Diabetic Living Questions And Answers By Dr. Ravi Shankar

  1. Should I check my blood sugar levels at home with a glucose monitor? How often should I check them?


Glucose monitors, usually called Glucometers are readily available in the market and are useful devices to monitor one’s blood glucose levels, in order to understand where one stands in terms of his or her glucose control. They facilitate achieving optimal glucose control, are user friendly and cost-effective.

They are invaluable tools for Type 1 Diabetics who are on Insulin treatment. Glucometers are also helpful in Type 2 Diabetics who are using Insulin and also are recommended sometimes in some Diabetics on Oral Diabetes medications.

Glucometers help readily recognize if a Diabetic is having low blood Glucose, fluctuations in blood glucose, very high blood glucose. They are not usually recommended for diagnosing Diabetes newly. Glucometers are reasonably accurate and check capillary blood glucose.

Whether one should buy a Glucometer and check at home depends on the type and severity of Diabetes, the stage of Diabetes, their  clinical needs, risk of low glucose, whether on oral medications or Insulin,  the type of oral medications used by the person and also affordability to a certain extent especially in the Indian context. The frequency of checking would also depend on these parameters and is advocated to take the advice of one’s doctor, so that one does not under use or over use Glucometer.


  1. What are my goals regarding blood sugar levels?


Goals of blood glucose can vary from person to person. It is essential to discuss this with one’s doctor so that optimal health outcomes are achieved by targeting the optimal blood glucose targets for that particular individual. The mantra is individualized and patient-centered approach.


For instance, if someone has long standing Diabetes for 40 years, old and frail and living alone, using Insulin, and at risk of low blood glucose; then that individual may be better with a less tight glucose control.


On the contrary, someone young and fit otherwise, at less risk of low blood glucose, needs to aim for a tight glucose control. Pregnant women with Diabetes or those Diabetics planning pregnancy ought to aim for a tight glucose control for the wellbeing of both mother and baby.


Fasting glucose targets may be between 70 to 140 mg/dl and random, post meal readings glucose targets can be between 70 to 200 mg/dl, depending on various clinical, and social factors. Specific individualized targets are essential from time to time for each individual Diabetic.


At the same time, it is of paramount importance to understand that HbA1c, also called Glycated Haemoglobin is the bench mark to judge one’s glucose control. This gives the last 2-3 month average of one’s blood glucose and is more accurate in predicting the future risk of one’s Diabetes-related complications. The usual target of HbA1c is around 7% in those with Diabetes, but again has to be individualized.


Suffice to say that blood glucose treatment goals have to be individualized, and it is pertinent to state in this context that other important goals relevant to Blood Pressure and Cholesterol control should not be ignored in those with Diabetes.
