What is the recommended treatment approach for an adult patient of Indian descent with diabetes, according to the Indian guideline for diabetes management?

Indian Diabetes Management Guidelines

Initial Pharmacologic Approach

All adults with newly diagnosed type 2 diabetes in India should start metformin immediately alongside lifestyle modifications unless contraindicated, as this combination reduces all-cause mortality by 29.5% and cardiovascular events by 30-35%. 1

• Metformin is overwhelmingly the first-line drug of choice, with 94-95% of Indian physicians choosing it for patients with diabetes and abdominal obesity 2
• This aligns with both American Diabetes Association and Indian practice patterns 2
• For non-obese patients, opinions are divided: 31% of Indian physicians follow ADA guidelines (metformin first), while 66% follow Association of Physicians of India/Indian College of Physicians guidelines (glimepiride first) 2

Glycemic Targets

• Target HbA1c of 7% (53 mmol/mol) or less for most nonpregnant adults with life expectancy >10 years to prevent microvascular complications 1
• The American College of Physicians recommends HbA1c between 7-8% for most adults 1
• Only 36.3% of Indians with diabetes achieve good glycemic control (HbA1c <7%), highlighting the treatment gap 3

Second-Line Therapy Escalation

When HbA1c remains above target after 3 months on metformin plus lifestyle modifications, add either an SGLT-2 inhibitor or GLP-1 receptor agonist, as this combination reduces mortality and morbidity more effectively than other options. 1

• For postprandial hyperglycemia specifically, 74% of Indian physicians choose the combination of metformin and sulfonylurea 2
• This reflects the marked postprandial glycemia characteristic of Asian Indians 4

Comprehensive ABC Target Achievement

Only 7.7% of Indians with self-reported diabetes achieve all three ABC targets (HbA1c <7%, blood pressure <140/90 mmHg, LDL cholesterol <100 mg/dL), representing a critical care gap. 3

Individual target achievement rates:

• Good glycemic control (HbA1c <7%): 36.3% 3
• Blood pressure control (<140/90 mmHg): 48.8% 3
• LDL cholesterol control (<100 mg/dL): 41.5% 3

Cardiovascular Risk Management

• Initiate ACE inhibitor or ARB as first-line antihypertensive agent due to proven cardiovascular benefit in diabetes 5
• Target blood pressure <140/90 mmHg with lifestyle therapy plus pharmacologic treatment 5
• Initiate statin therapy in most patients with diabetes ≥40 years for cardiovascular protection 5
• 86% of Indian physicians correctly identify that hydrochlorothiazide worsens uric acid levels in diabetics with hypertension 2

Lifestyle Modifications

Refer all patients to a registered dietitian at diagnosis for individualized medical nutrition therapy. 1

Physical Activity Requirements

• Adults should engage in at least 150 minutes per week of moderate-intensity aerobic activity, spread over at least 3 days with no more than 2 consecutive days without activity 6
• Alternative: minimum 75 minutes/week of vigorous-intensity or interval training for younger and more physically fit individuals 6
• Resistance exercise 2-3 sessions/week on nonconsecutive days 6
• Interrupt prolonged sitting every 30 minutes for blood glucose benefits 6

Nutritional Recommendations

• Limit sodium consumption to <2,300 mg/day 6
• Limit saturated and trans fatty acids to <7% of energy intake 6
• Limit cholesterol intake to <200 mg/day 6
• Consider adding plant stanols/sterols (2 g/day) to lower LDL cholesterol by 8-29 mg/dL 6
• Increase soluble fiber intake (10-25 g/day) to decrease LDL cholesterol by approximately 2.2 mg/dL per gram 6

Alcohol Recommendations

• Limit alcohol to ≤1 drink/day for women or ≤2 drinks/day for men 5
• Take extra precautions to prevent hypoglycemia when consuming alcohol 6

India-Specific Considerations

83% of Indian physicians are aware that Indians have a genetic predisposition to diabetes due to inherently smaller beta cell mass associated with insulin resistance. 2

Key population-specific factors requiring algorithm adaptation:

• Early age of onset of diabetes 4
• Occurrence in nonobese and lean individuals 4
• Marked postprandial glycemia 4
• High-carbohydrate dietary practices 4
• Frequent infections including tuberculosis 4
• Low access to healthcare and medications in lower socioeconomic strata 4

Hypoglycemia Management

• Treat hypoglycemia with 15-20g rapid-acting glucose (glucose tablets, fruit juice, sports drinks, regular soda, hard candy) 6, 1
• If self-monitoring shows continued hypoglycemia after 15-20 minutes, repeat treatment 6
• Once blood glucose returns to normal, consume a meal or snack to prevent recurrence 6
• Prescribe glucagon for all individuals at significant risk of severe hypoglycemia 6, 1
• Educate patients on hypoglycemia risk with alcohol 5, 1

Glucose Monitoring Strategy

• Self-monitoring of blood glucose may be unnecessary in patients on metformin combined with SGLT-2 inhibitor or GLP-1 agonist (no hypoglycemia risk) 1
• Only 16.7% of Indians with diabetes and 36.9% of those on insulin report using self-monitoring of blood glucose, representing a major care gap 3
• For patients on insulin or insulin secretagogues, carbohydrate counting or meal planning approaches are essential to match insulin to carbohydrate intake 6

Screening and Monitoring

• Perform annual test to quantitate urine albumin excretion in type 1 diabetic patients with diabetes duration ≥5 years and in all type 2 diabetic patients starting at diagnosis 6
• Measure fasting lipid profile at least annually 6
• In adults with low-risk lipid values (LDL <100 mg/dL, HDL >50 mg/dL, triglycerides <150 mg/dL), lipid assessments may be repeated every 2 years 6
• Consider periodic testing of vitamin B12 levels in patients taking metformin, particularly those with anemia 6

Team-Based Care Structure

Utilize collaborative integrated team including physicians, nurse practitioners, physician assistants, Certified Diabetes Care and Education Specialists (CDCES), registered dietitian nutritionist, pharmacists, and behavioral health specialists or social workers. 1

• Provide diabetes self-management education (DSME) at diagnosis and as needed thereafter 6
• DSME should address psychosocial issues, as emotional well-being is associated with positive diabetes outcomes 6
• Screen for psychosocial problems such as depression, diabetes-related distress, anxiety, eating disorders, and cognitive impairment when self-management is poor 6

Critical Pitfalls in Indian Healthcare System

Public health facilities in India have major gaps: patient clinical records are not maintained at facilities (patients must keep their own records), HbA1c estimation is unavailable at primary health centers, and antidiabetic drugs are typically given for only 14 days. 7

• HbA1c estimation, lipid examination, and foot care are unavailable at primary health centers 7
• Insulin and statins are available only at secondary and tertiary care centers 7
• No formal referral or follow-up mechanism exists to link patients to decentralized facilities 7
• Higher education, male sex, rural residence, and shorter duration of diabetes (<10 years) are associated with better achievement of combined ABC targets 3
