Diabetes often develops gradually, and early symptoms can be easy to overlook. Recognising the common warning signs early helps guide timely testing and treatment.
Common early symptoms
- Frequent thirst and frequent urination
- Unexplained fatigue or low energy
- Unexplained weight loss or weight gain
- Slow-healing cuts or wounds
- Blurred vision
Who should be tested sooner
A family history of diabetes, being overweight, high blood pressure, or a sedentary lifestyle all raise the likelihood of developing diabetes. The World Health Organization recommends regular screening for people with these risk factors, even before symptoms appear.
Why early diagnosis matters
Untreated high blood sugar can affect the eyes, kidneys, nerves and heart over time. Early diagnosis allows diet, activity and medicine to be planned before complications develop.
What to bring to a consultation
- Any previous blood sugar or HbA1c reports
- A note of symptoms and how long they have been present
- Current medicines
- Family history of diabetes or related conditions
