How can regular exercise impact type two diabetes?

1. It increases insulin production

2. It can help regulate blood sugar levels

3. It creates an insulin dependency

4. It causes permanent insulin resistance

The correct answer is: It can help regulate blood sugar levels

Regular exercise can significantly impact type two diabetes by helping to regulate blood sugar levels. When a person engages in physical activity, their muscles utilize glucose for energy, which helps to lower the amount of sugar in the bloodstream. This process not only aids in the immediate management of blood sugar levels but also enhances insulin sensitivity over time. Improved insulin sensitivity means that the body can use insulin more effectively, leading to better control of blood glucose levels. In addition to regulating blood sugar, regular physical activity also contributes to weight management, which is crucial for individuals with type two diabetes since excess weight can exacerbate insulin resistance. Exercise can also promote overall cardiovascular health, which is particularly important for those living with diabetes, as they are at higher risk for heart disease. The other choices do not accurately reflect the effects of regular exercise on type two diabetes. For instance, while exercise may influence insulin production, it does not solely increase it, and regular exercise does not create dependency or cause permanent insulin resistance. Instead, it helps combat these issues.
