    Let’s talk about the types of diabetes - type I, type II. Type I completely deficient of insulin. There are a couple of things here that I need to bring to your attention when I talked to you about pathogenesis, but for right now, stick with me here when I tell you with type I, IDDM, insulin dependent diabetes mellitus. Obviously, this patient is young and by young, look at the first… second column, excuse me, and you notice that it’s a age range of less than 30. So, when I say young, hmm, be careful. You’re reading this stem of a question or you’re reading the chart with chief complaint and your patient doesn’t have to be two, three or five years of age. They could be up until 25. So, even at the age of 25, you can have a patient that develops type I diabetes. Do not just think that just because insulin is not present that it only occurred in a child that was four or five years old and that’s where students and doctors tend to get this confused. You can still have a type I diabetic who develops it at the age in their 20’s regularly. Now, there is a genetic component that’s extremely important for you to pay attention to and 20 to 50 percent twin concordance, so quite a bit of association within twins and there is a HLA link. Now, with the type I diabetic, these individuals are not obese, none of these younger patients and they most likely are already on a pump, an insulin pump. If they never had insulin to begin with, how in the world could oral hypoglycemic drugs be effective? If there’s no insulin in the pancreas, now how can you give drugs to release the...
