Exercise helps you manage your blood sugar by making it easier for your body to turn sugar into energy.
But sometimes getting active can cause your blood sugar levels to drop too low (below 70 mg/dL), this is called hypoglycemia.
Here’s what you need to know.
Signs of Hypoglycemia (Low Blood Sugar)
- Hunger
- Shakiness
- Sweating
- Confusion
- Dizziness
- Anxiety
- Weakness
Before You Exercise
Check your blood sugar before you start your activity routine
- If your blood sugar is less than 90 mg/dL, have a snack containing 15 grams of carbohydrates, such as 4 oz. of juice (1/2 a cup) or 3-4 glucose tabs.
If your blood sugar is less than 70 mg/dL, treat with a fast-acting sugar, such as 4 oz. of juice or 4 glucose tablets. When blood sugar is above 70 mg/dL have a small snack of protein and carbohydrates to keep your level stable while you're exercising.
During Exercise
If you notice any signs of hypoglycemia (feeling shaky, sweaty or dizzy), stop exercising immediately and check your blood sugar.
- If your blood sugar is less than 70 mg/dL, treat with a fast-acting sugar and recheck in 15 minutes to make sure your blood glucose is back above 100 mg/dL before you continue.
- Keep some fast-acting sugar with you when you work out—like hard candy, a drink containing sugar, or glucose tablets.
Exercise is one of the most beneficial things you can do for your health. And by taking a few precautions, you can avoid hypoglycemia and stay safe while you work out.
