Common symptoms of type 2 diabetes

  • Feeling very thirsty and drinking more than usual
  • Peeing more often, especially at night
  • Feeling more tired than usual
  • Unexplained weight loss
  • Blurred vision
  • Cuts or wounds that heal slowly
  • Recurrent infections (e.g. thrush)
  • Tingling or numbness in hands or feet

Many people have no symptoms at all in the early stages — which is why risk-checking and blood tests matter.

Who is most at risk?

Risk is higher if you’re over 40 (or over 25 in some ethnic groups), carry excess weight around your middle, are physically inactive, have a family history of diabetes, have had high blood pressure or high blood glucose, or had gestational diabetes. Some South Asian, African-Caribbean and Middle Eastern backgrounds carry higher risk from a younger age.

When to see a doctor

See your GP if you have any of the symptoms above, or if a risk check suggests moderate-or-higher risk. A simple blood test (usually HbA1c) can show whether your blood sugar is raised. Catching prediabetes early gives the best chance to prevent type 2 diabetes.

The good news

Much of the risk is modifiable. Losing 5–10% of body weight, moving more, improving diet and stopping smoking can substantially lower your chance of developing type 2 diabetes — and can even push prediabetes back toward normal.
