How are Glukose and Blutzucker related?

Glucose and blood sugar (Blutzucker) are directly related: Glucose is a simple sugar (monosaccharide) that serves as the primary energy source for cells. Blood sugar refers to the concentration of glucose circulating in the blood. In practice, the terms are used interchangeably – a blood sugar test measures glucose levels. The body tightly regulates blood glucose via hormones like insulin and glucagon. Persistent high fasting glucose indicates impaired glucose tolerance or diabetes. Genetic variants (e.g., rs10830963 in MTNR1B) can affect glucose regulation, as can diet and exercise. Measurements are given in mg/dL or mmol/L. For consumers: 'Glucose' is the chemical name; 'blood sugar' is the everyday term for the same value. This is established physiological knowledge, not speculative.
