Study Notes
Glucose Tests
- Diabetes Mellitus is categorized into Type 1, Type 2, and Gestational Diabetes.
- Type 1 Diabetes is characterized by the absence of functional beta cells, leading to insufficient insulin production.
- Type 2 Diabetes involves impaired glucose tolerance, causing increased blood glucose due to insulin resistance.
- Monitoring blood sugar is crucial for diabetes management and includes testing before meals, after exercise, and during illness.
- Target blood glucose levels depend on various factors, including type of diabetes, age, disease severity, and overall health.
Diagnostic Criteria and Testing Types
- Fasting Plasma Glucose (FPG) is used for diagnosis; normal levels vary based on individual factors.
- Oral Glucose Tolerance Test (OGTT) assesses glucose metabolism over a period.
- Hemoglobin A1c indicates average blood sugar levels over the past three months.
- Insulin tests evaluate insulin production and sensitivity.
- D-Xylose Absorption Test assesses the intestines' ability to absorb simple sugars.
Gluconeogenesis
- Gluconeogenesis is primarily performed by the liver to convert non-carbohydrate sources into glucose.
- Key enzymes include malate dehydrogenase, which facilitates conversion from malate to oxaloacetate.
- Pyruvate can convert to phosphoenolpyruvate (PEP) through processes occurring in both the cytosol and mitochondria.
Pentose Phosphate Pathway (PPP)
- The PPP functions as an alternative metabolic route for glucose oxidation.
- It does not generate ATP but produces NADPH, essential for fatty acid and steroid synthesis, as well as antioxidant defenses.
- The pathway also synthesizes ribose for nucleotides and nucleic acids, highlighting its role in cell growth and replication.
Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency
- G6PD deficiency can lead to clinical symptoms related to oxidative stress, affecting red blood cell stability.
- Therapy focuses on avoiding triggers for hemolysis and may include dietary adjustments and, in some cases, medications to manage symptoms.
Implications for Clinical Practice
- Blood glucose testing frequency is tailored to the individual's diabetes type and treatment approach.
- Immediate intervention is necessary for managing hypo- or hyperglycemia based on test results and symptomatology.
