Understanding Type 1 Diabetes

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.
