- Swelling in the legs, ankles, or feet (peripheral edema) is often attributed to standing too long or minor injuries, but it can be a sign of underlying heart disease.
- Heart-related swelling is commonly associated with heart failure, arrhythmias, or valve disease, and may appear with fatigue, shortness of breath, or rapid weight gain.
- Ignoring persistent swelling can allow heart conditions to progress undetected, increasing the risk of complications.

🫀 Understanding Swelling (Edema) in the Lower Extremities
Swelling in the legs or feet occurs when fluid accumulates in tissues, leading to puffiness, tightness, or heaviness. Mild, temporary swelling after prolonged standing is common, but persistent or worsening swelling may indicate a medical condition.
Patients often notice:
- Swelling that worsens during the day and improves after resting with legs elevated
- Tight shoes or rings
- Shiny, stretched skin
- Swelling that is symmetrical (both legs) or accompanied by other symptoms
While multiple factors can cause swelling, heart-related edema should never be ignored.
❤️ Heart-Related Causes of Leg and Foot Swelling
1. Heart Failure
When the heart cannot pump blood efficiently, fluid backs up into the lungs, legs, and feet. This may also cause:
- Shortness of breath
- Fatigue
- Rapid weight gain due to fluid retention
Heart failure-related swelling is usually progressive, requiring prompt attention.
2. Arrhythmias
Irregular heartbeats can reduce cardiac output, leading to fluid buildup in extremities, especially if associated with heart failure.
3. Valve Disease
Damaged heart valves can increase pressure in the heart chambers, causing swelling in the legs, ankles, or abdomen.
4. Other Cardiac Conditions
Conditions such as cardiomyopathy or congenital defects may also cause peripheral edema.
🔍 Non-Heart Causes of Swelling
While heart disease is a major cause, other potential contributors include:
- Prolonged standing or sitting
- Obesity
- Kidney or liver disease
- Medications such as calcium channel blockers or steroids
- Injuries, infections, or blood clots in the leg
Because multiple causes exist, accurate evaluation by a cardiologist is essential.
🚨 Warning Signs That Swelling May Be Heart-Related
Seek medical attention if swelling is accompanied by:
- Shortness of breath, especially when lying flat
- Fatigue or weakness
- Rapid or unexplained weight gain
- Chest pain or palpitations
- Swelling in both legs or generalized body swelling
Prompt evaluation can prevent complications such as worsening heart failure or fluid accumulation in the lungs.
🩺 How Dr. Malhotra Evaluates Swelling
Dr. Malhotra takes a comprehensive, patient-centered approach to determine the cause of swelling:
- Medical History & Physical Exam
Reviewing symptom patterns, medications, lifestyle, and risk factors. - Blood Tests
Assess kidney and liver function, electrolyte levels, and markers of heart stress. - Echocardiogram
Evaluates heart structure, valve function, and pumping efficiency. - Electrocardiogram (ECG)
Detects arrhythmias that may contribute to fluid buildup. - Chest X-ray or Imaging
Checks for fluid in the lungs or other signs of heart failure. - Monitoring & Follow-Up
Tracks response to treatment, medications, and lifestyle adjustments.
🌆 Swelling Awareness in Brampton, Mississauga, and Milton
Many patients in these areas assume leg swelling is minor, caused by long workdays, standing, or aging. However, persistent edema can be an early sign of serious heart conditions. Early evaluation by a cardiologist can:
- Detect heart failure or valve disease before it worsens
- Identify arrhythmias that may increase risk of stroke or hospitalization
- Improve quality of life through medications, lifestyle guidance, and personalized care
Dr. Malhotra emphasizes early detection and proactive treatment, ensuring patients regain comfort and prevent long-term complications.
💡 Self-Monitoring Tips
Before your cardiology consultation:
- Track when swelling occurs and how severe it is
- Note any associated symptoms (shortness of breath, fatigue, palpitations)
- Record changes in weight, especially rapid increases
- Document medications and supplements, as some can contribute to fluid retention
These details help Dr. Malhotra provide a precise and individualized evaluation.
✨ Conclusion
Swelling in the legs or feet is not always benign. While lifestyle factors may contribute, persistent or worsening swelling may indicate heart disease.
Patients in Brampton, Mississauga, and Milton experiencing leg or foot edema should schedule a consultation with Dr. Sunny Malhotra, who provides expert assessment, advanced diagnostics, and personalized treatment to protect heart health and improve quality of life.
❓ Frequently Asked Questions
Q: Can leg swelling be a sign of heart failure?
A: Yes, especially when swelling is accompanied by fatigue, shortness of breath, or rapid weight gain.
Q: Are both legs usually swollen in heart-related edema?
A: Often, yes. Heart-related edema usually affects both legs, while injury or clot-related swelling may be one-sided.
Q: What tests can determine if swelling is heart-related?
A: Blood tests, echocardiogram, ECG, and imaging can identify cardiac causes of edema.
Q: Can lifestyle changes improve heart-related swelling?
A: Yes. Elevating legs, reducing salt intake, regular activity, and medication adherence can help.
Q: When should I see a doctor immediately for swelling?
A: If swelling comes with sudden shortness of breath, chest pain, or dizziness, seek emergency care immediately.
