Can high white blood cell count in newborns cause hypoglycemia?

Generally, elevated white blood cell count in newborns does not directly cause hypoglycemia. High white blood cell levels in newborns may result from infections, inflammation, or other diseases that trigger an immune system response. Specifically:

Infection is one of the common causes of increased white blood cell count in newborns. Infections can stimulate the immune system, leading to elevated white blood cell counts. Infections may also affect the newborn's energy metabolism, potentially causing hypoglycemia. Since a newborn's immune system is not yet fully developed, there is an inherent risk of immune system abnormalities. Certain immune-related disorders or dysfunctions may lead to elevated white blood cells and, in some cases, may also be associated with hypoglycemia. Additionally, other medical conditions or diseases—such as genetic metabolic disorders or endocrine disturbances—can cause both elevated white blood cell counts and hypoglycemia in newborns.

If a newborn exhibits any symptoms of discomfort, it is recommended to seek prompt medical attention at a hospital to avoid delays in diagnosis and treatment.
