Study Notes
Glucose Tests
- Diabetes Mellitus includes Type 1, Type 2, and Gestational forms.
- Type 1 Diabetes Mellitus is an autoimmune disorder leading to insulin production cessation.
- Type 2 Diabetes Mellitus features insulin resistance and glucose accumulation in the blood.
- Common symptoms of diabetes include polyuria, polydipsia, and polyphagia (3 P's).
Types of Blood Glucose Testing
- Plasma Glucose Levels: Measures glucose in blood; essential for diabetes diagnosis.
- Oral Glucose Tolerance Test: Assesses body's response to glucose over time.
- Hemoglobin A1c: Reflects average blood glucose levels over the past 2-3 months.
- Insulin Test: Evaluates insulin production and secretion abilities.
- D-Xylose Absorption Test: Assesses the ability to absorb simple sugars.
Testing Frequency
- Type 1 diabetes may require testing 4 to 10 times daily.
- Test before meals, snacks, and exercise; before bed; periodically at night.
- Type 2 diabetes patients on insulin should test before meals; others may not need daily testing.
Target Blood Glucose Levels
- Target blood sugar levels are individualized based on disease severity, age, duration of diabetes, pregnancy status, complications, and overall health.
Gluconeogenesis
- Converts non-carbohydrate substrates into glucose, critical during fasting or low-carbohydrate intake.
- Enzymatic reactions facilitate conversion from pyruvate and intermediates back to glucose.
Pentose Phosphate Pathway (PPP)
- Interplay between glucose metabolism and the PPP contributes to cellular functions including nucleotide synthesis and oxidative stress responses.
Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency
- G6PD plays a critical role in the pentose phosphate pathway and redox balance.
- Clinical presentation includes hemolytic anemia upon triggering factors (infections, certain medications).
- Treatment focuses on avoiding triggers and managing symptoms.
