Managing diabetes can seem overwhelming, but understanding your blood glucose levels makes it much easier. Let’s break it down in a way that’s easy to follow and even easier to stick with.
Why Testing is needed
Testing your own blood sugar is a key part of managing diabetes and it’ll become part of your everyday routine. Here’s why it’s important:
- It helps you keep your diabetes under control to avoid future health problems.
- It shows how well your medication is (or isn’t) working.
- It helps you avoid blood sugar that’s too high (hyperglycemia) or too low (hypoglycemia).
- It tells you how your diet, exercise, stress, travel, illness, and for women, menstrual cycles or menopause, affect your blood sugar.
- Too Low: Under 4 mmol/L (Under 72 mg/dL)
- Healthy Target: 4-7 mmol/L (72-126 mg/dL)
- High: Over 7 mmol/L (Over 126 mg/dL)
- Too Low: Under 4 mmol/L (Under 72 mg/dL)
- Healthy Target: 4-7 mmol/L (72-126 mg/dL)
- High: Over 7 mmol/L (Over 126 mg/dL)
- If you’re on tablets: once a day.
- If you’re on long-acting insulin: before breakfast and dinner.
- If you’re on long- and short-acting insulin: before meals, once a day two hours after a meal, and whenever you feel unwell.
- Before meals, bedtime, and exercise.
- When you’re sick or change medication.
- When you feel unwell.
