Diabetes in a Nutshell

Exercise

The relationship between exercise and good diabetes control is an important one! When you engage in an aerobic exercise (and, to a lesser degree, resistance training), a lot happens to your body to make sure the working muscles have enough oxygen and fuel. You breathe deeper, your heart pumps faster, and your blood vessels allow more blood to flow into muscle tissues. This can lower your blood sugar because your body uses more energy to fuel the increased workload. Physical activity also makes your body more sensitive to the insulin you already have on board; thus you may see a decrease in blood sugar levels even a few minutes after walking.

Benefits of personal fitness for a person with diabetes: exercise

  • Decreases need for insulin and/or oral medication
  • Decreases insulin resistance and increases insulin sensitivity
  • Helps lower blood sugar levels
  • Helps control weight--especially with at least a half hour of aerobic exercise
  • Lowers triglycerides, the blood fats that contribute to clogged arteries
  • Increases HDL cholesterol, the good cholesterol that actually rids the bad cholesterol (LDL) in the blood stream
  • Two men working outImproves blood circulation throughout the entire body

Exercise precautions

  • Always wear medical identification.
  • Carry a fast-acting sugar--approximately 15 to 30 grams of carbohydrates.
  • Exercise with another person, especially when exercising for longer than an hour.
  • Plan exercise by adhering to the proper time, by eating extra food before strenuous exercise or by down-regulating your insulin dosage as recommended by your doctor or diabetes nurse educator.
