Preventing chronic kidney disease 

How to take care of your kidneys

Your kidneys process a huge volume of fluids and chemicals. Simple lifestyle changes can help keep them functioning healthily.

Kidney risk calculator

There is now a calculator you can use to work out your risk of developing moderate to severe kidney disease over the next five years. You just need to answer some simple questions.

Use the QKidney Web Calculator.

You may wish to use the tool during your next GP or practice nurse consultation.

The calculator is only valid if you do not already have a diagnosis of chronic kidney disease, stage 3b or worse. Ask your doctor if you are unsure.

Managing your condition

If you have a chronic (long-term) condition, such as diabetes, that could potentially cause chronic kidney disease, it is important that it is carefully managed.

Follow the advice of your GP and keep all appointments relating to your condition. People with diabetes are advised to have their kidney function tested every year.

See the Health A-Z topics on Type 1 diabetes and Type 2 diabetes for more information about how to manage diabetes.

Smoking

Smoking increases your risk of cardiovascular disease, including heart attacks or strokes, and it can increase the likelihood that any existing kidney problems will get worse.

If you stop smoking, you will improve your general health and reduce your risk of developing other serious conditions, such as lung cancer and heart disease.

The NHS smoking helpline can offer you advice and encouragement to help you quit smoking. Call 0800 022 4 332 or visit the NHS Smokefree website. For more information, see the Live Well topic about Stopping smoking.

Diet

A healthy diet is important for preventing chronic kidney disease (CKD). It will lower the amount of cholesterol in your blood and keep your blood pressure at a healthy level. Eat a balanced diet that includes plenty of fresh fruit and vegetables (five portions a day) and whole grains.

Limit the amount of salt in your diet to no more than 6g (0.2oz) a day. Too much salt will increase your blood pressure. One teaspoonful of salt is equal to about 6g.

Avoid eating foods that are high in saturated fat because this will increase your cholesterol level.

Foods that are high in saturated fat include:

  • meat pies 
  • sausages and fatty cuts of meat 
  • butter 
  • ghee (a type of butter often used in Indian cooking) 
  • lard 
  • cream 
  • hard cheese 
  • cakes and biscuits 
  • foods that contain coconut oil or palm oil

Eating some foods that are high in unsaturated fat can help decrease your cholesterol level. Foods that are high in unsaturated fat include:

  • oily fish 
  • avocados 
  • nuts and seeds 
  • sunflower oil
  • rapeseed oil
  • olive oil

See the Health A-Z topic on Diet for more information and advice about eating healthily.

Alcohol

Drinking excessive amounts of alcohol will cause your blood pressure to rise, as well as raising the cholesterol levels in your blood. Therefore, sticking to the recommended alcohol consumption limits is the best way to reduce your risk of developing high blood pressure (hypertension) and CKD.

The recommended limits for alcohol are:

  • 3–4 units of alcohol a day for men 
  • 2–3 units of alcohol a day for women

A unit of alcohol is equal to about half a pint of normal strength lager, a small glass of wine or a pub measure (25ml) of spirits. For more information, see the Live Well topic on Alcohol.

Exercise

Regular exercise should help lower your blood pressure and reduce your risk of developing CKD.

At least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity (i.e. cycling or fast walking) every week, is recommended. 

See the Health A-Z topic on Exercise for information and advice about exercising with a chronic (long-term) health condition. Also see the Live Well section on Health and fitness.
