Does blood sugar rise or fall during intense exercise?

Blood sugar falls during intense exercise.

When you exercise, your muscles use glucose (sugar) for energy. The more intense the exercise, the more glucose your muscles will use. This can cause your blood sugar levels to drop.

If you have diabetes, it's important to monitor your blood sugar levels before, during, and after exercise. This will help you avoid low blood sugar (hypoglycemia), which can be dangerous.

To prevent low blood sugar during exercise, you can:

* Eat a carbohydrate-rich snack before you exercise.

* Drink plenty of water during exercise.

* Stop exercising if you feel dizzy, lightheaded, or weak.

* Check your blood sugar level if you feel any of these symptoms.

If your blood sugar level is below 70 mg/dL, you should stop exercising and eat or drink something that contains carbohydrates. This will help raise your blood sugar level and prevent hypoglycemia.

If you have diabetes, you should always check with your doctor before starting an exercise program. They can help you develop a safe exercise plan that won't put you at risk for low blood sugar.
