13 Surprising Reasons Your Blood Sugar Spikes Even Without Sugar

5. The Unexpected Role of Dehydration

Dehydration can lead to elevated blood sugar levels by reducing the volume of blood, making glucose more concentrated. When dehydrated, the kidneys may not be able to flush out excess sugar effectively, leading to further increases in blood sugar. Additionally, dehydration can cause the release of stress hormones, which can also raise blood sugar. Ensuring adequate hydration is crucial for maintaining healthy blood sugar levels. Drinking enough water throughout the day and being mindful of factors that can lead to dehydration, such as hot weather or intense exercise, can help prevent unwanted blood sugar spikes.

6. The Connection Between Exercise and Blood Sugar

Exercise is generally beneficial for blood sugar control, but the type, intensity, and timing of exercise can have varying effects. High-intensity exercise can cause a temporary spike in blood sugar due to the release of stress hormones. However, regular exercise improves insulin sensitivity and helps lower blood sugar levels over time. Understanding how different forms of exercise affect your body can help you tailor your fitness routine to optimize blood sugar control. Balancing aerobic and resistance training, and timing workouts to complement your body's natural rhythms, can enhance the benefits of exercise on blood sugar levels.
