Full Definition:
Blood glucose is the measurement of blood glucose levels, expressed in mg/dL (milligrams per deciliter) or mmol/L (millimoles per liter).
Glucose is the main source of energy for the body's cells, and maintaining optimal blood glucose levels is essential for proper organ function.
The body regulates blood sugar with the help of two main hormones:
- Insulinblood sugar, which lowers blood sugar, facilitating the penetration of glucose into cells;
- Glucagon, which increases blood sugar by stimulating the release of glucose from the liver.
Benchmarks (unsold):
- Normaal: 70—99 mg/dL
- Pre-diabetes: 100-125 mg/dL
- diabetes: ≥126 mg/dL(confirmed in at least two separate tests)
Blood sugar during intermittent fasting:
During fasting, blood sugar levels gradually decrease, which can be beneficial for:
- Decrease Insulinand insulin resistance,
- fat burning,
- reduction of inflammation and metabolic risk.
Usual Testing:
- Glucemia a binge (in the morning, on unsold)
- Glycemic curve (with or without insulin)
- Glycated haemoglobin (HbA1c) — reflects the average blood glucose of the last 2—3 months
Frequent imbalances:
- Hyperglycaemia: increased blood sugar — associated with diabetes, chronic inflammation, stress.
- Hypoglycaemia: low blood sugar — can occur with prolonged fasting, unbalanced diet, alcohol consumption or medication.
Symptoms of unstable blood sugar:
- sudden fatigue,
- dizziness,
- tremors,
- cold sweat,
- Exaggerated craving for sweet.
