Early onset type 2 diabetes: what to know

Early onset type 2 diabetes means high blood glucose developing earlier in adult life and needing active management. It happens when insulin does not work effectively and the body cannot keep glucose within a healthy range. Some people have few symptoms, so testing can matter even when they feel well.

Possible signs include increased thirst, passing urine often, tiredness, blurred vision, slow-healing cuts or repeated infections. Prediabetes can precede diabetes, but not everyone notices it. Over time, high glucose can affect nerves, kidneys, blood vessels, eyes and the skin. Peripheral Neuropathy may cause tingling or reduced sensation; Chronic Kidney Disease and Peripheral Arterial Disease are among complications clinicians monitor. These problems are risks to manage, not predictions about one person.

Arrange a GP review for symptoms or a concerning screening result. Testing may include blood glucose measures and a longer-term glucose marker. Follow the agreed plan for food, activity, medicines and home checks. Look after feet daily, attend recommended eye and kidney checks, and treat cuts promptly. Ask for support that fits your routine rather than making abrupt changes you cannot maintain.

Seek urgent help for vomiting with severe thirst, deep or rapid breathing, marked drowsiness, confusion, fainting, or inability to keep fluids down. Get prompt advice for a foot wound, spreading redness, warmth or swelling, or sudden weakness, facial drooping or speech difficulty. Hypoglycaemia can cause sweating, shaking, hunger, confusion or unusual behaviour, especially with glucose-lowering treatment.

Ask what your results mean, which glucose targets apply to you, how to recognise and treat Hypoglycaemia, and when kidney, eye, foot and cardiovascular checks are due. Discuss whether weight, blood pressure or cholesterol needs attention and how to adjust treatment during illness.
