Did you know high blood pressure is one of the leading causes of kidney damage? For people with diabetes, keeping blood pressure in check is especially important to protect kidney health.
In this article, we'll explain how high blood pressure affects your kidneys, share practical tips, and provide key statistics to help you take control of your health.
Understanding the Impact of Blood Pressure on Kidney Damage
Your kidneys filter waste and excess fluids from your blood, helping keep your body in balance. But when blood pressure is too high, it puts extra strain on these organs. Over time, this can cause chronic kidney disease (CKD) - and if left untreated, it may even lead to kidney failure.
High blood pressure damages the small blood vessels in your kidneys, reducing their ability to filter blood effectively. For people with diabetes, the risk is even higher because those tiny blood vessels are already under extra strain.
High blood pressure in the UK: Key facts
Around 14.4 million people in the UK are estimated to have high blood pressure.
30% of adults in England live with high blood pressure - many without knowing it.
High blood pressure contributes to 50% of chronic kidney disease cases.
How to Prevent Your Kidney Damage from High Blood Pressure
What you eat has a big effect on your blood pressure and kidney health. Try these tips:
Cut down on salt:
Aim for less than 6g a day(about a teaspoon)
Eat more fruit and vegetables:
Packed with potassium to balance; aim for at least five portions daily
Choose whole grains:
Opt for wholemeal bread, brown rice and oats
Avoid processed foods:
These often contain hidden salt and sugar
Stay physically active:
You don't need a gym membership - even a brisk 30-minute walk each day can lower blood pressure and support kidney health.
Monitor your blood pressure:
Regular checks help you stay on top of your numbers and take action early if needed.
Stay hydrated:
Drink 6-8 glasses of water daily (unless your doctor advises otherwise) to help your kidneys flush out toxins.
Manage stress:
Stress can raise your blood pressure. Deep breathing, yoga, or meditation can help keep stress levels in check.
Quit smoking:
Smoking damages blood vessels and raises blood pressure, increasing your risk of kidney disease. If you smoke, seek support to quit.
