Shortness of breath and fatigue can signal serious heart or lung conditions.
Common causes include heart failure, coronary artery disease, anemia, lung disease, and sleep apnea.
Warning signs include breathlessness with activity or at rest, waking up gasping at night, and swelling in the legs.
A cardiologist can diagnose the cause with ECG, echocardiogram, stress test, and blood work.
Dr. Sunny Malhotra offers evaluations in Brampton, Mississauga, and Milton to prevent complications.

Introduction
Feeling tired all the time or getting winded after climbing just a few stairs is not something to ignore. Many patients in Brampton, Mississauga, and Milton dismiss fatigue and shortness of breath as part of aging, but these symptoms can signal an underlying heart problem. As a cardiologist, I often see patients who delay care, only to discover conditions like heart failure or coronary artery disease that could have been managed earlier.
This blog will help you understand the most common causes of shortness of breath and fatigue, when to seek urgent medical help, and how a cardiologist can get you back on track to better health.
Why Do Shortness of Breath and Fatigue Happen?
1. Heart-Related Causes
Heart Failure: The heart cannot pump blood effectively, causing fluid buildup in the lungs and legs. Patients often feel breathless when lying flat or wake up at night gasping for air.
Coronary Artery Disease (CAD): Narrowed arteries reduce blood flow, leading to fatigue and breathlessness during activity.
Arrhythmias: Irregular heart rhythms reduce the heart’s pumping efficiency, causing dizziness, palpitations, and weakness.
Valve Disease: Leaky or narrowed valves strain the heart and limit oxygen delivery.
2. Non-Heart Causes
Anemia: Low red blood cells mean less oxygen reaches your body, leaving you weak and breathless.
Lung Diseases: COPD, asthma, or pulmonary fibrosis can cause difficulty breathing.
Obesity and Deconditioning: Lack of exercise or excess weight reduces stamina.
Sleep Apnea: Breathing pauses at night lower oxygen levels, causing daytime fatigue.
Red Flag Symptoms That Need Immediate Attention
Seek urgent care if you experience:
Sudden shortness of breath at rest.
Chest pain with breathlessness.
Waking up gasping for air at night.
Severe fatigue with palpitations or dizziness.
Swelling in the legs and ankles.
These can be signs of heart attack, severe heart failure, or dangerous arrhythmias.
How a Cardiologist in Brampton, Mississauga, and Milton Can Help
At Dr. Sunny Malhotra’s cardiology clinics, patients undergo targeted testing to identify the root cause:
Electrocardiogram (ECG): Detects rhythm problems.
Echocardiogram: Assesses heart pumping and valve function.
Stress Test: Evaluates blood flow under exertion.
Blood Work: Screens for anemia, thyroid disease, diabetes, and cholesterol.
Sleep Study Referral: If sleep apnea is suspected.
With convenient locations in Brampton, Mississauga, and Milton, patients can access expert care without long wait times.
Treatment and Lifestyle Management
Once the cause is identified, treatment may include:
Medications for heart failure, blood pressure, or rhythm control.
Lifestyle changes: Heart-healthy diet, regular exercise, weight management.
Procedures or interventions: Stents, pacemakers, or valve treatments if needed.
Monitoring: Regular check-ups to track improvement.
Early diagnosis and treatment often reverse symptoms and prevent progression to serious disease.
