What can cause hyperglycemia?

Published in Hyperglycemia Causes 2 mins read

Hyperglycemia, or high blood sugar, occurs when there is too much glucose in the blood. Various factors, ranging from lifestyle choices to medication management, can contribute to its development.

The primary causes of hyperglycemia include:

  • Stress
  • Illness, such as a common cold
  • Eating too much, for instance, snacking between meals
  • Lack of exercise
  • Dehydration
  • Missing a dose of diabetes medication, or taking an incorrect dose
  • Over-treating an episode of hypoglycemia (low blood sugar)

Common Causes of High Blood Sugar

Understanding the triggers for hyperglycemia is crucial for effective management, especially for individuals with diabetes. These causes can often be categorized to better illustrate their impact.

Lifestyle and Dietary Factors

Daily habits play a significant role in blood sugar levels.
  • Eating Habits: Consuming excessive amounts of food, particularly high-carbohydrate or sugary snacks between meals, can lead to a rapid increase in blood glucose.
  • Physical Activity: A lack of regular exercise reduces the body's ability to use glucose for energy, causing it to build up in the bloodstream.
  • Hydration: Dehydration can concentrate blood glucose levels, making them appear higher.

Health-Related Influences

The body's response to various health conditions and emotional states can also elevate blood sugar.
  • Stress: Emotional or physical stress triggers the release of hormones that can increase blood glucose.
  • Illness: When the body is fighting an infection or illness, such as a cold, it releases stress hormones that can raise blood sugar levels as part of the immune response.

Medication and Treatment Management

For individuals on diabetes medication, adherence and correct dosage are vital.
  • Medication Errors: Forgetting to take a prescribed dose of diabetes medication or taking an incorrect dosage can directly lead to elevated blood sugar levels.
  • Over-treatment of Hypoglycemia: In an effort to correct low blood sugar (hypoglycemia), individuals might consume too much sugar, leading to a rebound effect where blood glucose spikes too high.
