Diabetes

Symptoms of Diabetes:
Diabetes often manifests through several common symptoms due to high blood sugar levels affecting the body's metabolism:

• Polyuria: Excessive urination as the kidneys filter out extra glucose.
• Polydipsia: Increased thirst caused by fluid loss through urine.
• Polyphagia: Increased hunger because cells are not receiving enough glucose for energy.
• Unexplained weight loss: Despite normal or increased appetite, weight loss occurs due to the body breaking down fat and muscle.
• Fatigue: Lack of energy due to inefficient glucose utilization.
• Blurred vision: High glucose levels affect the lens of the eye.
• Slow healing of wounds and frequent infections: Due to impaired immune function.

Laboratory Investigations for Diagnosis:
Diagnosis of diabetes is confirmed through blood tests that measure glucose levels under different conditions:

• Fasting Blood Sugar (FBS): Measures blood glucose after an overnight fast (8-12 hours). A value of on two separate occasions indicates diabetes.
• Postprandial Blood Sugar (PPBS): Blood glucose measured 2 hours after eating. A level of indicates diabetes.
• Random Blood Sugar (RBS): Blood glucose measured at any time, with symptoms present, a level of suggests diabetes.
• Glycated Hemoglobin (HbA1c): Reflects average blood glucose over the past 2-3 months. A value confirms diabetes.
• Oral Glucose Tolerance Test (OGTT): Measures blood glucose before and 2 hours after drinking a glucose solution (75g). A 2-hour blood glucose level confirms diabetes.

Diabetes mellitus is a chronic metabolic disorder characterized by elevated blood glucose levels (hyperglycemia) resulting from defects in insulin secretion, insulin action, or both. Insulin is a hormone produced by the pancreas that helps regulate blood sugar by facilitating the uptake of glucose into the cells for energy production. There are mainly two types of diabetes:

• Type 1 Diabetes: An autoimmune condition where the body’s immune system destroys insulin-producing cells in the pancreas, leading to little or no insulin production.
• Type 2 Diabetes: A condition where the body becomes resistant to insulin or does not produce enough insulin to maintain normal glucose levels.

If left uncontrolled, diabetes can lead to serious complications affecting the heart, kidneys, eyes, and nerves.

Diabetic Education is a structured process that helps individuals with diabetes understand their condition and effectively manage it. It includes:

• Nutritional Guidance: Learning about a balanced diabetic diet and carbohydrate control.
• Monitoring: Teaching how to check blood glucose levels regularly.
• Medication Awareness: Understanding insulin or oral hypoglycemic drugs.
• Lifestyle Tips: Emphasizing physical activity, foot care, and stress management.
• Preventing Complications: Encouraging routine screenings and awareness about symptoms.
