Glucose is the central reference substance in the human blood sugar system. It is chemically identical to Dextrose, colloquially known as glucose. At Diabetes mellitus The regulation of glucose metabolism is impaired by a lack of insulin or a reduced insulin effect. As a result, the intake of dextrose has a directly measurable effect on the glucose level.
Pathophysiology: Diabetes and Glucose
Diabetes mellitus is characterized by a permanently elevated blood glucose concentration. The role of insulin is crucial for the transport of glucose into the body's cells:
- Typ-1-Diabetes: Decreased or absent insulin production.
- Type 2 diabetes: Decreased insulin action (insulin resistance) and relative insulin deficiency.
- Insulin function: Regulates the intake of Glucose from the blood into muscle and fat cells.
Dextrose as a reference substance
| aspect | Classification |
|---|---|
| Chemical identity | Corresponds to the measured blood glucose (C₆H₁₂O₆). |
| Absorption | Absorption via the small intestine without prior enzymatic cleavage. |
| Impact on glucose levels | Significant increase when taken orally. |
| Application context | Commonly mentioned in connection with hypoglycemia. |
Metabolic effects
- Direct absorption: Dextrose enters the bloodstream without prior breakdown.
- Regulation: If insulin action is impaired, control of glucose levels requires external control (e.g. drug therapy or Insulin).
- Monitoring: Blood glucose meters and CGM systems record the concentration of glucose in the blood or tissue.
Classification in the therapy context
- Physiological role: Glucose is an essential source of energy, especially for the central nervous system.
- Individual assessment: The assessment of glucose uptake depends on the type of therapy, physical activity and current metabolic status.
- Hypoglycemia: In the diabetological context, glucose is often mentioned when blood sugar levels are low.
Summary
Dextrose is chemically identical to the glucose measured in the blood and directly influences glucose levels. In the case of diabetes, their intake requires conscious consideration of the individual therapy and metabolic situation.
