Which factors can affect blood glucose levels?

The factors that can significantly impact blood glucose levels are closely linked to how the body processes and responds to glucose, which is influenced by various lifestyle and physiological factors. Diet plays a crucial role because the types and amounts of carbohydrates consumed directly affect blood sugar levels. Foods high in sugars can lead to rapid increases in glucose, while balanced meals can help maintain stable levels.

Exercise is another important factor; physical activity helps muscles use glucose for energy, lowering blood sugar levels in the process. When someone engages in regular exercise, their body's insulin sensitivity improves, leading to better blood glucose control.

Medications, particularly those related to diabetes management such as insulin and oral hypoglycemics, can also have a profound effect on blood glucose levels. Certain medications can increase or decrease glucose levels based on their mechanism of action.

Lastly, stress can elevate blood glucose levels due to the release of stress hormones such as cortisol and adrenaline, which can prompt the liver to produce more glucose. Collectively, these factors interplay to influence how the body regulates and manages blood glucose levels, making option B the most comprehensive and accurate choice.

Other options mention factors that have a lesser or more indirect impact on glucose regulation, such as hydration or temperature, which are not primary determinants of blood
