The Link Between Kidney Health & Heart Health

March 10, 2025

Your heart and kidneys are more connected than you might think. The kidneys filter waste and excess fluids from the blood, while the heart pumps oxygen-rich blood throughout the body. When one organ struggles, the other feels the impact.

The Heart-Kidney Connection

When kidney function declines, excess fluids and waste build up, putting extra strain on the heart. Similarly, high blood pressure and heart disease can damage the delicate blood vessels in the kidneys.

People with chronic kidney disease (CKD) are more likely to develop heart disease, and those with heart disease have a higher risk of kidney issues.

Common Risk Factors for Heart and Kidney Disease

Many of the same risk factors contribute to both heart and kidney disease, including:

  • High blood pressure, which can damage blood vessels in the heart and kidneys
  • Diabetes, which can weaken kidney function and increase heart disease risk
  • An unhealthy diet high in sodium, processed foods, and sugary drinks
  • Smoking, which increases the risk of heart disease and worsens kidney function

How to Protect Your Heart & Kidneys

Taking care of your kidneys also helps your heart, and vice versa. Here’s how:

  • Eat a heart-healthy diet focused on whole grains, lean proteins, and healthy fats
  • Stay active with regular exercise to keep blood pressure and weight in check
  • Monitor blood pressure and cholesterol, as high numbers increase risk for both diseases
  • Stay hydrated, as drinking enough water supports kidney function and circulation

Talk to Your Doctor

If you have risk factors for kidney or heart disease, regular check-ups and screenings can help you stay ahead of potential health problems. Managing your blood pressure, cholesterol, and blood sugar levels can protect both organs and keep you feeling your best.

Your heart and kidneys work as a team—let’s take care of them together.
