    Study Notes

    Type 1 Diabetes

    • Represents approximately 5% of all diabetes cases.
    • Previously known as juvenile-onset diabetes or insulin-dependent diabetes mellitus (IDDM).
    • Develops primarily in childhood and adolescence; onset can be abrupt but may occur in adults.
    • Characterized by destruction of pancreatic β cells, leading to insufficient insulin production.
    • Autoimmune process targets β cells, with triggers likely involving genetic, environmental, and infectious factors.

    Type 2 Diabetes

    • Most prevalent form, accounting for 90% to 95% of diabetes cases.
    • Formerly known as non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes.
    • Typically begins in middle age and progresses gradually; carries low risk for ketoacidosis.
    • Symptoms arise from insulin resistance combined with impaired insulin secretion.
    • Patients can synthesize insulin, but its release is delayed and less effective.
    • Causes of insulin resistance include binding issues, reduced receptor numbers, and insensitivity.
    • Family history is a strong risk factor; genetic associations, such as with the IRS-2 gene, have been noted.

    Diabetes and Pregnancy

    • Managing diabetes during pregnancy remains complex despite improved insulin therapies.
    • Increased insulin needs due to placental hormones and higher cortisol levels promoting hyperglycemia.
    • Maternal hyperglycemia leads to excessive fetal insulin production, risking hyperinsulinism complications.
    • Maintaining glucose levels in both mother and fetus is crucial; poor control can be teratogenic.
    • Gestational diabetes can resolve postpartum; if it persists, reevaluation for chronic diabetes is necessary.
    • Oral diabetes medications are typically discontinued during pregnancy, except for metformin.

    Diagnosis of Diabetes

    • Diagnosis no longer relies solely on glucose levels; hemoglobin A1c (A1c) testing is now standard.
    • Diabetes is indicated by excessive plasma glucose levels and requires confirmation from two tests on different days.
    • Fasting plasma glucose (FPG) test identifies diabetes if levels are 126 mg/dL or higher after fasting for 8 hours.
    • Random plasma glucose test suggests diabetes if levels are 200 mg/dL or greater alongside classic symptoms.
    • Oral glucose tolerance test (OGTT) recognizes diabetes if 2-hour plasma levels are 200 mg/dL or above.

    Hemoglobin A1c Testing

    • A1c measures average blood glucose levels over 2 to 3 months.
    • A value of 6.5% or higher indicates diabetes but may be affected by conditions like pregnancy or anemia.

    Increased Risk for Diabetes (Prediabetes)

    • Defined by impaired fasting glucose (100-125 mg/dL) or glucose tolerance (OGTT result of 140-199 mg/dL).
    • Prediabetes is not synonymous with diabetes but signifies increased risk for type 2 diabetes and cardiovascular disease.
    • Risk factors for progression to diabetes may be mitigated through lifestyle changes and medications such as metformin.

    Overview of Treatment

    • The primary treatment goal is to prevent long-term complications by maintaining glucose levels close to normal.
    • Both type 1 and type 2 diabetes management includes proper diet, physical activity, and BP/lipid control.

    Management of Type 1 Diabetes

    • Complications are prevented through a comprehensive plan focusing on glycemic control and cardiovascular risk.
    • Insulin replacement is essential; careful alignment with carbohydrate intake is necessary to avoid hypoglycemia or hyperglycemia.
    • The role of additional medications as adjuncts to insulin is being explored.
    • Managing hypertension and dyslipidemia includes using ACE inhibitors or ARBs to lower nephropathy risk, aiming for a BP of ≤140/90 mm Hg.
