Te tiaki i ō whanewhane

Having healthy kidneys is important for your general health and wellbeing. Making healthy lifestyle choices can help to keep your kidney healthy.

If you have chronic kidney disease (CKD), making healthy lifestyle choices can help to prevent further kidney damage.

You can keep your kidneys as healthy as possible by making any of these changes that apply to you.

Keep your blood pressure under control

If the blood vessels in your kidneys are damaged, they may stop removing wastes and extra fluid from your body. Having extra fluid in your blood vessels may then raise your blood pressure even more, creating a dangerous cycle.

Keeping your blood pressure under control is the most important thing you can do to look after your kidneys. Eating well, staying a healthy weight, keeping physically active and taking any medicine prescribed by your doctor will all help you do this.
