To know if you have diabetes, watch for common symptoms such as:

• Increased thirst and dry mouth
• Frequent urination, especially at night
• Feeling very hungry even if you are eating enough
• Unintentional weight loss
• Extreme fatigue or tiredness
• Blurred vision
• Cuts or wounds that heal slowly
• Itchy or dry skin
• Tingling, pain, or numbness in the hands or feet (more common in type 2)
• Genital itching or thrush infections

These symptoms can develop quickly in type 1 diabetes or more gradually in type 2 diabetes, sometimes going unnoticed for years

. If you notice these symptoms, the only way to confirm diabetes is through medical testing. Common tests include:

• A1C test (measures average blood sugar over 2-3 months)
• Fasting plasma glucose test
• Oral glucose tolerance test

If you experience symptoms or are at risk (family history, obesity, age), see a healthcare provider for evaluation and testing

. In summary, monitor for the key symptoms listed above and seek medical testing to know for sure if you have diabetes. Early diagnosis helps manage the condition and prevent complications.
