Swelling & Oedema

Swelling (oedema) happens when fluid shifts out of the blood vessels and collects in the tissues. It is one of the commonest reasons people seek a medical opinion — a puffy ankle in the evening, a tight ring in the morning, or feet that will not fit into shoes. Swelling is a symptom, not a diagnosis: the same appearance can come from something harmless and temporary, or from a problem with the heart, kidneys, liver, blood vessels, thyroid or medicines. The aim of this service is to work out why the swelling is happening, treat the underlying cause, and recognise quickly when it signals something that needs urgent attention.

This service covers the full range of swelling and fluid-retention concerns seen in an Internal Medicine / General Physician practice — swelling of the feet and ankles, leg swelling (one-sided and both-sided), facial and eyelid swelling, generalised body swelling, fluid retention, sudden and persistent swelling, swelling with breathlessness, swelling related to kidney problems, swelling in diabetes, swelling with high blood pressure, medication-related swelling, and swelling alongside abnormal kidney tests. Where the cause overlaps with kidney, heart, liver, thyroid or diabetes care, Dr. Nayak connects the assessment and treatment across the relevant services.

Understanding swelling and oedema

Oedema is the medical word for fluid collecting in tissues. It is described by its distribution — peripheral (feet, ankles and legs), dependent (worse in the lowest part of the body with gravity, easing when raised), facial, or generalised (widespread, including the abdomen and sometimes fluid around the lungs) — and by whether it is pitting (a finger-press leaves a dent that slowly fills) or non-pitting. A doctor also checks whether it is one-sided or both-sided, how quickly it came on, and whether it is accompanied by breathlessness, reduced urine output, weight change or other symptoms. These features together point toward the likely cause far more reliably than the swelling alone.

Common patient concerns

Most people come in for one of a few reasons: shoes or slippers that have become tight, ankles that swell as the day goes on, a puffy face or eyes on waking, one leg that has swollen suddenly, swelling that has appeared with breathlessness, or swelling found alongside an abnormal kidney or blood-pressure report. Some are reassured to learn the cause is benign; others are rightly concerned that it signals a heart, kidney or liver problem. Each pattern is explored on its own page below.

Swelling of feet and ankles

Swelling of the feet and ankles is the commonest form of swelling. Both-sided ankle swelling that worsens through the day and eases overnight is often dependent oedema from prolonged standing, venous pooling, early heart or kidney issues, or medicines. New or worsening foot and ankle swelling always needs assessment when it is persistent, one-sided, accompanied by breathlessness, or associated with reduced urine output. See Swollen Feet for the focused explanation.

Leg swelling

Leg swelling extends beyond the ankle into the calf or thigh. The single most important distinction is whether it affects one leg or both: both-sided leg swelling usually points to a systemic cause (heart, kidneys, liver, medicines, venous insufficiency), while one-sided leg swelling raises the possibility of a clot in the deep veins (deep vein thrombosis) or a local problem, and can need urgent assessment. See Leg Swelling, Bilateral Leg Swelling and One-sided Leg Swelling for the distinct approaches.

Facial and eyelid swelling

Facial and eyelid swelling is often noticed first thing in the morning and may ease through the day. It can reflect a kidney cause (protein leak, kidney disease), an under-active thyroid, allergies, or a local eye or skin problem. Puffiness around the eyes that is persistent, accompanied by leg swelling or foamy urine, or associated with a puffy face and dry skin and tiredness, is assessed rather than dismissed. See Facial Swelling and Eyelid Swelling.

Generalised body swelling

Generalised swelling — face, limbs and abdomen together, sometimes with breathlessness from fluid around the lungs — suggests a systemic cause such as kidney disease with heavy protein loss, heart failure, or liver disease with low protein. It is assessed promptly. See Generalised Body Swelling and Fluid Retention.

Fluid retention

“Fluid retention” is the phrase many people use for the feeling of holding water — tight rings, puffy fingers, bloating, or weight fluctuation. It overlaps with oedema but is often used for milder, intermittent symptoms. The assessment is the same: confirm whether true oedema is present, identify the pattern, and look for an underlying cause rather than attributing it to “water” alone. See Fluid Retention.

One-sided versus both-sided swelling

This distinction changes the urgency. Both-sided (bilateral) swelling usually reflects a systemic cause and is assessed in a routine timeframe unless warning features are present. One-sided (unilateral) leg swelling — especially if it comes on quickly, with pain, warmth or tenderness — raises the possibility of a deep vein clot and needs prompt assessment, as does one-sided swelling after surgery, long travel or immobilisation. See One-sided Leg Swelling and Bilateral Leg Swelling.

