory deficit increases progressively
3) pathophysiology is only partially understood
4) present pharmacotherapy may be burdened by
side effects
5) self management by the patient is mandatory, but
often a difficult challenge
because

IDF consensus definition (2005)*
Central Obesity
Waist circumference – ethnicity specific*
– for Europids: Male ≥ 94 cm
Female ≥ 80 cm
plus any two of the following:
Raised Triglycerides
≥150mg/dL (1.7mmol/L)
or specific treatment for this lipid abnormality
Low HDL Cholesterol
<40mg/dL (1.03 mmol/L) in males
<50mg/dL (1.29 mmol/L) in females
or specific treatment for this lipid abnormality
Raised blood pressure
Systolic : ≥130 mmHg or
Diastolic: ≥85 mmHg or
Treatment of previously diagnosed hypertension
Raised fasting plasma glucose
(FPG)
FPF ≥100 mg/dL (5.6 mmol/L)
or
Previously diagnosed type 2 diabetes
If above 5.6 mmol/L or 100 mg/dL, OGTT is strongly recommended but is
not necessary to define presence of the syndrome.
