Diabetes mellitus is one of the most pressing health challenges of the 21st century. According to the International Diabetes Federation (IDF), more than 537 million adults worldwide are living with diabetes in 2021, and this number is projected to rise to 643 million by 2030 and 783 million by 2045. In India alone, the number of people with diabetes is estimated at over 77 million, making it the diabetes capital of the world. The chronic nature of diabetes, its silent onset, and its complications—ranging from cardiovascular disease, kidney failure, blindness, to amputations—highlight the need for a structured, comprehensive package of screening and monitoring. Unlike acute illnesses, diabetes requires lifelong surveillance, not only for glycemic control but also for prevention and early detection of complications. A well-designed diabetes screening and monitoring package ensures early diagnosis, risk stratification, timely intervention, and regular follow-up. It combines medical, technological, and lifestyle components into a holistic framework that improves patient outcomes, reduces healthcare costs, and enhances quality of life. Objectives of a Comprehensive Package A structured package for diabetes screening and monitoring should aim to: Detect undiagnosed diabetes and prediabetes in high-risk populations. Identify comorbidities like hypertension, dyslipidemia, and obesity. Monitor glycemic status and assess effectiveness of treatment. Detect early complications involving eyes, kidneys, nerves, and heart. Provide lifestyle modification support—nutrition, physical activity, stress management. Incorporate technological tools for real-time monitoring and adherence. Ensure cost-effectiveness and accessibility for urban and rural populations. Target Population for Screening Screening is essential because diabetes often remains undiagnosed until complications develop. The following groups should be prioritized: General adult population: All adults ≥35 years should undergo baseline screening. High-risk individuals (any age): Family history of diabetes (first-degree relative). Overweight/obesity (BMI ≥23 kg/m² in Asians). Sedentary lifestyle. Hypertension, dyslipidemia, or cardiovascular disease. History of gestational diabetes or delivering a baby >4 kg. Polycystic ovarian syndrome (PCOS). Children and adolescents: Overweight children with ≥2 risk factors (family history, ethnicity, maternal history, obesity-related comorbidities). Components of Screening 1. Risk Assessment Questionnaire-based tools such as the Indian Diabetes Risk Score (IDRS), FINDRISC, or ADA risk calculator. Parameters include age, BMI, waist circumference, physical activity, family history, and hypertension. 2. Clinical Examination Measurement of BMI, waist-to-hip ratio, and blood pressure. Signs of insulin resistance: acanthosis nigricans, skin tags, central obesity. 3. Laboratory Investigations Fasting Plasma Glucose (FPG): ≥126 mg/dL diagnostic. Oral Glucose Tolerance Test (OGTT): 2-hr plasma glucose ≥200 mg/dL diagnostic. HbA1c: ≥6.5% diagnostic; also useful for monitoring. Random Plasma Glucose: ≥200 mg/dL with classic symptoms. Diagnostic Criteria (ADA/WHO/ICMR Guidelines) Test Normal Prediabetes Diabetes FPG <100 mg/dL 100–125 mg/dL ≥126 mg/dL OGTT (2hr) <140 mg/dL 140–199 mg/dL ≥200 mg/dL HbA1c <5.7% 5.7–6.4% ≥6.5% Diagnosis should be confirmed with repeat testing unless unequivocal hyperglycemia is present. Monitoring Parameters Monitoring goes beyond just blood sugar checks. A comprehensive package should include: 1. Glycemic Monitoring Self-Monitoring of Blood Glucose (SMBG): Fasting, pre-meal, post-meal, bedtime. Continuous Glucose Monitoring (CGM): Provides trends, hypoglycemia detection, glucose variability. HbA1c (every 3–6 months): Long-term control marker. Target usually <7%. 2. Metabolic Monitoring Lipid profile (annually, more frequently if uncontrolled). Blood pressure monitoring (every visit). Weight, BMI, waist circumference (monthly). 3. Organ-Specific Monitoring Eyes: Fundus examination/retinal photography annually. Kidneys: Urine albumin-creatinine ratio, eGFR yearly. Nerves: Foot examination (monofilament, vibration sense) annually. Heart: ECG and cardiovascular risk assessment every 1–2 years. 4. Lifestyle & Psychosocial Monitoring Diet adherence and nutritional counseling. Physical activity tracking (pedometers, fitness apps). Stress, sleep, and mental health assessment. Technological Aids in Monitoring Continuous Glucose Monitors (CGM): Real-time insights, useful for insulin-dependent diabetics. Smartphone Applications: Diet logging, reminders, doctor-patient communication. Telemedicine: Remote consultations, especially for rural patients. Wearables: Track activity, sleep, and calorie expenditure. Frequency of Screening & Monitoring At-risk but non-diabetic individuals: Every 3 years. Prediabetes: Annually. Diabetes: HbA1c: Every 3–6 months. Lipid profile: Annually. Renal, eye, and nerve screening: Annually. Foot check: At every visit. Integration with Lifestyle, Diet, and Exercise Plans A comprehensive package must go beyond diagnosis to include preventive and therapeutic lifestyle changes: Nutrition: Personalized diet plans emphasizing low glycemic index foods, fiber, portion control, and reduced refined sugars. Exercise: At least 150 minutes of moderate aerobic activity per week + resistance training twice weekly. Behavioral Support: Counseling for stress management, smoking cessation, and alcohol moderation. Cost-Effectiveness & Accessibility Using risk scores and basic tests (FPG, HbA1c) for mass screening is cost-effective. Community-based programs, health camps, and integration into primary healthcare systems make screening more accessible. Insurance packages and government schemes (like Ayushman Bharat) can cover essential monitoring. Challenges in Implementation Awareness gap – Many remain undiagnosed until complications appear. Healthcare infrastructure – Rural areas lack diagnostic facilities. Cost of monitoring devices – CGM and insulin pumps are expensive. Patient adherence – Lifestyle changes are difficult to sustain. Fragmented care – Lack of integrated multidisciplinary teams.
