Can type 2 diabetes cause stroke?

A stroke happens when part of the brain loses its blood supply or when a blood vessel bleeds. Diabetes can affect the inner lining of blood vessels and promote narrowing, while related conditions can add strain to the circulation. A stroke may cause sudden weakness or numbness on one side, a drooping face, slurred or confused speech, vision loss, severe dizziness or difficulty walking. Symptoms can improve briefly and still require emergency assessment.

Attend diabetes reviews and take prescribed glucose, blood pressure or cholesterol medicines as directed. Ask for a personalised plan covering food, activity, sleep and smoking cessation. Know your usual readings and bring a medicine list to appointments. Do not stop medicines because you feel well. Managing these factors supports blood vessel health, but it cannot remove every cause of stroke.

Call emergency services immediately for sudden facial drooping, arm or leg weakness, speech difficulty, new vision loss, severe imbalance or an unexplained severe headache. Note the time the person was last known well, keep them safe and do not give food, drink or medicines unless instructed. Do not drive them yourself if an ambulance is available, because rapid assessment affects treatment options.

Ask how your glucose, blood pressure and cholesterol readings affect your vascular plan, whether your medicines need review, and what activity is suitable for you. Request clear advice about smoking cessation and the warning symptoms that should trigger an emergency call.