Common possible causes

• Dependent / venous causes — prolonged standing, venous insufficiency, varicose veins.
• Heart failure — both-legged swelling with breathlessness, worse on exertion or lying flat.
• Kidney disease — swelling with foamy urine, reduced urine output, or abnormal kidney tests; often facial puffiness.
• Liver disease — low blood protein causing swelling, often with abdominal fluid and jaundice.
• Thyroid disorders — an under-active thyroid causes puffiness and swelling.
• Medicines — calcium-channel blockers, steroids, certain painkillers, hormone therapy and others.
• Protein loss — heavy protein leak in the urine (nephrotic syndrome) or low protein from other causes.
• Local causes — a clot in a deep vein (DVT), infection (cellulitis), injury, or a blocked vein.
• Pregnancy and hormonal factors.
• Lifestyle factors — high salt intake, prolonged sitting, heat.

Medical evaluation

Your evaluation begins with a detailed history — exactly where and when the swelling appears, whether it is one-sided or both, how quickly it came on, whether it pits, whether it eases with elevation or overnight, and any breathlessness, reduced urine, weight change, fatigue or medication use. An examination follows, checking the distribution and type of swelling, blood pressure, the heart and chest, the abdomen, and the legs for signs of a clot or venous disease. Dr. Nayak then selects the tests that will genuinely clarify the cause rather than ordering a blanket panel.

Relevant blood, urine and other investigations

• Kidney function tests — serum creatinine, eGFR, blood urea and electrolytes.
• Urine routine and albumin-to-creatinine ratio (ACR) — to detect protein leak from the kidneys.
• Serum albumin and total protein, and liver function tests — to assess protein levels and liver cause.
• Complete blood count — to check for anaemia or infection.
• Thyroid function tests (TSH, free T4) — when a thyroid cause is suspected.
• Blood sugar or HbA1c — to identify diabetes as an underlying driver.
• BNP or NT-proBNP — a blood marker that helps confirm or rule out heart failure.
• Ultrasound of the abdomen — to assess the kidneys and liver and look for abdominal fluid.
• A leg ultrasound (Doppler) — when a deep vein clot is suspected in one-sided leg swelling.
• ECG and, where indicated, an echocardiogram — when a heart cause is suspected.

Management depends on the underlying cause

There is no single treatment for swelling — it is directed at the cause. Heart failure is managed with heart medication and fluid measures; kidney disease is treated to protect function and reduce protein leak; liver disease is managed for the underlying cause; a thyroid disorder is corrected; medication-related swelling is addressed by medical review and adjustment; a deep vein clot is treated with blood thinners; and venous or dependent swelling is managed with elevation, compression and lifestyle measures. Fluid tablets (diuretics) are used only when appropriate and under medical supervision — they are not a blanket remedy for “water retention” and can cause harm if used for the wrong cause.

Monitoring and follow-up

Follow-up confirms the swelling is settling and the underlying cause is controlled. For systemic causes this means periodic re-checking of the relevant tests — kidney function, urine ACR, blood pressure, heart and liver markers — alongside the symptom itself. Persistent or worsening swelling despite treatment is reviewed and referred for specialist care when appropriate.

Warning signs and when urgent medical evaluation is important

• Sudden one-sided leg swelling with pain, warmth or tenderness — possible deep vein clot; urgent.
• Swelling with breathlessness, especially on lying flat or with a dry cough — possible heart failure or fluid on the lungs; urgent.
• Rapidly progressive or generalised swelling with reduced urine output — urgent.
• Swelling with chest pain, fainting or a rapid irregular pulse — emergency.
• Swelling with drowsiness, confusion or very low urine output in known kidney disease — emergency.
• Swollen leg with redness, heat and fever — possible infection (cellulitis); urgent.

In-clinic and teleconsultation

Consultations are available both in-clinic in Bhubaneswar and over teleconsultation. Review of an abnormal report, repeat-test planning and ongoing monitoring often suit teleconsultation, while new or worsening swelling — especially one-sided leg swelling, swelling with breathlessness, or rapidly progressive swelling — is best assessed in person with examination and tests. A flat ₹500 fee applies to either format. Use any “Book an appointment” button on this page to schedule your visit.
