This illustration shows what actually happens inside the bloodstream when glucose builds up. Normally, insulin acts as a key that unlocks cells, allowing glucose to move out of the blood and into body tissues where it is used for energy. When the body does not produce enough insulin or becomes resistant to its effects, glucose remains trapped in the bloodstream instead of being absorbed by cells. Over time, excess glucose begins attaching to proteins within blood vessel walls, causing them to become stiff, inflamed, and less efficient at delivering oxygen and nutrients throughout the body. As blood sugar levels continue to rise, circulation becomes less efficient...
