    Study Notes

    Diabetes

    • Diabetes is a chronic condition with high blood sugar levels.
    • Characterized by the body not producing enough insulin or not using insulin effectively.
    • Two main types: Type 1 and Type 2.

    Type 1 Diabetes

    • Autoimmune condition.
    • Body mistakenly attacks insulin-producing cells in the pancreas.
    • Usually diagnosed in children and young adults.
    • Requires insulin therapy to manage blood sugar.

    Type 2 Diabetes

    • More common.
    • Often associated with lifestyle factors.
    • Body becomes resistant to insulin or doesn't produce enough.
    • Typically develops in adults but increasingly seen in children.
    • Management includes lifestyle changes, medications, and sometimes insulin therapy.

    Mechanisms of Diabetes

    Type 1 Diabetes

    • Autoimmune Reaction: Immune system attacks and destroys insulin-producing beta cells in the pancreas.
    • Insulin Deficiency: Insulin production decreases dramatically due to beta cell destruction. High blood sugar levels result.

    Type 2 Diabetes

    • Insulin Resistance: Body cells become less responsive to insulin, hindering glucose uptake.
    • Impaired Insulin Secretion: Over time, the pancreas may not produce enough insulin to overcome the resistance.
    • Increased Gluconeogenesis: Liver produces excess glucose, further contributing to high blood sugar.

    Treatment for Diabetes

    Type 1 Diabetes

    • Insulin Therapy (injections or pump)
    • Monitoring Blood Sugar
    • Dietary Management (focus on carbohydrate counting)
    • Physical Activity (improves insulin sensitivity and overall health)

    Type 2 Diabetes

    • Lifestyle Changes (diet and exercise)
    • Oral Medications
