Blood glucose
Blood glucose is one of the most important indicators of metabolic health, reflecting how effectively the body uses carbohydrates to produce energy. Even mild abnormalities may remain unnoticed for a long time while gradually increasing the risk of diabetes, cardiovascular disease, and other complications. A blood glucose test is a simple and reliable way to detect disorders of glucose metabolism at an early stage, assess your current metabolic status, and monitor the effectiveness of treatment in people living with diabetes.
What blood glucose level is considered normal?
In a healthy adult, a normal fasting blood glucose level is generally 3.9–5.5 mmol/L. Results above the normal range do not necessarily indicate diabetes, but they may suggest prediabetes, insulin resistance, or other metabolic disorders that require further evaluation.
It is important to remember that a blood glucose result should not be interpreted in isolation. Your doctor will consider your symptoms, lifestyle, family history, and the results of other laboratory tests. This comprehensive assessment helps detect abnormalities at an early stage and determine the most appropriate strategy for treatment.
Why can blood glucose levels be too high or too low?
Changes in blood glucose levels may be temporary or may indicate an underlying disorder of glucose metabolism. Blood glucose is influenced by lifestyle, diet, physical activity, and even certain medications. That is why doctors always look for the underlying cause of an abnormal result rather than relying on a single blood glucose measurement.
Important: a blood glucose test reflects your body's glucose level at the time the blood sample is collected. If it is necessary to evaluate how glucose levels change throughout the day or over several months, your doctor may recommend Continuous Glucose Monitoring (CGM).
The most common causes of changes in glucose levels:
- Type 1 or Type 2 diabetes
- Prediabetes and insulin resistance
- Excessive consumption of simple carbohydrates
- Long intervals between meals or fasting
- Intense physical activity
- Acute infectious diseases
- Chronic stress and lack of sleep
- Hormonal disorders
- Pancreatic diseases
- Use of certain medications
- Pregnancy and gestational diabetes
- Liver and kidney diseases
