Children grow at a rapid rate, and for the normal functioning of their brain and organs, their bodies require an optimal amount of glucose. Diagnosing type 1 diabetes in kids is difficult due to lack of knowledge about the symptoms of glucose imbalance. In childhood, it is difficult at times to recognise the indications of low blood sugar (hypoglycaemia). Every child has different needs; ask your doctor to determine the best glucose levels for your child. Ensure that your child follows a healthy lifestyle and a proper diet for complete health and wellbeing. Lowered blood sugar levels can lead to several health problems in kids, and it is essential to check what’s normal for your kid: 

Right Blood Sugar Range

The blood sugar levels of healthy children lie between 70 and 150 mg/dL. It is normal if your child’s blood sugar fluctuates in this range. Blood sugar is typically higher after having a meal and lower after an intense physical workout. To help keep your child’s blood sugar in the normal range, ensure that you are giving him a healthy diet full of fresh fruits and vegetables.

Normal blood sugar level according to age groups

0-5 years

Normal blood sugar range in babies from newborns to five-year-olds is 100 to 200mg/dL. Fasting blood sugars should be near 100 mg/dL. Blood sugars after having meals and before going to bed should be somewhat close to 200mg/dl. If it is found below 150mg/dL before bedtime, it must be reported to your child’s health care provider. He may recommend a bedtime snack or testing before going to bed.

5-11 years

For children who are aged between 5-11, normal blood glucose levels are 70 to 150mg/dL. Fasting blood sugars must be close to the lower end of normal sugar level. Blood sugar after meals and before bedtime should be close to the upper end.  Glucose level below 120mg/dL during night calls for medical attention.

Age 12 and above

For children who are 12 or above, healthy blood sugar levels are similar to those of adults. Your doctor will recommend a bedtime snack if your child’s blood glucose level is lower than 100 mg/dl before going to sleep.

Preventing Hypoglycemia in Children

Diagnosing hypoglycaemia at the earliest stages is ideal for the treatment of your child. This can also aid in preventing it from becoming severe. Educate yourself and your child about the symptoms of hypoglycaemia. Teaching your child the ways to check blood sugar would be an added advantage. Inform the people around your child, such as schoolteachers, baby sitters, grandparents, uncle and aunts, close friends or coach about your child’s condition and the symptoms of hypoglycaemia, so that they can handle your child in your absence. Keep a tab on what your child eats throughout the day. Try to inculcate healthy eating habits and engage her in some physical activity.
