Diabetes Linked to Silent Heart Damage and Early Warning Signs

Cardiologist Dr. Dibanšu Gupta explains that diabetes can silently damage blood vessels, nerves and the heart muscle long before any symptoms appear. Elevated blood sugar promotes atherosclerotic plaque buildup and a condition called diabetic cardiomyopathy, which reduces the heart's pumping ability and can lead to heart attacks or strokes that may be atypically mild or painless.

Early stages of diabetes often present subtle cues that are easily missed. Common early signs include frequent urination, increased thirst, persistent hunger, chronic fatigue, unexplained weight loss, blurred vision, dry or itchy skin, slow‑healing wounds, and tingling or numbness in the hands and feet. Recognising these symptoms and undergoing blood‑sugar testing can enable timely intervention.

Regular health monitoring—checking blood glucose, blood pressure, cholesterol, kidney function and, for higher‑risk individuals, electrocardiograms or cardiac ultrasounds—is essential to detect complications early and reduce long‑term cardiovascular risk.
