10 Signs of High Blood Sugar
High Blood Sugar Sign #6: Difficulty concentrating
Hyperglycemia can also affect the workings of the brain. This can impair concentration, information processing and memory. It may also cause mood change. These signs occur because the brain cannot access adequate amounts of glucose. However, with all the sugar in the bloodstream, why would this happen?
Body cells, including neurons, can only metabolise glucose once they pass through the cell walls. Insulin is responsible for carrying glucose into cells. If there is an inadequate level of glucose or the body has insulin resistance, little glucose gets into the cells. With little glucose, brain cells starve such that they cannot produce enough energy to carry out their functions.
