Our kidneys, two bean-shaped organs located just below the rib cage, are often the unsung heroes of our bodies. While their most widely known function is producing urine to filter waste, their role goes
far beyond that, encompassing several vital metabolic processes that keep us healthy.
Unfortunately, kidney disease especially in its early stages often goes unnoticed, leading to a silent progression toward kidney failure, a serious condition that requires constant vigilance. On this Kidney Day, it is important to highlight the critical need for awareness, regular health check-ups and proactive management of kidney health.
Dr Prasun Ghosh, Chairman – Urology, Kidney Transplant and Renal Care at Medanta, Gurugram, shares what you need to know.
The Unsung Heroes: Beyond Filtration
The kidneys function as highly sophisticated filtration systems, constantly removing toxic substances and excess fluids from the blood.
Beyond this, they play a crucial role in maintaining the body’s overall balance. The kidneys help synthesise Vitamin D, which is essential for bone health and immune function. They also produce erythropoietin, a hormone that stimulates the bone marrow to produce red blood cells and helps prevent anaemia.
In addition, the kidneys regulate electrolyte levels by carefully balancing sodium and potassium. This balance is essential for proper nerve and muscle function, blood pressure regulation and maintaining fluid balance in the body.
The Silent Progression: Recognising Subtle Signs
One of the most concerning aspects of kidney disease is that it often begins without noticeable symptoms.
For many individuals, a significant decline in kidney function can occur before any warning signs appear. This leads to a dangerous pattern of underdiagnosis, where the disease may already be advanced by the time symptoms become noticeable.
One of the earliest indicators can be hypertension (high blood pressure), which can both cause kidney damage and result from it.
Other subtle yet important symptoms include persistent puffiness around the eyes, particularly in the morning, and swelling in the legs, ankles or feet. Additional warning signs may include fatigue, reduced urine output, muscle cramps and difficulty concentrating.
These symptoms should never be ignored. They are not simply signs of ageing or everyday tiredness, they could be early signals that the kidneys are under stress.
Seeking medical advice at the earliest sign of concern is essential.
The Power of Prevention: Monitoring and Check-ups
Preventing kidney disease or slowing its progression depends heavily on regular monitoring and timely medical follow-ups.
An annual health check-up is not merely a routine exercise; it is an important opportunity to monitor critical health indicators such as blood pressure, blood sugar levels and basic kidney function tests, including creatinine levels and estimated glomerular filtration rate (GFR).
These routine screenings can help detect potential issues early, allowing doctors to intervene before the condition progresses.
Understanding Stage 3 Chronic Kidney Disease
If the estimated GFR falls between 30 and 59 ml/min, it generally indicates Stage 3 Chronic Kidney Disease (CKD). At this stage, the kidneys are moderately damaged and are not filtering waste as efficiently as they should.
Common symptoms may include:
Persistent fatigue and weakness
Feeling restless
Swelling in the feet, face or body
Itchy, dry skin
Foamy or dark-coloured urine
Frequent muscle cramps
Although this condition requires medical monitoring and management, many people can continue to lead relatively normal lives if it is properly managed.
The urine albumin-to-creatinine ratio is an important test used to diagnose and monitor kidney damage.
Protecting Your Kidney Health
Managing kidney health involves controlling risk factors and adopting healthy lifestyle habits.
Keeping blood pressure and blood sugar levels under control, following a kidney-friendly diet with reduced salt intake, staying well hydrated, avoiding smoking and limiting the frequent use of painkillers can all help slow further kidney damage.
Regular check-ups with a nephrologist are also crucial to ensure kidney function remains stable over time.
This Kidney Day, let us make kidney health a priority. Awareness, early detection and consistent care can go a long way in protecting these vital organs and maintaining overall well-being.
