Breathlessness, medically referred to as dyspnoea, is a sensation of difficulty or discomfort in breathing. It can be caused by various underlying medical conditions or factors. Understanding the causes and symptoms of breathlessness is crucial for proper diagnosis and management.


  • Respiratory Conditions: Respiratory illnesses such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, pulmonary fibrosis, and bronchitis can lead to breathlessness.
  • Cardiovascular Disorders: Heart-related conditions like heart failure, coronary artery disease, and arrhythmias can result in inadequate oxygen supply to the body, leading to breathlessness.
  • Anemia: Low levels of red blood cells or hemoglobin in the blood can reduce the oxygen-carrying capacity, causing breathlessness.
  • Obesity: Excessive body weight can put pressure on the chest and lungs, making it difficult to breathe properly.
  • Physical Deconditioning: Lack of physical activity or prolonged bed rest can weaken the muscles involved in breathing, resulting in breathlessness.
  • Anxiety and Stress: Emotional factors such as anxiety and panic attacks can trigger shortness of breath.
  • Environmental Factors: Exposure to pollutants, allergens, smoke, or high altitudes can induce breathlessness in susceptible individuals.


  • Shortness of Breath:Feeling unable to take a deep breath or feeling like you can’t get enough air.
  • Rapid Breathing: Breathing faster than usual, even at rest.
  • Chest Tightness: Sensation of pressure or tightness in the chest, making it difficult to expand the lungs fully.
  • Wheezing: High-pitched whistling sounds during breathing, often associated with asthma or COPD.
  • Coughing: Persistent coughing, particularly with sputum production, may accompany breathlessness in conditions like pneumonia or bronchitis.
  • Fatigue: Feeling excessively tired or exhausted, especially after minimal exertion due to inadequate oxygen supply.
  • Dizziness or Lightheadedness: Feeling faint or dizzy, which can be a sign of decreased oxygen levels in the blood.
  • Cyanosis: Bluish discoloration of the lips, fingertips, or skin due to insufficient oxygenation.


Breathlessness can be a distressing symptom with various potential causes, ranging from respiratory and cardiovascular conditions to emotional and environmental factors. It’s essential to seek medical evaluation if you experience persistent or severe breathlessness, as it may indicate an underlying health issue that requires treatment. Early diagnosis and appropriate management can help improve quality of life and prevent complications associated with breathlessness.
