Definition Diabetes mellitus is a complex metabolic disorder characterised by persistenthyperglycaemia due to relative or absolute deficiency of insulin or insulin resistance
TYPES of DIABETESType 1 Diabetes: 5 to 10% patients have type 1 diabetes.Type 2 Diabetes: 90 to 95% patient have type 2 diabetes. Other Types. GDM IGT IFG

Table 4—Criteria for testing for diabetes in asymptomatic adult individuals 1. Testing should be considered in all adults who are overweight (BMI 25 kg/m2*) and have additional risk factors: ● physical inactivity ● first-degree relative with diabetes ● members of a high-risk ethnic population (e.g., African American, Latino, Native American, Asian American, Pacific Islander) ● women who delivered a baby weighing 9 lb or were diagnosed with GDM ● hypertension (140/90 mmHg or on therapy for hypertension) ● HDL cholesterol level 35 mg/dl (0.90 mmol/l) and/or a triglyceride level 250mg/dl (2.82 mmol/l)
● women with polycystic ovary syndrome ● A1C 5.7%--6.4%, IGT, or IFG on previous testing ● other clinical conditions associated with insulin resistance (e.g., severe obesity, acanthosis nigricans) ● history of CVD 2. In the absence of the above criteria, testing diabetes should begin at age 45 years 3. If results are normal, testing should be repeated at least at 3-year intervals, with consideration of more frequent testing depending on initial results and risk status. *At-risk BMI may be lower in some ethnic groups
The foundation of our current practices in diabetes stems from large prospective studies, such as the UK Prospective Diabetes Study (UKPDS) and the Diabetes Control and Complications Trial (DCCT), which suggested that better control of blood glucose reduces complications

Clinical implications Algorithm encourages flexibility and clinical judgement in Type 2 diabetes treatment Algorithm is cautious in use of newer treatments Lack of head-to-head trials continues to impede informed comparisons of strategies In severely uncontrolled diabetes, lifestyle + insulin is preferred regimen Long-term ability to control diabetes or reduce cardiovascular complications still a concern
Advantages of Insulin Therapy Most clinical experience Most effective (lowering glycemia) Can decrease any level of elevated HbA1c No maximum dose of insulin beyond which a therapeutic effect will not occur Beneficial effects on triglyceride and HDL cholesterol levels Nathan DM et al. Diabetes Care 2006;29(8):1963-72.
Why Aren’t Patients Achieving Blood Glucose Goals? Physicians not setting appropriate glycemic targets Type 2 diabetes is progressive - what works now may not work in the future Type of medications used are not appropriate Insulin therapy only used as a “threat”

TAKE HOME MESSAGE “Insulin should not be the treatment of last resort for manyof our patients, but should be thetreatment of best resort. Starting insulin is always resisted. A lotdepends on the clinician to handlethe different situations in a tactful way”
TAKE HOME MESSAGE DIABETES”S therapy should be individualized and adjusted according to the changing needs of the patients
