Glucosuria of Newborns

Neonatal glucosuria is a condition in which excess glucose is excreted in the urine in newborn babies. This occurs due to the immaturity of the kidneys and their inability to reabsorb all the glucose back into the blood.

Causes of glucosuria in newborns:

1. Kidney immaturity - the kidneys of newborns cannot completely reabsorb glucose from primary urine. This leads to loss of glucose in the urine.

2. Elevated blood glucose levels - excess glucose enters the kidneys and exceeds the reabsorption threshold, resulting in glucose being excreted in the urine.

3. Stress during childbirth - the release of catecholamines and glucocorticoids leads to an increase in blood glucose levels.

4. Disorders of carbohydrate metabolism in the mother - with diabetes in pregnancy, glucose freely passes through the placenta to the fetus.

Diagnosis of glycosuria is based on the detection of glucose in the urine. Treatment is aimed at maintaining normal blood glucose levels in the newborn. The prognosis is favorable, glucosuria disappears as the kidneys mature.
