Understanding Diabetes: Symptoms, Testing, and Prevention
Diabetes can affect people in different ways. Some experience clear symptoms, while others may have signs so mild that they go unnoticed. Knowing what to look for can help with early detection and reduce the risk of complications.
Common symptoms of diabetes include:
-
Frequent urination
-
Excessive thirst
-
Feeling unusually hungry, even after meals
-
Extreme fatigue
-
Blurry vision
-
Cuts or bruises that take a long time to heal
-
Unexplained weight loss (especially in type 1 diabetes)
-
Tingling, pain, or numbness in the hands or feet (common in type 2 diabetes)
If you notice any of these signs, it’s important to get tested. Diabetes testing is typically done in a healthcare setting, such as your doctor’s office or a lab. In some cases, if blood sugar levels are very high or classic symptoms are present alongside a positive test, a second test may not be necessary for diagnosis.
Preventing diabetes is possible
We’re committed to helping reduce the incidence of diabetes. That’s why we partner with the CDC’s National Diabetes Prevention Program (National DPP). This program offers a structured, research-based lifestyle change plan proven to help prevent or delay type 2 diabetes.
What about prediabetes?
Prediabetes means your blood sugar is higher than normal, but not high enough to be diagnosed with diabetes. While it doesn’t guarantee you’ll develop diabetes, it’s a sign to take action—through healthy eating, physical activity, and lifestyle changes—to lower your risk.
Early detection and proactive steps can make a big difference. Paying attention to symptoms and taking advantage of prevention programs can help you stay healthy and reduce your risk of diabetes-related complications.
