Prevention & life stages

Preventing Type 2 Diabetes

Type 2 diabetes can often be delayed or prevented by reaching a healthy weight, eating well and staying active — especially if you are at higher risk.

What it means

Type 2 diabetes develops when the body cannot use insulin properly and blood sugar rises. Prevention focuses on the risk factors you can change — mainly weight, diet and activity — particularly in people at higher risk or with "prediabetes".

Why it matters

Type 2 diabetes can lead to serious problems with the eyes, kidneys, nerves, heart and circulation. Much of it is preventable, and people at high risk can substantially cut their chances by changing their lifestyle.

Practical tips

How to make it work

  • Reach and keep a healthy weight — even modest weight loss greatly lowers risk if you are overweight.
  • Eat a balanced diet with plenty of vegetables, wholegrains and pulses, and less sugar, refined carbohydrate and processed food.
  • Be physically active — aim for at least 150 minutes a week.
  • Cut down on sugary drinks and snacks.
  • Know your risk — a check can identify prediabetes early.
  • If offered a diabetes prevention programme, take part, as these are proven to help.

Good to know. People of South Asian, African-Caribbean and some other backgrounds, and those with a family history, develop type 2 diabetes at lower weights and younger ages, so may need to act earlier. See your GP if you have symptoms such as thirst, tiredness or passing lots of urine.
