does viral infection increase blood sugar in non diabetics

Viral infections can result in elevated blood glucose levels in individuals without diabetes. This typically occurs as a stress response to the infection, which alters hormone levels and, in turn, impacts blood glucose levels.

Firstly, mild viral infections like the common cold may induce minor blood glucose fluctuations, but they generally do not cause significant hyperglycemia. Secondly, more severe infections such as influenza or hepatitis can lead to more pronounced increases in blood glucose, as these illnesses provoke a more intense stress response, releasing higher amounts of stress hormones like cortisol and adrenaline, which can elevate blood glucose levels to provide energy to fight the infection. Lastly, rare viral infections, such as Ebola or Zika, can trigger extreme stress responses, causing a marked increase in blood glucose levels.

For non-diabetic individuals who notice elevated blood glucose levels during a viral infection, it is important to closely monitor these changes and seek medical assistance when required. Physicians may recommend dietary adjustments, increased physical activity, or medication to manage blood glucose levels. In all cases, medication should be taken under a doctor's supervision and not self-administered without guidance.
