Swelling in the legs, ankles, or feet is a common health concern that can range from a temporary issue to a sign of an underlying medical condition. Medically known as peripheral edema, leg swelling occurs when excess fluid accumulates in the body's tissues. While prolonged standing, travel, or hot weather can cause mild swelling, persistent or recurrent fluid retention should never be ignored.
Dr. Bhupeshkumar Kaware, a leading Consultant Nephrologist & Transplant Specialist in Viman Nagar, Pune, specializes in diagnosing and managing kidney-related causes of fluid retention and swelling, helping patients achieve better health and quality of life.
What Is Fluid Retention?
Fluid retention, also known as edema, occurs when the body holds onto excess fluid instead of removing it through normal processes such as urination and circulation. This can lead to visible swelling, particularly in the legs, ankles, feet, and sometimes the hands or face.
The condition may affect one or both legs and can vary from mild puffiness to significant swelling that interferes with mobility and daily activities.
Common Causes of Swelling in the Legs
Several factors can contribute to leg swelling. Identifying the underlying cause is essential for effective treatment.
- Kidney Disease - The kidneys play a vital role in regulating fluid balance. When kidney function is impaired, excess fluid and sodium can accumulate in the body, leading to swelling in the legs, ankles, and around the eyes.
- Chronic Kidney Disease (CKD) - Patients with chronic kidney disease often experience fluid retention due to reduced kidney function. Early diagnosis and management are crucial to prevent complications.
- Nephrotic Syndrome - This kidney disorder causes excessive protein loss in the urine, leading to significant swelling, especially in the legs and feet.
- Heart Conditions - Heart failure can reduce the heart's ability to pump blood effectively, causing fluid buildup in the lower limbs.
- Liver Disease - Liver disorders can affect protein production and fluid regulation, contributing to swelling.
- Venous Insufficiency - Poor blood flow in the leg veins may cause fluid accumulation and swelling, particularly after standing for long periods.
- Medications - Certain medications, including blood pressure medicines, steroids, and some diabetes treatments, may cause fluid retention as a side effect.
- Pregnancy - Mild swelling is common during pregnancy, but sudden or severe swelling should be evaluated by a healthcare professional.
Symptoms Associated with Fluid Retention
In addition to visible swelling, patients may experience:
- Tightness or heaviness in the legs
- Puffiness around the ankles and feet
- Difficulty fitting into shoes
- Skin that appears stretched or shiny
- Weight gain due to fluid accumulation
- Reduced mobility or discomfort while walking
In some cases, swelling may indicate a more serious medical condition requiring prompt evaluation.
When Should You Seek Medical Attention?
You should consult a healthcare specialist if:
- Swelling persists for several days
- One leg becomes significantly more swollen than the other
- Swelling is accompanied by shortness of breath
- You have known kidney, heart, or liver disease
- There is pain, redness, or warmth in the affected leg
- You notice sudden weight gain due to fluid retention
Early diagnosis can help identify potentially serious underlying causes and prevent complications.
How Is the Cause of Leg Swelling Diagnosed?
A comprehensive evaluation may include:
- Medical History and Physical Examination - Assessment of symptoms, lifestyle factors, and existing medical conditions.
- Blood Tests - To evaluate kidney function, liver function, electrolyte balance, and protein levels.
- Urine Tests - To detect protein leakage and assess kidney health.
- Ultrasound Studies - To evaluate blood flow and rule out vein-related problems.
- Imaging Investigations - Additional tests may be recommended depending on the suspected cause.
At Dr. Bhupeshkumar Kaware’s clinic in Viman Nagar, Pune, patients receive a thorough assessment to determine the exact reason for fluid retention and swelling.

- Maintaining a healthy weight
- Following a balanced diet
- Limiting excessive salt consumption
- Undergoing regular health checkups, especially if you have kidney disease
Frequently Asked Questions
Is leg swelling always related to kidney disease?
No. Leg swelling can result from kidney disease, heart conditions, liver disorders, vein problems, medications, or lifestyle factors.
Can drinking too much water cause swelling?
In people with healthy kidneys, excess water is usually removed effectively. However, individuals with kidney, heart, or liver disease may develop fluid retention.
Does reducing salt intake help with swelling?
Yes. Excess salt causes the body to retain water, making swelling worse.
When is leg swelling considered an emergency?
Seek immediate medical attention if swelling is accompanied by chest pain, severe shortness of breath, sudden onset, or symptoms suggestive of a blood clot.
Swelling in the legs and fluid retention can be early signs of underlying kidney disease or other serious health conditions. Identifying the cause and receiving timely treatment is essential for preventing complications and maintaining overall health.
