Importance of regular monitoring of blood glucose

 In Diabetes, Health

The major part of managing diabetes is controlling blood glucose levels. Blood glucose levels can be controlled by diet, exercise and medication.Regular self monitoring of blood glucose levels should also be a major part in management of diabetes. The frequency and time of checking depends on different factors like type of diabetes, level of glycemic control, individual’s overall health.

American diabetes association encourages daily monitoring of blood glucose levels in diabetics. Daily monitoring can be done by blood glucose meters or continuous glucose monitors. HbA1c is another test which gives an overall sense of how blood sugar control is over 3 months.

Why is regular self blood glucose monitoring important?

  • Helps you to maintain your target range, avoiding highs and lows of blood glucose levels. This will in turn help you to avoid long term and serious complications caused by Hyperglycemia or Hypoglycemia. Complications of Hyperglycemia include kidney, eye, nerves and wound healing problems.
  • Self monitoring helps in understanding the condition better in newly diagnosed.
  • It helps to determine your medication and insulin dosage.
  • Encourages in making better choices of foods.

  • Let you know if you need to do a ketone test.
  • Helps in setting goals and getting motivated to reach them.

Regular self monitoring of glucose has shown significant decrease in the HbA1c (average blood glucose) levels in diabetics.

Researchers studied the relationship between Self monitoring blood glucose and HbA1c in type 1 and type 2 diabetic patients (who monitored 3 to 4 times a day).

Type 1 diabetics have shown a 1% reduction in HbA1c levels than those who monitored less frequently.

Type 2 patients have shown 0.6% reduction in HbA1c levels.

There are several reliable blood glucose monitors available in the market. Talk to your physician about how frequently you need to test and the best way to record the results.
