Physical activity includes all movement that increases energy use, whereas exercise is planned structured physical activity. Exercise makes our bodies more sensitive to insulin, that includes insulin made by our body or injected. Greater insulin sensitivity makes its action more efficient.

When you have diabetes, physical activity is an important component of your treatment plan.
Diet, exercise, and medication are the cornerstones of diabetes management.
People with diabetes have too much glucose in their blood, either because their body doesn’t produce enough insulin to process it, or because their body doesn’t use insulin properly (insulin resistant)

Exercise lowers the blood sugar in the following ways:

  • Insulin sensitivity is increased so your muscle cells are better able to use any available insulin to take up glucose during and after activity.
  • When Muscles contract during any activity, they can use glucose for energy even if insulin is not available.

The effect physical activity has on your blood glucose will vary depending on the duration, intensity of activity and many other factors. People taking insulin or insulin secretagogues are at an increased risk of hypoglycemia if insulin dose and carbohydrate intake are not adjusted with activity levels.

Does it matter when you exercise?

There’s no best time of the day when it comes to exercise. The best time to exercise is when it fits into your schedule. But stick to the same time and be consistent so that you become familiar with how your blood glucose responds to exercise.
30 mins of aerobic exercise at least 5 days a week is recommended.

Handy Tips before you start:

  1. Get your doctor’s OK
  2. Check your blood sugar
  3. Hydrate well
  4. Carry a carb to avoid hypoglycemia eg. fruit, dried figs, glucose biscuits, rock sugar, fruit juice (1/2 glass)
  5. Start slow and increase gradually
  6. Stop immediately if you feel low
  7. Make it a habit
  8. Go Public
  9. Don’t miss working out more than 2 days in a row
