What is Hyperglycemia?

Hyperglycemia, or high blood sugar, occurs when there is too much glucose in the blood. It is commonly associated with diabetes and can result from several factors.


What Causes Hyperglycemia?

  • Diabetes: Diabetes Types 1 and 2 are the primary causes. Insufficient insulin production or the body’s ability to use insulin reduces, effectively leading to high blood sugar levels.
  • Diet: Consuming too many carbohydrates or sugary foods can cause a spike in blood sugar.
  • Lack of Exercise: Physical activity helps the human body use glucose; inactivity can lead to elevated levels.
  • Stress: The blood sugar increases by both physical and emotional stress.
  • Medications: Certain medications, like corticosteroids, can raise blood sugar levels.
  • Illness: Infections or illnesses can cause temporary spikes in blood sugar levels.
