Affinity Health, a leading provider of high-quality health cover, is highlighting World Kidney Day (12 March) to raise awareness of silent kidney disease — a serious condition that can develop without noticeable symptoms until significant damage has already occurred.
The kidneys play a vital role in maintaining the body’s health. They filter waste and excess fluid from the blood, help regulate blood pressure, support red blood cell production, and maintain healthy bones. Despite this, kidney disease is often described as a “silent condition” because many people feel well until the disease is already advanced.
According to global kidney health organisations, chronic kidney disease affects around 850 million people worldwide, and many remain undiagnosed because the early stages of the disease often have no obvious symptoms.
“Kidney disease often develops quietly, which is why awareness and early testing are so important,” says Murray Hewlett, CEO of Affinity Health.
“Identifying kidney problems early gives people the best chance to slow progression and avoid serious, long-term complications.”
What Is Chronic Kidney Disease?
Chronic kidney disease (CKD) refers to the gradual loss of kidney function. It occurs when the kidneys are damaged and no longer filter blood as effectively as they should. CKD can progress slowly over months or years and may eventually lead to kidney failure if it is not managed.
In its early stages, kidney disease rarely causes noticeable symptoms. This makes regular health checks especially important, particularly for people with known risk factors.
Why Symptoms Often Go Unnoticed
One of the most concerning aspects of kidney disease is how quietly it can develop. The kidneys are highly efficient organs, and even when they are partially damaged, they may continue working well enough to hide warning signs.
Early kidney disease may cause mild or vague symptoms that are easy to dismiss, such as:
- Feeling more tired than usual.
- Mild swelling in the feet or ankles.
- Changes in urination patterns.
- Difficulty concentrating.
Because these symptoms are common and can be linked to many everyday issues, kidney disease is often overlooked until more serious problems arise.
Common Risk Factors for Kidney Disease
Kidney disease can affect anyone, but some people are at a higher risk than others. High blood pressure, diabetes, and heart disease all increase the likelihood of developing kidney problems. A family history of kidney disease, being over the age of 60, and long-term use of certain medications, including some painkillers, can also raise the risk.
People with these risk factors should be especially vigilant about routine health screenings, as early detection can make a meaningful difference.
How Kidney Disease Is Detected
Kidney disease can usually be identified through simple tests, often long before symptoms become severe. These may include:
- Blood tests to assess kidney function.
- Urine tests to check for protein or blood.
- Blood pressure monitoring.
Regular testing allows healthcare providers to spot early changes and begin treatment before permanent damage occurs.
Why Early Detection Matters
When kidney disease is detected early, steps can be taken to protect the remaining kidney function. Treatment may involve managing blood pressure and blood sugar levels, adjusting medications, making practical diet and lifestyle changes, and monitoring kidney health over time.
Early intervention can slow disease progression and reduce the risk of complications such as heart disease, anaemia, and bone disorders. When kidney disease is only diagnosed at a later stage, treatment becomes far more complex and may require dialysis or a kidney transplant.
Kidney Health and Overall Well-being
Kidney disease not only affects the kidneys but is also closely linked to other health conditions, particularly cardiovascular disease. People with kidney disease face a higher risk of heart-related complications, making early diagnosis even more important.
Undiagnosed kidney disease can also impact energy levels, mental well-being, and quality of life, gradually limiting a person’s ability to work, exercise, or manage daily activities.
Simple Steps to Support Kidney Health
While not all kidney diseases can be prevented, healthy habits can help reduce the risk. These include:
- Keeping blood pressure and blood sugar under control.
- Staying well hydrated.
- Eating a balanced diet.
- Avoiding unnecessary or prolonged use of certain medications.
- Attending regular medical check-ups.
