Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste products and excess fluids from the blood. The disease often develops silently, and many people may not notice any symptoms during its early stages. As kidney function declines, however, waste and fluid can build up in the body and affect overall health.
Diabetes and high blood pressure are among the leading risk factors for CKD. Other causes include inherited kidney disorders, repeated kidney infections and certain autoimmune conditions. Recognising possible warning signs and getting appropriate medical tests can help detect kidney problems early and slow the progression of the disease.
Seven Warning Signs of Chronic Kidney Disease
As kidney function declines, the body may begin showing changes that should not be overlooked. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), possible symptoms include swelling, changes in urination, fatigue and difficulty concentrating.
- Swelling in the Feet, Ankles and Hands
When the kidneys cannot remove excess salt and fluid effectively, it may accumulate in the body. This can cause swelling in the feet, ankles, legs, hands or sometimes the face. Persistent or unexplained swelling needs medical attention.
- Changes in Urination
A noticeable change in urination frequency or volume may indicate a kidney or urinary tract problem. Some people may need to urinate more frequently, particularly at night, while others may pass less urine than usual.
- Foamy or Bubbly Urine
Urine that repeatedly appears unusually foamy or bubbly may indicate excess protein in the urine. This condition, known as proteinuria, can be an early sign of kidney damage. However, occasional foam does not necessarily indicate kidney disease.
- Persistent Fatigue and Weakness
Damaged kidneys may produce less erythropoietin, a hormone that helps the body make red blood cells. This can contribute to anaemia, leaving a person feeling unusually tired, weak or short of energy.
- Loss of Appetite, Nausea and Vomiting
As kidney function deteriorates, waste products may accumulate in the bloodstream. This can cause nausea, vomiting, a reduced appetite and sometimes an unpleasant taste in the mouth.
- Dry and Itchy Skin
Persistent itching and dry skin can occur in advanced kidney disease. Changes in mineral balance and the accumulation of waste products may contribute to these symptoms.
- Shortness of Breath and Sleep Problems
Fluid accumulation in the body can sometimes affect the lungs and make breathing difficult. Anaemia and other complications may also contribute to breathlessness. Some people experience difficulty sleeping, restless legs or muscle cramps as kidney disease progresses.
Who Is at Higher Risk of Chronic Kidney Disease?
Although CKD can affect people of different ages, certain health conditions and lifestyle factors increase the risk. Diabetes and high blood pressure are among its major causes because they can damage the kidneys’ small blood vessels over time.
Other risk factors include:
- Family history of kidney disease or kidney failure.
- Heart and blood vessel diseases.
- Obesity and certain metabolic conditions.
- Recurrent kidney infections or kidney stones.
- Autoimmune conditions that affect the kidneys.
- Long-term or inappropriate use of certain medicines, particularly some painkillers.
People with diabetes, high blood pressure or a family history of kidney disease should discuss regular kidney testing with their healthcare professionals.
How Is Chronic Kidney Disease Diagnosed and Managed?
Symptoms alone cannot confirm CKD because many of them can also occur due to other medical conditions. Doctors generally use blood and urine tests to assess kidney health.
A blood test measuring creatinine helps estimate the glomerular filtration rate (eGFR), which indicates how effectively the kidneys filter waste. A urine albumin test checks whether protein is leaking into the urine. Doctors may recommend additional investigations depending on the patient’s condition.
Although CKD may not always be reversible, early diagnosis and appropriate treatment can help slow its progression. Managing blood pressure and blood sugar, following medical advice, maintaining a balanced diet and avoiding unnecessary medicines that may harm the kidneys are important steps.
Conclusion
Chronic Kidney Disease often develops without noticeable symptoms in its early stages, making awareness and regular health check-ups particularly important. Swelling, changes in urination, persistent fatigue, foamy urine and unexplained nausea are some warning signs that deserve medical attention.
People with diabetes, high blood pressure or a family history of kidney disease should be especially careful about monitoring their kidney health. Early detection, timely medical consultation and appropriate treatment can help protect kidney function and improve long-term health.
Remember: The presence of these symptoms does not automatically mean someone has CKD. Only appropriate medical evaluation and testing can establish the diagnosis.
