Why is a child's blood sugar level checked?

24.05.2022 0 By admin

The norm of blood sugar in children is determined using a special test. It should be carried out regularly in order to identify possible diseases at an early stage and start treatment on time. Low sugar levels can lead to severe disorders of the internal organs and the central nervous system. A high level of sugar in the blood may indicate the development of hyperglycemia.

What should be the norm of blood sugar in children

The level of sugar at each age is different. This is due to the physiological characteristics of the body. In infants, sugar levels are significantly lower than in adults. The indicators also differ in newborns and children of the preschool group.

blood sugar levels in children

The blood sugar level in children depends on the age of the child.

In infants, the sugar norm is from 2.78 to 4.4 mmol / l. Anything above the norm indicates the presence of an endocrinological pathology or that the analysis was taken after eating. In children under 2 years of age, the indicators are at the same level.

At the age of 2 years and in children of the preschool group, normal values are from 3.3 to 5 mmol / l. Starting from the age of 6, the norm increases and varies between 3.3-5.5 mmol / l, the same indicators are typical for adults.

What can high or low blood sugar indicate?

Low blood sugar is called “hypoglycemia”, blood glucose levels do not exceed 2.5 mmol / l. This condition can lead to severe disruption of the internal organs and the central nervous system, and therefore requires urgent medical attention. With extremely low glucose levels, a child can lose consciousness, fall into a hypoglycemic coma and die. To raise your glucose levels, give your child candy, sugar, or any carbohydrate food (pastries, potatoes, etc.)

There may be several reasons for this condition:

  • maternal diabetes;
  • endocrine disorders;
  • malnutrition with prolonged fasting;
  • stressful situations;
  • high physical activity;
  • diabetes in a child.

If during the examination a child has a high level of sugar in the blood, we can talk about the development of hyperglycemia. The sugar content in this case exceeds 6.1 mmol / l. This is the main sign of diabetes mellitus or impaired glucose tolerance (pre-diabetes).

Elevated levels may also indicate problems with the pancreas, or may be caused by increased physical activity. Diseases of the pituitary and thyroid glands are also accompanied by elevated blood sugar levels.

Symptoms of diabetes in a child

Children are more likely to develop type 1 diabetes mellitus – in 98% of cases, and only 1-2% have type 2 diabetes.

The first type suggests that the child’s body does not produce enough insulin. Previously transferred infectious diseases can serve as a provocateur of the disease: measles, chicken pox, rubella.

symptoms of diabetes

If your child has symptoms of diabetes, check their blood sugar levels

Signs of pathology:

  • Strong thirst. Babies drink a lot and at the same time behave restlessly and often cry. Older children can drink several liters of water per day.
  • Frequent urination. In newborns, diapers remain white.
  • Weight loss. The child quickly loses weight, loses appetite.
  • General malaise, weakness.
  • Increased appetite, with preference given to sweets.
  • Reduced vision.
  • Wounds and scratches take a long time to heal.
  • Increased excitability and irritability.
  • Fungal diseases.
  • General decline in immunity.

If a child has several symptoms at once, it is necessary to urgently seek medical help, as uncontrolled spikes in glucose levels can lead to coma and even death.

Additional types of diagnostics and preparation for it

A deviation from the norm during the study does not mean that the baby develops diabetes. To confirm the diagnosis, it is necessary to re-diagnose.

An error can be caused by a simple non-compliance with the rules of preparation: breakfast before donating blood, taking medications. Before testing, this must be abandoned.

If the baby’s indicators vary from 5.5 to 6.1 mmol / l, the doctor may additionally prescribe a special glucose tolerance test.

The analysis for glucose is carried out strictly on an empty stomach. In this case, the child should drink a glucose solution. Repeated testing after taking glucose is carried out after a few hours.

Preparation includes not exercising or being active, and not eating for several hours before the test.

If, after testing, the sugar level shows at least 7.7 mmol / l, then there is a high probability of developing diabetes. Additionally, a blood test for glycated hemoglobin can be done to clarify the severity of the condition.

The blood sugar level in children depends on age. If the indicators differ in different periods of time, this does not mean that the child develops a dangerous disease. Special tests will help determine the level of sugar, and additional diagnostics will reveal the presence or absence of health problems.
