What can the brain do if it needs more glucose but we keep the concentration of glucose too low using pharmaceutical drugs? It can increase the blood pressure! By clamping down on the arterioles to restrict the flow of blood so more of it is forced to go towards the brain, and by making the heart pump harder, the brain causes more blood to pass through it faster. Since the concentration of glucose in the blood is too low, the brain compensates by increasing the speed with which the available glucose passes through it. Alas, this desperate measure increases the risk of coronary artery disease and stroke.
In fact, there have been large studies whose intention was to prove that hypoglycemic drugs would improve the health of type 2 diabetics by lowering blood sugars to levels near normal; instead the patients began dying of heart attacks. At least one study was stopped early because of the deaths.
