Swelling in Feet and Ankles: Is It a Sign of Kidney Disease?
Have you ever removed your shoes at the end of the day and noticed deep marks around your ankles? Or felt that your feet look unusually puffy, tight, or heavier than usual? For many people, swelling in the feet and ankles is brushed off as fatigue, long working hours, or ageing. But what if this swelling is your body’s early warning sign of something more serious—like kidney disease?
A Common Problem That’s Often Ignored
Swelling in the feet and ankles is extremely common, especially among working professionals, elderly individuals, and people who spend long hours standing or sitting. Many people ignore it because:
However, persistent swelling is not something your body does without a reason. While sometimes it can be harmless, in other cases it may be one of the earliest visible signs of kidney disease.
What Exactly Causes Feet and Ankle Swelling?
Swelling, medically called edema, happens when excess fluid collects in the tissues. Gravity causes this fluid to settle in the lower parts of the body—mainly the feet and ankles.
Some common day-to-day reasons include:
- Sitting for long hours at work or during travel
- Standing for prolonged periods
- Excess salt intake
- Hot and humid weather
In such cases, swelling usually goes away with rest, leg elevation, or reduced salt intake.
But when swelling becomes regular, worsens over time, or appears along with other symptoms, it may indicate an internal health issue—most importantly, kidney disease.
The Kidney–Swelling Connection: What Most People Don’t Know
Your kidneys are silent workers. Every day, they filter waste, remove excess water, and maintain the perfect balance of fluids and minerals in your body.
- When kidneys are
healthy:
- Extra fluid leaves the body through urine
- Sodium levels stay balanced
- Blood pressure remains controlled
- When kidneys start
failing:
- Excess water is retained
- Sodium builds up in the body
- Protein leaks into urine
This imbalance leads to fluid accumulation in tissues—most commonly seen as swelling in the feet and ankles.
That’s why experienced specialists like Dr. Vijay Patel, Kidney Specialist in South Mumbai, often consider persistent ankle swelling as an important clue during diagnosis.
Can Swelling Be the First Sign of Kidney Disease?
Yes—very often, it is.
Early kidney disease usually has no pain and very few symptoms. Swelling may be one of the first visible signs that something isn’t right.
Many patients visiting a Nephrologist in South Mumbai for swelling are surprised to learn that their kidneys are the root cause.
How Kidney-Related Swelling Feels Different?
Kidney-related swelling has certain typical features:
- Usually affects both feet and ankles
- Is more noticeable by evening
- Leaves a dent when pressed (pitting edema)
- Does not fully go away with rest
- Gradually worsens over weeks or months
In advanced cases, swelling may also appear in:
Other Subtle Symptoms That Often Accompany Swelling
Swelling rarely comes alone. Pay attention if you also notice:
- Foamy or bubbly urine
- Reduced urine output
- Sudden weight gain
- Fatigue or weakness
- Loss of appetite
- Shortness of breath
- Difficulty concentrating
These signs strongly suggest kidney involvement and should prompt a visit to a Kidney Doctor in South Mumbai.
Who Should Be Extra Careful About Swelling?
Certain people are at higher risk of kidney disease and should never ignore swelling:
- People with diabetes
- Those with high blood pressure
- Individuals with a family history of kidney disease
- Elderly adults
- People taking painkillers frequently
For such individuals, routine check-ups with a South Mumbai Nephrologist are extremely important.
How Doctors Diagnose Kidney-Related Swelling?
A Kidney treatment specialist South Mumbai will usually recommend:
- Blood tests (creatinine, urea)
- Urine tests (protein leakage)
- Blood pressure monitoring
- Kidney ultrasound
These simple tests can detect kidney disease early—sometimes before permanent damage occurs.
Can Swelling Be Reversed If Caught Early?
Yes. If kidney disease is diagnosed early:
- Swelling can reduce significantly
- Kidney function can be preserved
- Disease progression can be slowed
This is why early consultation with a Nephrologist in South Mumbai can be life-changing.
What Happens If Kidney Disease Is Ignored?
Without treatment, kidney disease can progress and lead to:
- Severe swelling
- Breathlessness due to fluid in lungs
- Very low urine output
- Need for dialysis
- Kidney transplant
