Why is it important to maintain normal blood glucose levels?

Maintaining normal blood glucose levels is crucial because glucose serves as a primary source of energy for the body's cells. It is particularly important for the proper functioning of various metabolic processes that sustain life. When blood glucose levels are within a normal range, the body can efficiently utilize this energy for cellular functions, muscle contractions, brain activity, and overall metabolic management.

When blood glucose levels are too low (hypoglycemia), the body may not have enough energy to perform essential functions, potentially leading to symptoms such as confusion, weakness, and in severe cases, loss of consciousness. Conversely, when blood glucose levels are too high (hyperglycemia), it can lead to a range of health issues, including long-term complications such as damage to blood vessels, nerves, and organs. Therefore, maintaining stable blood glucose levels is vital for energy balance, metabolic regulation, and overall health.
