Diabetic Foot Ulcer Self Monitoring

An important part of the successful management of diabetic foot problems is close monitoring of blood sugar.

Blood Testing for Glucose

  • Monitor your blood glucose as directed.
  • Learn to use your glucose monitor correctly.
  • Daily home glucose monitoring is essential.
    • Try to keep your glucose level before meals between 70-110 mg/dl.
    • Two hours after meals, your glucose level should be less than 140 mg/dl.
  • Check your blood sugar before operating a motor vehicle. Raise your blood sugar level by eating, if it falls below 70 mg/dl.
  • Carefully monitor your blood sugars when you are ill. Blood glucose increases when you are ill or have an infection.

When to test your blood glucose:
  • Before meals
  • Before bedtime
  • 1-2 hours after meals
  • 2-3 A.M., at least one night per week

Other reasons to test:

Urine Testing for Ketones
In the past, urine testing was very useful and important. With the advent of rapid blood sugar testing, urine testing is usually not necessary. The main reason to perform this test is to check for early ketoacidosis. Small or trace ketones may mean nothing or represent the beginning of ketoacidosis. If you find this result, then perform the ketone test again in several hours. Notify your physician immediately if you discover moderate to large ketones present in your urine.
