Every year on the second Thursday of March, the global health community marks World Kidney Day, an annual campaign dedicated to raising awareness about the vital role our kidneys play in keeping us healthy. The initiative highlights the impact of kidney disease and encourages people to learn more about prevention, early detection and ways to support long-term kidney health.
What do your kidneys actually do?
Your kidneys are two bean-shaped organs located in your lower back. Despite their relatively small size, they perform several essential functions that help keep the body in balance.
Healthy kidneys work around the clock to:
- Filter waste products and toxins from the blood
- Remove excess fluid through urine
- Help regulate blood pressure
- Maintain the balance of electrolytes and minerals
- Support the production of red blood cells
When the kidneys stop working properly, waste products and fluids can build up in the body, potentially leading to serious health problems.
Why raising awareness is so important
Kidney disease is often described as a “silent condition” because symptoms may not appear until the disease has progressed. In fact, many people only discover they have kidney disease through routine blood or urine tests.
Globally, it is estimated that around 850 million people are living with chronic kidney disease, making it one of the most common long-term health conditions worldwide.
This is why awareness campaigns like World Kidney Day are so important. By encouraging people to learn about the risk factors and symptoms, healthcare professionals hope more cases can be detected early and treated before serious complications develop.
Symptoms of kidney disease to watch for
Although early stages may not cause obvious symptoms, some signs that could indicate a kidney problem include:
- Persistent tiredness
- Swollen ankles, feet or hands
- Changes in urination (such as needing to go more often)
- Blood or foam in the urine
- Nausea or poor appetite
- Itchy skin or difficulty concentrating
If you notice these symptoms, it’s important to speak to your GP, who may recommend tests to assess your kidney function.
Who is most at risk?
Certain factors can increase the risk of developing kidney disease, including:
- Diabetes
- High blood pressure
- Heart disease
- Obesity
- A family history of kidney disease
People with these risk factors may benefit from regular health checks to monitor kidney function and detect any changes early.
How to protect your kidney health
The good news is that many cases of kidney disease can be prevented or managed with healthy lifestyle choices. Simple steps that support kidney health include:
- Staying physically active
- Maintaining a healthy weight
- Eating a balanced diet
- Reducing salt intake
- Keeping blood pressure and blood sugar levels under control
- Staying well hydrated
- Avoiding smoking
Small changes can make a significant difference in protecting kidney function over time.
Raising awareness this World Kidney Day
World Kidney Day is an opportunity for individuals, healthcare providers and communities to come together and highlight the importance of kidney health. By increasing awareness and encouraging early testing, the campaign aims to reduce the global impact of kidney disease and improve outcomes for those affected.
Taking care of your kidneys doesn’t have to be complicated — but understanding how they work and recognising potential warning signs can help you stay healthier for longer.
