Diabetes in India: Prevention, Daily Management, Diet, Exercise and Monitoring Basics

India has one of the largest numbers of people with diabetes in the world, and many more with prediabetes who do not know it. South Asians tend to develop type 2 diabetes at a lower body weight and younger age than other populations, which makes early screening and lifestyle habits especially important. This guide covers prevention and everyday management in plain language.

This article is general health information, not medical advice. Speak to a qualified doctor or registered dietitian about your own situation, especially if you have a medical condition or take medicines.

What diabetes is

Diabetes means blood sugar (glucose) stays higher than normal. In type 2 diabetes, the body does not respond well to insulin, and over time may not make enough. Type 1 diabetes is an autoimmune condition needing insulin from the start. Gestational diabetes appears in pregnancy. Prediabetes means levels are above normal but not yet in the diabetic range, and it is often reversible.

Know the numbers

Only a doctor can diagnose and set targets for you. Ranges and targets differ by age and health conditions.

Risk factors

• Family history of diabetes.
• Excess belly fat. Waist circumference above about 90 cm in men and 80 cm in women is a common South Asian cut-off. Check BMI with our BMI chart for Indians.
• Inactive lifestyle, poor sleep and chronic stress.
• High blood pressure or cholesterol, and polycystic ovary syndrome in women.
• A history of gestational diabetes.

Adults over 30 with risk factors, and everyone over 35 or 40, should have regular screening. Ask your doctor how often.

Prevention works

Studies of lifestyle programmes, including Indian ones, show that losing 5% to 7% of body weight and exercising about 150 minutes a week can substantially reduce the risk of progressing from prediabetes to diabetes. The same habits manage the condition once it develops.

Eating for blood sugar control

• Plate method: half the plate vegetables, a quarter protein (dal, paneer, eggs, fish, chicken, tofu) and a quarter whole grains such as roti, brown rice, millets or oats.
• Watch portions of rice, roti and sweets, and prefer whole grains, millets and pulses. Use the Indian calorie counter to see portions.
• Add fibre and protein to every meal, which slows the rise in sugar.
• Limit sugary drinks, fruit juices, bakery items, fried snacks and refined flour.
• Eat whole fruit in moderation, not juice.
• Do not skip meals, especially if you take diabetes medicines, since it can cause low sugar.

Move more

• Aim for at least 150 minutes a week of brisk walking, cycling or similar activity, plus two days of strength training.
• A 10 to 15 minute walk after meals helps lower post-meal sugar.
• Break up long sitting time every 30 to 60 minutes.

Check with your doctor before starting new exercise if you have complications, heart problems or take insulin. See yoga for beginners for gentle options.

Monitoring and medicines

• Test blood sugar as often as your doctor advises, and keep a log.
• HbA1c is generally checked every three to six months.
• Take medicines and insulin exactly as prescribed. Do not stop or change doses because you feel well.
• Learn the signs of low blood sugar (sweating, shaking, confusion) and carry a quick source of sugar if you are on medicines that can cause it.

Complications to guard against

• Eyes: yearly dilated eye exam.
• Kidneys: yearly urine and blood tests.
• Feet: check daily for cuts, blisters and sores, and wear proper footwear.
• Heart: control blood pressure and cholesterol, avoid tobacco, and see heart health.
• Teeth and gums, and vaccinations as advised.

When to see a doctor urgently

Seek urgent medical care for extreme thirst, frequent urination, unexplained weight loss, blurred vision, vomiting, fruity-smelling breath, confusion, or a blood sugar reading far outside your target.

Myths

• "Sugar-free" does not mean carbohydrate-free.
• Bitter gourd and herbal remedies do not replace medicines. Tell your doctor about any supplement you take.
• Diabetes is not caused by eating too much sugar alone, but excess calories and weight play a major role.
