Type 2 diabetes can develop gradually, and some people have few noticeable symptoms. A blood test is used to assess blood glucose; a consultation helps interpret results alongside your health history.
Type 2 diabetes can develop gradually, with few noticeable symptoms for some people. A blood test helps assess blood glucose. Your clinician can explain the result in the context of your health history.
What symptoms can occur?
Possible symptoms include increased thirst, passing urine more often, tiredness, unintended weight loss, blurred vision or recurrent infections. These symptoms can have other causes and cannot diagnose diabetes. Tell a clinician when they began and whether they are changing.
Who should discuss testing?
Ask a healthcare professional about testing if you have concerning symptoms or risk factors such as a family history of diabetes. They can consider age, medical history, weight and other factors when advising on tests and follow-up. Do not assume a normal feeling means a test is unnecessary.
How is diabetes assessed?
A clinician may recommend a blood test, explain the result and decide whether repeat testing or other assessment is needed. Bring previous results and a medication list. Ask what the test measures, whether any preparation is needed and when you should expect the result.
What if diabetes is diagnosed?
Care can involve food choices, physical activity, monitoring and sometimes medication, tailored to your needs. Ask about follow-up, blood pressure, eye and foot care, and whom to contact with concerns. If you feel seriously unwell, have persistent vomiting or become confused, seek urgent medical help rather than waiting for a routine appointment.
