Question 1 • What is our Global Ranking for DM ? • What is our current estimated burden? • Why is T2DM so important ?
Question 1 • What is our Global Ranking for DM ? • What is our current estimated burden? • Why is T2DM so important ? • Numero Uno – RANK ONE Globally • About 36 million (in 2003) • DM = CAD + Its major complications !! • Shortens longevity by 10-15 years

Question 4 • What are the core defects of Insulin Secretion in T2DM ?
Question 4 • What are the core defects of Insulin Secretion in T2DM ? • Loss or delay of first phase of Insulin secretion • Blunting or flattening of second phase
Question 5 • What is Gold Standard Test to Diagnose DM ? • Should we use Plasma Sugar or Whole blood Sugar for Diagnosis ?
Question 5 • What is Gold Standard Test to Diagnose DM ? • Should we use Plasma Sugar or Whole blood Sugar for Diagnosis ? • O-GTT – Fasting sample and 2 hours Post Glucose (75g) sample • Obviously Plasma (venous sample)
Question 6 • What is Normal FBG & What is IFG ? • What is Normal PPBG & What is IGT ? • Is it essential two have TWO readings ?
Question 6 • What is Normal FBG & What is IFG ? • What is Normal PPBG & What is IGT ? • Is it essential two have TWO readings ? • N =100 mg FBG; 101-125 is IFG • N =140 mg PPBG; 141-199 is IGT • YES – Two readings are a must for Dx. • FBG 126 or PPBG 200 is DM

Question 7 • Can we use urine sugar for Dx. or F/u ? • Can we use HbA1c for Diagnosis ? • What is important in urine exam in DM ? • No. Urine sugar is not all useful • No. HbA1c is not for Diagnosis; only F/u • Albumin, MAU, Ketones are very imp.
Question 8 • What is the cause of Fasting Hyperglycemia ? • What is the defect that causes it ?
Question 8 • What is the cause of Fasting Hyperglycemia ? • What is the defect that causes it ? • Increase in Hepatic Glucose Output – Called HGO • Decrease in Basal Insulin secretion
Question 9 • What is the cause of Postprandial Hyperglycemia ? • What is the defect that causes it ?
Question 9 • What is the cause of Postprandial Hyperglycemia ? • What is the defect that causes it ? • Decrease in peripheral utilization – removal of glucose by muscle & adipose tissue • Excess CHO meal load • Delay or absence of 1st Phase Insulin
Question 10 • What are the four mechanisms which contribute to ↑ plasma glucose ?
Question 10 • What are the four mechanisms which contribute to ↑ plasma glucose ? • Hepatic Glucose Output (HGO) Basal In • Lack of peripheral utilization (IR) • Decrease in insulin secretion (ID) • Increase in absorption from GIT
Question 11 • What is HbA1c ? • What is its normal value ? • What does it reflect ?
Question 11 • What is HbA1c ? • What is its normal value ? • What does it reflect ? • It is a Glycated hemoglobin • Normal HbA1c is around 6% • It represents the mean plasma glucose over the previous 120 days

Question 18 • What is total metabolic control ?
Question 18 • What is total metabolic control ? • Glycemic control is essential but we also need to control all components • We must maintain the B.P <130/80 • The lipids under target values • See that pt. avoids smoking • Reduce his weight and waist • This is total METABOLIC CONTROL
Question 19 • List the microvascular complications
Question 19 • List the microvascular complications • Diabetic Retinopathy (DR) • Diabetic Kidney Disease (DKD) – Nephropathy • Diabetic Neuropathy – DPN, DAN These start right at the onset of ↑ BG We must screen for and prevent them
