Diabetes Symptoms, Risks, and Why Early Testing Saves Lives

Diabetes is a long-term condition that disrupts how the body produces or uses insulin. Without proper insulin function, the body struggles to manage blood sugar, leading to serious health issues over time. In 2018, around 30.3 million Americans were living with diabetes, most of them with type 2. The condition can cause high blood sugar levels, which may damage blood vessels and nerves if left untreated. Symptoms often include blurred vision, tingling in the hands and feet, and a higher risk of heart attack or stroke.

Doctors use several tests to diagnose diabetes. A fasting blood sugar level of 126 mg/dL or above signals the condition. A random blood sugar test result of 200 mg/dL or higher also confirms it. The A1C test, another common method, measures average blood sugar over time and gives results as a percentage.

The American Diabetes Association advises people over 45 to get tested for diabetes. Those with risk factors, such as obesity, high blood pressure, or a family history of the disease, should consider testing even without symptoms. Early diagnosis is key to managing diabetes and preventing complications. Testing helps identify the condition before it causes long-term harm. This allows for timely treatment and better health outcomes.
