In diabetes, either the pancreas makes insufficient levels of insulin so cells absorb glucose poorly or cells themselves become insulin resistant and thus unable to absorb glucose despite adequate insulin levels. Both types of change increase blood sugar levels above normal. Parsed this way, type I and type II diabetes overlap some but also differ.
Keep your blood pressure under control. People with diabetes are more likely to have high blood pressure than are people who don't have diabetes. Having both high blood pressure and diabetes greatly increases your risk of complications because both damage your blood vessels and reduce blood flow. Try to keep your blood pressure in the range your doctor recommends, and be sure to have it checked at every office visit.
Diabetes doesn’t cause nearly as much of a stir in the media compared to HIV or cancer, but a few well-known names are associated with the disease – Halle Berry, Tom Hanks, and Paula Deen. And who doesn’t love that Food Network maven and American celebrity chef? Scandals aside, diabetes comes in two versions – Type I or Type II. In Type I, the pancreas decides to drop out of the physiological rat race and go on to discover its own metabolic purpose in life. As a result, the body generates little or no insulin, a hormone important in sugar metabolism. In Type II, unfortunate dietary choices, such as eating tons of sugar and carbohydrates, jam up the sugar absorption process, causing the body to become resistant to the insulin hormone. Type 2 makes up 90 percent of all cases of diabetes, which is going to be our focus here as we talk about when there will be a cure for diabetes. (Spoiler alert: Probably only after we ban the Big Gulp and the Big Mac.)

I am very excited by the closed-loop artificial pancreas trial which is now in its final stages. Professor Roman Hovorka at the University of Cambridge is currently perfecting an algorithm that enables a continuous glucose monitor and an insulin pump to talk to each other, and take over the delivery of insulin throughout the day and night, to keep glucose levels in range.
