Potassium and Haemodialysis

Potassium is a mineral which is important for the nerves and muscles function. Potassium needs to be maintained at a safe level in the blood. Excessive potassium level in the blood can cause muscle weakness, abnormal heart rates and in extreme cases, heart failure.

Since haemodialysis can only remove a fixed amount of potassium, it is crucial to control the amount accumulated through patients’ dietary intake. Potassium is found mainly in fruits and vegetables, with small quantities found in nuts, dry beans and dairy and meat products. It is important to avoid high potassium food and take low and moderate potassium food in moderation.



AVOID high potassium foods such as

Wholegrain cereals, bread and biscuit.

Nuts, seeds and related products, e.g. chocolate, peanut butter.

Coconuts and related products, e.g. coconut milk, kaya.

All fresh/canned fruit and vegetable juice, herbal medicine drinks, strong tea/coffee, cocoa and malted beverage, milk, wine

Brown sugar, molasses, maple syrup, toffees, liquorice

High potassium salt substitute, bottled sauces, meat and vegetables extract, essence of chicken, stock cube.
