A Comprehensive Guide on the Right Time for Blood Sugar Test

A blood sugar test is an essential component of managing diabetes. People with diabetes may, among other things, assist their doctor in making better-informed decisions about the type and dose of medicine they require by getting frequent blood sugar readings. You can use blood sugar testing to identify the meals, situations, and activities that cause your blood sugar levels to spike and fall.

It is crucial for people with diabetes to keep their blood sugar levels as near as possible to the normal range to prevent or postpone the onset of serious problems such as heart disease, vision loss, diabetic foot, and kidney disease.

Information from blood sugar testing helps manage diabetes. It can assist you in:

  • Keeping an eye on how diabetes drugs are affecting your blood sugar levels
  • Checking if the blood sugar level is high or low
  • Monitoring your progress
  • Recognizing the effects of other variables (such as sickness or stress) on blood sugar levels

So now the question is – how frequently blood sugar tests should be done? The current state of health and the demands of your everyday life significantly affect the response. For example, at least one blood sugar reading per day is recommended for people with type 2 diabetes. Some people might require testing up to seven times per day.

How is Blood Sugar Checked?

Blood Sugar Monitor

An enzyme-coated sheet of paper is used in blood sugar meters to react with the glucose in the blood. The meter also has an electrode that generates an electrical signal when it notices the glucose response. The electrical signal is then translated into a number by this signal. The number increases as blood glucose levels rise.

Continuous Glucose Monitor

Continuous glucose monitors (CGMs) are worn on the arm or abdomen beneath the skin. The CGM detects glucose levels in the fluid between your cells as opposed to the blood as a blood sugar meter does. The monitor receives the data from the sensor after that.

Right Time for Blood Sugar Test

Before Breakfast

A fasting blood sugar test, often done in the morning before you’ve eaten or drunk anything, can show you how effectively your body regulates blood sugar while you sleep. Additionally, it provides a baseline from which you may track daily fluctuations in your blood sugar.

Before Bedtime

You can determine if your blood sugar is in a healthy range or whether you need to have a snack before bed. Evaluating and understanding how your sugar levels alter overnight may also serve as a point of reference.

Before Each Meal

People who inject insulin can find out if they need to take an additional “correction dosage” of it in addition to their bolus dose to cover the meal. A pre-meal reading can serve as a reference for how the food you consume and any pre-meal medicines impact your glucose levels when testing in pairs (pre-meal and post-meal).

After Each Meal

The food you take has a significant influence on your blood sugar levels. Testing should be done one to two hours after a meal, according to the American Diabetes Association (ADA). Establish your goal after-meal glucose range in collaboration with your healthcare provider to ascertain whether your blood sugar level is within the normal range.

What Do Blood Sugar Test Results Mean?

Write down your results after the blood glucose test and note any possible influences, such as diet, activity, and stress. Check your glucose record carefully to discover whether your reading has been abnormally high or low several days in a row at around the same time.

If the same issue persists, it could be time to modify your diabetic treatment regimen. Learn what your findings imply for you by working with your doctor or a diabetes educator. It may take some time to refine and perfect a situation. Inquire with your doctor if you should call straight away to report findings that are outside of a specified range.

Remember, regular examinations can save patients from getting nephropathy, diabetic foot, diabetic neuropathy, etc. Consult your doctor about maintaining blood sugar levels within the desired range.

Diabetic Foot Problems Warning Signs

  • Alterations in skin tone
  • Skin temperature changes
  • Swelling in the ankle or foot
  • Leg discomfort
  • Open wounds that take a long time to heal
  • Fungus-infected toenails
  • Ingrown toenails.


People sensitive to diabetes might avoid disasters by routinely testing their blood sugar levels. For example, elevated glucose levels might be a sign of diabetes or a risk factor for it. Regular glucose checks can help patients avoid any issues. If you see any signs of hyperglycemia or hypoglycemia, speak with your doctor.
