Orange is one delicious fruit which is of high nutritional value to human health. It contains rich protein, organic acid, vitamins as well as many essential elements that our body needs such as calcium, phosphorus, magnesium, sodium and potassium, etc.
Orange is high in potassium, therefore kidney failure patients should not eat or at least they can only eat small amount of orange especially if patients have developed serious hyperkalaemia (higher than normal blood potassium level).
Since kidney functions have been severely damaged in the stage of renal failure, the patient’ kidney can not efficiently clear potassium out of body. The excessive building up of potassium in the body will cause muscle weakness and in severe conditions will cause arrhythmia or even heart failure and pose great threaten to the patients’ life, therefore kidney failure patients should have close monitoring of their blood potassium level and in case of hyperkalaemia, seek timely treatment such as the potassium binder. Besides proper treatment and medicines, patients should avoid or at least limit the intake of high-potassium foods.
We know that fresh fruits and vegetables are good for kidney failure patients. however they should avoid those that are high-potassiums. Besides orange, other common foods that are high-potassium include---orange juice, banana, dates, figs, kiwi, peanuts, potatoes, spinach, tomatoes, yogurt, etc.
Some foods such as potatoes can be boiled to help lower its potassium content.
Another thing that needs to be remembered is that orange also contains rich fluid which can add the patient’s fluid intake. In case of edema, high blood pressure, kidney failure patients also need to limit water intake or too much water intake can increase burdens to the kidneys and the heart.
Besides limitation of potassium and water intake, kidney failure patients also need to limit the intake of sodium, protein, phosphorus, purine as well as spicy and stimulating foods for the sake of protecting remaining kidney functions.
