What causes blood sugar to rise in non-diabetics?

If you have been thinking about what causes blood sugar to rise in non-diabetics, various factors contribute to the rise in blood sugar levels in non-diabetics:

  • Polycystic ovarian syndrome: This condition causes hormonal imbalances in women of reproductive age.
  • Stress: Unmanaged stress causes an increase in hormones such as cortisol and adrenaline that raise blood sugar levels.
  • poor diet: Consumption of foods with high carbohydrate content like white rice, pasta, fried foods, or processed foods.
  • Illness or injury: Stress due to injury or surgery can lead to high blood sugar levels in non-diabetic people.
  • Dehydration: Less water in the body could lead to concentrated blood sugar levels.
  • Infections: Any infection can cause a rise in blood sugar levels
  • Obesity: Fat cells in excess make your body resistant to insulin.
  • Medication: Certain medications, immunosuppressants, and corticosteroids may activate enzymes in your blood that can cause a rise in your blood sugar levels. Your body cannot get sufficient energy from sugars in your blood, and you might feel tired all day.
  • Insufficient sleep: Not getting enough sleep can make your body utilise less insulin.
  • Family history: Your genetic makeup can make you susceptible to spikes in sugar levels, though you do not have diabetes. Non-diabetic people with a family history of diabetes are more likely to experience high blood sugar levels.
  • Lifestyle: Physical inactivity can lead to high blood sugar levels in non-diabetics.
  • Cushing’s syndrome: It is a disorder of the endocrine system when the body produces too much cortisol. Cortisol is a hormone that can cause insulin resistance. As a result, blood sugar levels are elevated in non-diabetic people.
