Understanding Diabetes: Types, Symptoms & Everyday Management

India has 101 million people with diabetes — the world's largest diabetes population. Understand the types, warning signs, and practical daily management strategies.

India is now the "diabetes capital of the world" with over 101 million adults living with the condition (ICMR, 2023). Yet nearly half remain undiagnosed. Early detection and lifestyle changes can delay, prevent, or even reverse Type 2 diabetes.

Types of Diabetes

• Type 1 Diabetes — autoimmune; the pancreas produces little or no insulin. Requires lifelong insulin therapy. Usually diagnosed in childhood.
• Type 2 Diabetes — the body becomes resistant to insulin or doesn't produce enough. Accounts for 90–95% of all cases. Strongly linked to lifestyle.
• Gestational Diabetes — develops during pregnancy and usually resolves after delivery, but increases future T2D risk.
• Prediabetes — blood sugar is higher than normal but not yet at diabetic levels. Fully reversible with lifestyle changes.

Warning Signs of Diabetes

• Frequent urination, especially at night
• Excessive thirst and dry mouth
• Unexplained weight loss
• Blurred vision
• Slow-healing cuts and wounds
• Tingling or numbness in hands/feet
• Recurring skin, gum, or bladder infections
• Fatigue and irritability

Diagnostic Tests

• Fasting Blood Glucose: Normal <100 mg/dL; Prediabetes 100–125; Diabetes ≥126
• HbA1c (3-month average): Normal <5.7%; Prediabetes 5.7–6.4%; Diabetes ≥6.5%
• Post-Prandial (2hr after meal): Diabetes ≥200 mg/dL

Diet: The Foundation of Diabetes Management

Eat more:

• Non-starchy vegetables (leafy greens, brinjal, capsicum, bitter gourd)
• Whole grains (brown rice, jowar, bajra, ragi)
• Legumes and pulses — low glycaemic index
• Fish and lean protein
• Healthy fats: nuts, seeds, coconut, olive oil

Limit or avoid:

• White rice, maida (refined flour), white bread
• Sugary drinks, fruit juices
• Deep-fried snacks and sweets
• Processed and packaged foods high in salt and sugar

Exercise for Diabetes

Exercise improves insulin sensitivity, lowers blood sugar, and reduces cardiovascular risk. Aim for 150 minutes of moderate exercise per week — brisk walking is excellent. Resistance training (yoga, weights) 2–3 times per week improves glucose metabolism.

Monitoring and Medications

Check your blood sugar regularly as advised by your doctor. Keep a log of readings, meals, and activity. If prescribed medication or insulin, take it consistently. Never skip doses or self-adjust without medical advice.

Long-term Complications to Watch For

Uncontrolled diabetes damages:

• Eyes (diabetic retinopathy — leading cause of blindness)
• Kidneys (diabetic nephropathy)
• Nerves (diabetic neuropathy — tingling, numbness)
• Heart and blood vessels (3× higher heart disease risk)
• Feet (poor circulation and infection risk)
• Teeth and gums
