Can prediabetes cause type 2 diabetes?

In prediabetes, the body does not respond to insulin as effectively as it should, so glucose remains in the bloodstream more readily. The pancreas may compensate by making more insulin, but this response can become less effective. If blood glucose stays elevated, it may cross the diagnostic range for type 2 diabetes. Prediabetes does not make diabetes inevitable; it is a warning stage that gives you an opportunity to review your health with a clinician.

Arrange regular glucose checks recommended by your clinician and keep a record of results. Regular movement, balanced meals with fibre-rich foods, and attention to portion sizes can support glucose control. If you smoke, ask about support to stop. Medicines may be considered for some people, depending on their health history and glucose pattern.

Book a medical review if testing shows rising glucose, or if you develop increased thirst, frequent urination, unusual tiredness, blurred vision, or unexplained weight loss. Seek urgent help for vomiting, severe weakness, confusion, or difficulty staying awake, especially when diabetes is known or suspected.

Ask which glucose test you need, how often it should be repeated, and what result would change your plan. You can also ask whether medicines, a dietitian referral, or a structured activity plan would suit your health needs.
