Before starting your routines of physical activity check your blood sugar levels
Before you start exercising, it’s very important for you to check with your doctor; they might ask you to get some tests first. Talk to your doctor about an exercise plan you can follow, explaining what kind and amount of physical activity you can do. Also, ask if you have any health problems that may limit your options. A doctor may advise you to make certain changes in your exercise plan, or make some adjustments in your diet and medication.
Remember that when you exercise, your blood glucose levels (blood sugar levels) go down, which is why you need to look out for Hypoglycemia (low blood glucose). It’s very important to get glucose plasma tests before exercising, and to always carry a fast absorption sugar source (sweets, sugar packets, glucose tablets, glucose gels, etc.), to counteract any Hypoglycemia that may occur.
If you do intense or prolonged exercise, it’s very important to check and follow your blood glucose levels up to 24 hours after doing such physical activity, to make sure there’s no Hypoglycemia or low blood glucose levels. When one does extreme exercises or prolonged physical activity for several hours, the cells use glucose reserves from the muscles (glycogen), and liver (glucagon). At the end of the exercise, both, muscles and liver, retain that glucose again for 24 hours, which is why blood glucose levels may decrease and cause Hypoglycemia.
People with Diabetes should take great care of their blood sugar levels while exercising. This is achieved by maintaining a balance between the glucose required to produce the energy needed for that physical activity, insulin action (injected or produced by the individual), and the glucose available in the foods you eat. On some occasions you might need extra food to keep that balance while you exercise.
If, however, your blood sugar levels are too high (Hyperglycemia), you should get a urine ketone test, because if you have ketones, you shouldn’t exercise since your blood sugar levels and ketones could rise even more.
