Blood sugar levels are a crucial indicator of your overall health, and understanding what different readings mean can be complex. In this article, we will explore the different types of blood sugar readings, their meanings, and how to interpret them.

Understanding Blood Sugar Levels

Blood sugar levels are measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Normal blood sugar levels are typically between 70-99 mg/dL (3.9-5.5 mmol/L) after a meal and less than 140 mg/dL (7.7 mmol/L) two hours after a meal.

A fasting blood sugar test is done after an overnight fast of at least 8 hours. The test measures your blood sugar level before you eat or drink anything.

  • Normal: Less than 100 mg/dL (5.5 mmol/L)
  • Prediabetes: 100-125 mg/dL (5.5-6.9 mmol/L)
  • Diabetes: 126 mg/dL or higher (7 mmol/L or higher)

Hemoglobin A1C (HbA1C)

HbA1C is a test that measures your average blood sugar level over the past 2-3 months. It's a measure of your blood sugar control over time.

  • Normal: Less than 5.7%
  • Prediabetes: 5.7-6.4%
  • Diabetes: 6.5% or higher

Causes of High Blood Sugar

High blood sugar can be caused by a variety of factors, including:

  • Diet: Consuming high amounts of sugar, refined carbohydrates, and saturated fats can lead to high blood sugar.
  • Lack of exercise: Regular physical activity can help improve insulin sensitivity and lower blood sugar levels.
  • Stress: High levels of stress can cause your body to produce more cortisol, a hormone that can raise blood sugar levels.
  • Sleep deprivation: Not getting enough sleep can disrupt your body's natural insulin regulation.
  • Certain medications: Some medications, such as steroids and certain antidepressants, can raise blood sugar levels.
  • Medical conditions: Certain medical conditions, such as polycystic ovary syndrome (PCOS) and Cushing's syndrome, can cause high blood sugar.
