Type 2 diabetes develops when the body cannot use insulin effectively, leading to high blood sugar. It is very common in India and often develops gradually. Early detection and good daily habits make a big difference to long-term health.
Early signs
Increased thirst and urination, tiredness, blurred vision, slow-healing wounds and frequent infections. Many people have no clear symptoms early on, which is why screening matters if you are at risk.
Who is at higher risk
A family history of diabetes, being overweight (especially around the abdomen), physical inactivity, high blood pressure and a history of gestational diabetes all raise risk. Risk also rises with age.
Prevention and management
A balanced, portion-controlled diet, regular physical activity, healthy weight and not smoking help prevent and manage diabetes. If diagnosed, regular monitoring, follow-up and any prescribed medicines keep blood sugar controlled and protect your heart, kidneys, eyes and nerves.
