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
