Chronic kidney disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste and excess fluid from the blood. Because the disease often develops slowly, many people do not realise they have it until it has reached an advanced stage.
Health experts say early detection and proper treatment can help slow the progression of chronic kidney disease and reduce the risk of kidney failure.
What Is Chronic Kidney Disease?
Chronic kidney disease occurs when the kidneys become damaged over several months or years.
Healthy kidneys remove waste products, balance fluids and minerals, regulate blood pressure, and produce hormones that help maintain healthy bones and red blood cells.
When kidney function declines, waste products can build up in the body, affecting many organs.
What Causes Chronic Kidney Disease?
The most common causes include:
- Diabetes.
- High blood pressure.
- Recurrent kidney infections.
- Polycystic kidney disease.
- Long-term blockage of the urinary tract.
- Autoimmune diseases, such as lupus.
- Long-term overuse of certain medications, including some pain relievers.
In many cases, more than one factor contributes to kidney damage.
Early Symptoms
CKD often causes no symptoms in its early stages.
As kidney function worsens, symptoms may include:
- Persistent fatigue.
- Swelling of the feet, ankles, or hands.
- Frequent urination, especially at night.
- Blood or foam in the urine.
- Poor appetite.
- Nausea.
- Muscle cramps.
- Dry, itchy skin.
- Difficulty concentrating.
- High blood pressure that is difficult to control.
These symptoms can also occur in other medical conditions.
Who Is Most at Risk?
People at increased risk include those with:
- Diabetes.
- High blood pressure.
- Heart disease.
- Obesity.
- A family history of kidney disease.
- Age over 60 years.
- A history of smoking.
Regular screening is especially important for these groups.
How Is Chronic Kidney Disease Diagnosed?
A healthcare provider may recommend:
- Blood tests to measure kidney function.
- Urine tests to check for protein or blood.
- Blood pressure measurement.
- Kidney ultrasound or other imaging tests.
- Additional tests to identify the underlying cause.
CKD is usually diagnosed based on kidney abnormalities that persist for at least three months.
Treatment Options
Although there is no cure for chronic kidney disease, treatment can slow its progression.
Treatment may include:
- Controlling blood pressure.
- Managing diabetes.
- Prescribed medications to protect kidney function.
- Dietary changes, including reducing salt intake.
- Regular exercise.
- Avoiding smoking.
- Treating the underlying cause whenever possible.
In advanced stages, dialysis or a kidney transplant may become necessary.
Can Chronic Kidney Disease Be Prevented?
Many cases can be prevented or delayed by:
- Maintaining healthy blood pressure.
- Keeping blood sugar under control.
- Drinking enough water.
- Eating a balanced diet.
- Exercising regularly.
- Avoiding unnecessary use of certain painkillers.
- Attending regular medical check-ups.
When Should You See a Doctor?
Seek medical advice if you experience:
- Persistent swelling.
- Blood in your urine.
- Changes in urination.
- Ongoing fatigue.
- High blood pressure.
- A family history of kidney disease.
Early diagnosis allows treatment to begin before severe kidney damage occurs.
The Bottom Line
Chronic kidney disease is a serious condition that develops gradually and often goes unnoticed in its early stages. Diabetes and high blood pressure are the leading causes, but early detection, healthy lifestyle choices, and proper medical treatment can help slow disease progression and protect kidney function. Regular screening is particularly important for people at higher risk.
