Blood sugar levels serve as one amongst the indicators of a person’s health, especially for people who are at risk of diabetes and also for the ones with diabetes. To monitor our health, it is important to understand the blood sugar (glucose) levels, how they fluctuate and how food, activities, stress, etc, influence them. Let’s deep dive into what blood sugar target ranges are, why they matter, and how they differ depending on various factors.What is blood sugar?Blood sugar refers to the concentration of glucose present in the human bloodstream. Glucose is a simple sugar (monosaccharide) that is the body's primary source of energy. It is when an individual consumes food which consists of carbohydrates, glucose enters the bloodstream. Blood sugar is measured in levels, through which doctors can tell whether it is high, low or normal. Insulin, a hormone produced by the pancreas, helps cells intake glucose from the blood. Blood sugar target rangesBlood sugar targets can vary based on age, health status, type of diabetes, pregnancy, and other individual considerations. The ranges are as follows-1. Nonpregnant Adults with DiabetesGlycemic MetricTarget RangeA1C<7.0% (<53 mmol/mol)Preprandial (before meal) glucose80–130mg/dL (4.4–7.2mmol/L)Peak postprandial (after meal) glucose<180mg/dL (<10.0mmol/L)Time in Range (CGM, 70–180mg/dL)>70% of readingsTime Below 70mg/dL<4% of readingsTime Below 54mg/dL<1% of readings2. Children and AdolescentsGlycemic MetricStandard TargetCommentsA1C<7% (<53 mmol/mol)Most children and adolescentsA1C Less Stringent<7.5% or <8%If risk of hypoglycemia, limited resources, or other clinical contextsA1C More Stringent<6.5%Select individuals, if attainable without hypoglycemia or undue care burdenCGM Time in Range>70% (70–180mg/dL)Use CGM data whenever available3. Pregnancy (Including Type 1, Type 2 & Gestational Diabetes)Glycemic MetricTargetFasting glucose<95mg/dL (<5.3 mmol/L)1-hour postprandial<140mg/dL (<7.8 mmol/L)2-hour postprandial<120mg/dL (<6.7 mmol/L)A1C<6% (<42 mmol/mol) if without hypoglycemia; <7% (<53 mmol/mol) if necessarySensor TIR (CGM, 63–140mg/dL)>70% of readings (Type 1 recommended)Sensor Time <63mg/dL<4%Sensor Time <54mg/dL<1%Sensor Time >140mg/dL<25%Reference - The tables have been taken from the ADA guidelines 4. Older AdultsGenerally healthy: Standard adult targets may be used (A1C Step 1: Wash and clean your handsStep 2: Prepare the lancing deviceStep 3: Insert the test strip into the glucometerStep 4: Prick your finger carefully by using the lancing deviceStep 5: Apply blood to the stripStep 6: After obtaining the blood sample via finger prick, gently apply a sterile cotton ball or gauze to the puncture site to stop the bleeding through slight pressure. Record the result of the test immediately to ensure accuracy and traceability of the data collected. (WHO)Step 7: Dispose of the materials like used strip, cotton, used lancet etc. safely2. Continuous Glucose Monitors (CGMs): Provide real-time readings throughout the day. This is helpful for Type 1 diabetics or those with fluctuating levels.3. HbA1c test: This test measures average blood sugar over 2-3 months.Blood sugar target ranges should be considered when monitoring an individual's overall health. Careful monitoring and judicious maintenance of blood sugar target ranges are essential for managing diabetes and supporting long-term health. Whether someone is living with diabetes, at risk, or just health-conscious, monitoring their glucose levels and striving to stay within the optimal range is a wise step toward a healthier life. Always consult a healthcare professional to set personalised targets and build an effective management plan.References - https://diabetesjournals.org/care/issue/48/Supplement_1https://www.ncbi.nlm.nih.gov/books/NBK545196/ https://professional.diabetes.org/standards-of-care Seshiah, V., et al.
