Final answer:
Elevated glucose levels in the blood stream can cause imbalances in body fluids, excessive urination, excessive thirst, narrowing of blood vessels, infections, and delayed wound healing.
Step-by-step explanation:
Elevated glucose levels in the blood stream causes imbalances in body fluids. When blood glucose levels rise above normal, it can result in excessive urination and excessive thirst. The kidneys, responsible for filtering glucose from the blood, draw water into the urine to dilute the glucose, leaving the body dehydrated and causing increased urine production.
High glucose levels can also lead to glycosylation of proteins in blood vessels and capillaries, narrowing the passage of blood flow and potentially leading to conditions such as atherosclerosis. Additionally, high glucose levels can cause various infections and delay wound healing.
