Common symptoms of type 2 diabetes

Type 2 diabetes develops when the body does not use insulin effectively and blood glucose remains too high. Some people notice thirst, passing urine often, tiredness, blurred vision, dry or itchy skin, or repeated infections. Cuts may take longer to heal, and tingling or reduced sensation in the feet can develop over time. Symptoms may be mild or absent, so feeling well does not rule out the condition.

A symptom alone cannot diagnose diabetes. Prediabetes may have few noticeable symptoms, while nerve, kidney and circulation problems can occur when glucose remains high over time.

Arrange a medical appointment if these changes are new, persistent or occurring together. A clinician can review your history and arrange suitable glucose testing. Keep a note of thirst, urination, vision changes, infections, wounds and medicines. Do not stop prescribed treatment without advice. Foot care, balanced meals, activity suited to your health and follow-up can reduce the chance of complications.

Seek urgent care for vomiting, severe weakness, confusion, difficulty breathing, fainting, sudden vision loss or a wound that is rapidly red, swollen or painful. Sudden facial drooping, arm weakness or speech difficulty may indicate a [Stroke](/conditions/stroke/) and needs emergency help. A spreading skin infection may be [Cellulitis](/conditions/cellulitis/).

Ask which tests are appropriate, how often your glucose should be checked, whether your medicines could affect symptoms, and how to protect your feet, eyes, kidneys and heart. Mention any family history, pregnancy, recent illness and changes in weight or activity.
