High blood sugar is often called a “silent” condition because it can develop gradually, without obvious warning at first. Many people dismiss early changes in their body as stress, aging, or lack of sleep. However, when blood glucose levels remain elevated for too long, they can lead to serious health complications. Understanding what diabetes is, who is most at risk, and how high blood sugar presents itself can help you take action early.What Is Diabetes?Diabetes is a chronic condition that affects how your body processes glucose (sugar) in the blood. Glucose is your body’s main source of energy, and it comes from the food you eat. To move glucose from your bloodstream into your cells, your body relies on a hormone called insulin.

When you have diabetes, either:Your body does not produce enough insulin (Type 1 diabetes), orYour body becomes resistant to insulin and cannot use it effectively (Type 2 diabetes).As a result, glucose builds up in the bloodstream instead of being used for energy. Over time, persistently high blood sugar can damage the heart, kidneys, nerves, eyes, and blood vessels.While diabetes can affect anyone, certain groups face a significantly higher risk due to genetics, lifestyle, or metabolic factors.Risk increases with age, especially when physical activity decreases and weight tends to rise.
