Home Blood Sugar Monitoring in Children

Home blood sugar monitoring (HBGM) is a crucial aspect of managing diabetes in children. It allows parents and caregivers to track their child’s blood sugar levels at home, providing valuable information for making informed decisions about medication, diet, and lifestyle. Here is a comprehensive guide to HBGM in children:

What is Home Blood Sugar Monitoring?

HBGM involves using a blood glucose meter to measure the amount of sugar (glucose) in your child’s blood. Glucose is the main source of energy for the body’s cells, and managing its levels is essential for good health in people with diabetes.

Why is HBGM Important?

HBGM helps parents and caregivers:

  • Track blood sugar levels throughout the day, identifying patterns and trends
  • Adjust medication and insulin dosages appropriately
  • Monitor the effectiveness of diabetes treatments
  • Identify and prevent blood sugar highs and lows (hyperglycemia and hypoglycemia)
  • Make informed decisions about diet, exercise, and other aspects of diabetes management

When to Monitor Blood Sugar

The recommended frequency of HBGM varies depending on the type of diabetes your child has and their individual needs. However, it is generally advised to:

  • Check blood sugar before meals and snacks
  • Check blood sugar at bedtime, especially if your child uses long-acting insulin
  • Check blood sugar at other times as needed, such as before physical activity or when your child is sick

How to Monitor Blood Sugar at Home

Monitoring blood sugar at home requires a blood glucose meter, test strips, and lancing device. Follow these steps:

  1. Wash your hands thoroughly.
  2. Prepare the lancing device. Insert a new lancet into the lancing device.
  3. Choose a finger to prick. Alternate fingers to avoid pain and calluses.
  4. Prick the side of your child’s finger. Apply gentle pressure to get a small drop of blood.
  5. Place a drop of blood on the test strip. Follow the instructions provided with your blood glucose meter.
  6. Read the blood sugar level. The blood glucose meter will display the blood sugar reading in milligrams per deciliter (mg/dL).

Interpreting Blood Sugar Results

Blood sugar levels can vary throughout the day and are influenced by many factors, including food, exercise, and stress. The target blood sugar ranges for children with diabetes vary based on their age and individual circumstances.

  • For most children with type 1 diabetes, the target blood sugar range is 70-180 mg/dL.
  • For most children with type 2 diabetes, the target blood sugar range is 80-130 mg/dL.

If your child’s blood sugar levels are consistently above or below these ranges, consult your healthcare provider for guidance.

Hyperglycemia (High Blood Sugar)

Hyperglycemia occurs when blood sugar levels are too high. Symptoms include:

  • Frequent urination
  • Excessive thirst
  • Blurry vision
  • Fatigue
  • Headaches

If your child experiences symptoms of hyperglycemia, check their blood sugar immediately. If the reading is over 250 mg/dL, give them insulin as directed by your healthcare provider.

Hypoglycemia (Low Blood Sugar)

Hypoglycemia occurs when blood sugar levels are too low. Symptoms include:

  • Shakiness
  • Sweating
  • Hunger
  • Irritability
  • Confusion
  • Seizures

If your child experiences symptoms of hypoglycemia, give them a quick-acting source of sugar, such as fruit juice, glucose tablets, or a sugary drink. Then, check their blood sugar level and seek medical attention if necessary.

Troubleshooting HBGM

If you encounter any problems with HBGM, consider the following troubleshooting tips:

  • Check that the blood glucose meter is calibrated and the test strips are not expired.
  • Ensure that you are using the correct technique for pricking your child’s finger.
  • Clean the blood glucose meter regularly as per the manufacturer’s instructions.
  • Store the blood glucose meter and test strips in a cool, dry place.
  • Avoid exposing the blood glucose meter to extreme temperatures or direct sunlight.


Home blood sugar monitoring is an essential tool for managing diabetes in children. By tracking blood sugar levels, parents and caregivers can identify patterns, adjust treatments, and prevent complications. Regular HBGM empowers children and their families to take an active role in their health and live well with diabetes.
