Diet and kidney Disease in Singapore2017-03-17 18:27
1. Potassium intake
When your kidneys are not functioning well, blood potassium level can rise too high and cause weak heart, fatigue and poor respiration. In the early stage of kidney disease, you may need to restrict your potassium intake if you experience high blood potassium level. It is also important to limit your intake of potassium from diet even when you commence dialysis to prevent the complications. Your dietitian will work with you regarding the suitable foods to be included in your diet.
2. Phosphate intake
Phosphate is one type of mineral which tends to build up in your blood when your kidneys are not working properly. High phosphate level in the blood attracts calcium from bones, which leads to weak bones, joint pain, itchiness of skin and hardening of blood vessels. It is recommended to limit your phosphate intake from diet if your blood phosphate level is elevated. Your dietitian will work with you for suitable food substitution for the high phosphate foods. If you are prescribed phosphate binders, it is important that you take these with your meals to reduce the absorption of phosphate from your foods.
3. Sodium intake
Too much sodium can make you thirsty, making it difficult to control your fluid intake. Sodium also retains fluid in your body, causing swelling and worsening of blood pressure.
4. Fluid intake
As your kidney disease progresses, water builds up quickly in the body as a result of decreased urine output. Too much fluid retention may cause ankle or leg swelling, difficult in breathing and increase blood pressure. Check with your dietitian or doctor about your daily fluid allowance.
5. Adhere to the principle of balanced diet
You need a variety of foods to meet your body’s requirements. Your dietitian will work with you to ensure you eat suitable amounts and types of food from each of the food groups.
