Talk with your doctor about adjusting your rapid-acting insulin or other short-acting diabetes medications before workout sessions that usually lead to a glucose rise.

The same workout done later in the day is less likely to result in a rise. The dawn phenomenon, a natural rise in blood glucose that occurs between about 4:00 and 8:00 a.m., can result in higher levels during morning exercise.

Consider moving your workout to later in the day if you usually exercise in the early mornings.

Practice relaxation techniques such as paced breathing, visualization, or meditation before and during your workout to minimize the adrenaline effect.

Choose moderate-intensity aerobic workouts, or circuit weight training with light weights and high repetitions.

But if you’d rather avoid it altogether, here are some strategies that might help: Now that you know what causes a blood glucose rise after or during exercise, you may expect and accept it during your next workout session because you know the benefits of exercise outweigh the rise in glucose. Strategies to Keep Blood Glucose (Blood Sugar) From Rising During Workouts Eat too many carbs before exercising, and your sweat session may not be enough to keep your blood glucose within your goal range. The food you eat before or during a workout may also contribute to a glucose rise. Adrenaline raises blood glucose levels by stimulating your liver to release glucose. Some workouts, such as heavy weightlifting, sprints, and competitive sports, cause you to produce stress hormones (such as adrenaline). But you might see blood glucose go up after exercise, too. That’s why blood glucose levels usually come down during exercise. Using your muscles helps burn glucose and improves the way insulin works. Adrenaline Can Raise Blood Glucose (Blood Sugar) Levels Fear not! There are steps you can take to avoid this. But some people, after certain types of exercise, notice that their glucose levels actually rise during or after exercise.

Most of the time, working out causes blood glucose to dip. Being active most days of the week keeps you healthy by reducing long-term health risks, improving insulin sensitivity, and enhancing mood and overall quality of life. Exercise is essential for everyone-especially for people with diabetes.
