Study Notes
Normal Range
- Normal fasting plasma glucose levels range from 3.9-5.6 mmol/L (70-100 mg/dl)
- CSF glucose levels are typically between 2.2 – 4.2 mmol/L (40-75 mg/dl) or approximately 60% of plasma value
Hyperglycemia
- Hyperglycemia is characterized by high levels of sugar (glucose) in the blood
- It occurs due to:
- Lack of insulin production in the body (type 1 diabetes)
- Insulin resistance, where the body does not respond effectively to insulin (type 2 diabetes)
- Insulin is a hormone that facilitates glucose absorption into cells for energy production
- Glucose intolerance is a broader term encompassing metabolic conditions that result in elevated blood glucose levels
This quiz covers normal range and hyperglycemia of blood glucose levels, including factors contributing to high sugar levels in the blood such as insulin resistance and type 1 and 2 diabetes.
