I only learned recently from my dietitian that different levels of exercise affect my blood sugar differently, which is true to my personal experience. Low intensity exercise tends to raise my blood sugars while medium and high intensity tends to lower it. I am still working on finding and committing to an exercise routine that works for me, but for now I enjoy jogging, hiking and going to the gym with my colleagues. To prevent hypoglycemia, I will snack prior to exercising if my blood sugar is below 8, or I will not exercise at that time. Normally I don’t measure my blood sugar during exercise, only before and after. Having a continuous glucose monitoring sensor is really convenient for helping to track the sugars during exercise though, especially during medium intensity exercises such as long hikes. During longer activities, I make sure to pack both sweets (fast-acting sugar) and energy bars (long-acting sugar) that I can snack on if I feel myself going low mid-way.
