According to the American Diabetes Association, nearly 21 million people in the United States have diabetes, with about 90 percent to 95 percent having type 2 diabetes. Sugar, in the form of glucose, is the main source of fuel for body cells. The hormone insulin allows glucose in the blood to enter cells. In type 2 diabetes, either the body doesn't produce enough insulin or cells are resistant to effects of insulin.
Baseline Endothelial Reactivity was 1.88+/-0.7 (range 1.0-3.3), with 145/200 pts (72%)having endothelial dysfunction (less than 1.60). At 6 months, ER increased to 2.25+/-0.5 (range 1.2-3.6) (p<0.01). Only 40/200 (20%) remained with ED, but all had increased ER numbers. Ten pts stopped the polyphenols after a normal PAT; all developed ED on repeat PAT "
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
