The following guidelines can help to reduce/prevent the formation of kidney stones:

  1. Drink plenty
  • Drinking fluids will reduce the risk of developing stones.
    • Drink plenty of fluids (preferably water) throughout the day.
    • Aim to drink 3 litres (about 15 glasses) each day so that you can produce pale colored hot environments you may need to drink more and in colder environments and conditions you may need to drink less to produce pale colour urine i.e between yellow and white rather than dark yellow which mean you are dehydrated or white which means you are over hydrated.
    • Reduce your intake of coffee, strong tea; alcohol.
    • Avoid grapefruit juice

Remember to drink extra during hot weather and after exercise!

  1. Your Calcium intake should meet your daily requirements but
    avoid taking too much.
    Aim to take 3-4 servings of calcium rich foods per day

1 calcium portion is found in :

200ml (1 glass) milk or
125g (1 carton) yogurt
1oz cheddar cheese (matchbox size) or
1 bowl milk pudding

so aim at one glass of milk equivalent….
If you take a calcium supplement, discuss this with your doctor and dietitian

  1. Avoid too much salt and salty foods.
  • Choose other flavourings e.g. pepper, herbs, spices and lemon juice.
    • Add only a small amount of salt while cooking.
    • Cut down or avoid use of salty foods e.g. ham, bacon, sausages, black and white puddings, tinned and packet soups, bovril, oxo, marmite and gravy mixes, processed foods e.g. cornbeef, salami.
  1. Do not eat too much protein.
  • Protein is necessary as part of a healthy diet and is found in meat, chicken, fish and dairy products. However, large intakes of protein can also increase the risk of producing kidney stones.

Adult males and females need two portions daily.

2oz cooked lean meat or chicken or
3oz cooked fish or
2 eggs (not more than 7 per week) or
6 tablespoons of cooked peas/beans

  1. If your stone contains oxalate then it is good to avoid oxalate rich


Do not take vitamin C supplements as these can increase the risk of making oxalate stones.
