What can excessive glucose in the blood result in?

Explanation:
Chronic high blood glucose damages small blood vessels and nerves. This microvascular injury, along with endothelial dysfunction, leads to reduced blood flow to distant tissues like the hands and feet. Over time, the poor perfusion can cause tissue ischemia and necrosis, and the nerve damage contributes to neuropathy. So excessive glucose in the blood is linked to vasoconstriction and damage that reduces flow to the extremities, causing necrosis and neuropathy. The other ideas—increased blood flow or no health effects—don’t fit with how prolonged hyperglycemia harms the vascular and nervous systems.
