Type 2 diabetes develops when the body does not use insulin well and blood sugar rises over time. Many people have no symptoms for years, which is why knowing your risk matters.
Factors that raise risk include a family history of diabetes, extra body weight, low physical activity and older age. Some people with high blood sugar notice more thirst, frequent urination, tiredness, blurry vision or sores that heal slowly, but these signs can have other causes too.
A simple blood test can check blood sugar levels, and only a healthcare professional can diagnose diabetes. Talk to your doctor about whether you should be screened and how often, especially if you have any of the risk factors above.
