Shortness of Breath — When to Worry

Understanding breathlessness — and identifying what needs urgent attention.

Shortness of breath (dyspnoea) is one of the most alarming symptoms a person can experience. It has many causes — from the completely benign (deconditioning, anxiety) to the immediately life-threatening (heart attack, pulmonary embolism). This guide helps you assess how urgently your breathlessness needs medical attention.

Signs and Symptoms

✓ Breathlessness during exertion — normal in unfit individuals; may indicate heart or lung disease

✓ Breathlessness at rest — more concerning

✓ Orthopnoea — breathlessness lying flat (heart failure)

✓ Paroxysmal nocturnal dyspnoea — waking at night gasping (heart failure)

✓ Acute onset breathlessness — minutes to hours (PE, pneumothorax, acute heart failure, asthma)

✓ Gradual worsening over weeks to months (COPD, anaemia, heart failure)

✓ Breathlessness with chest pain — high concern for cardiac or PE cause

✓ Breathlessness with fever — respiratory infection, pneumonia

✓ Breathlessness during pregnancy — normal increase, but severe may indicate anaemia or PE

Risk Factors

Cardiac causes: hypertension, heart failure, coronary artery disease, arrhythmia
Respiratory causes: asthma, COPD, pneumonia, TB, pulmonary embolism
Anaemia — very common in Nigeria; significantly worsens breathlessness
Obesity — mechanical restriction and sleep apnoea
Anxiety and panic attacks — cause breathlessness directly
Recent immobility, surgery, or long-distance travel — pulmonary embolism risk
Pregnancy — PE risk and anaemia
Thyrotoxicosis (overactive thyroid)

When to Seek Help

NowBreathlessness at rest, breathlessness with chest pain, rapid breathing above 25/minute, oxygen saturation below 94%, blue lips or fingertips, or breathlessness following a fall or injury — emergency care immediately.

NowSudden-onset breathlessness with palpitations — possible arrhythmia or pulmonary embolism.

SoonNew or worsening breathlessness on exertion over days to weeks — needs cardiac and respiratory assessment.

RoutineGradual worsening breathlessness over months — investigation to identify cause and guide treatment.

Tests & Diagnosis

🧪 Oxygen Saturation (Pulse Oximetry)

Quick, non-invasive — below 94% is clinically significant and warrants urgent assessment.

🧪 Chest X-ray

First-line investigation — identifies pneumonia, heart failure, pneumothorax, pleural effusion.

🧪 ECG

Identifies arrhythmias, heart attack, pulmonary embolism pattern.

🧪 Full Blood Count

Anaemia — haemoglobin below 8 g/dL causes significant breathlessness on exertion.

🧪 BNP or NT-proBNP

A blood test for heart failure — elevated in heart failure, normal in breathlessness from other causes. Highly useful in distinguishing cardiac from respiratory cause.

🧪 D-Dimer and CT Pulmonary Angiogram

For suspected pulmonary embolism — D-dimer is a sensitive screening test; CTPA is the confirmatory test.

🧪 Spirometry

For suspected asthma or COPD.

🧪 Echocardiogram

Ultrasound of the heart — assesses function, valve disease, and pericardial fluid.

Treatment Options

Treat the Underlying Cause

Breathlessness management requires identifying the cause. Heart failure: diuretics, ACE inhibitors. Asthma: bronchodilators and inhaled steroids. Anaemia: iron or B12 supplementation. Pneumonia: antibiotics. PE: anticoagulation.

Supplemental Oxygen

For breathlessness with confirmed oxygen saturation below 92% — short-term emergency treatment and possibly long-term home oxygen in COPD.

Pulmonary Rehabilitation

For COPD and chronic breathlessness — significantly improves exercise capacity and reduces disability.

Anxiety and Breathing Retraining

For breathlessness driven by anxiety or panic — physiotherapy-directed breathing retraining and psychological support.

Frequently Asked Questions

Can anxiety cause breathlessness?

Yes — anxiety and panic attacks directly cause breathlessness through hyperventilation and physical tension. However, breathlessness should not be attributed to anxiety until cardiac and respiratory causes have been properly excluded.

Is breathlessness on climbing stairs normal?

Mild breathlessness on vigorous exertion can be normal in unfit individuals. Breathlessness when climbing one flight of stairs, walking on flat ground, or at rest is not normal and needs assessment.

Can anaemia cause breathlessness?

Yes — significantly. Anaemia (low haemoglobin) reduces the oxygen-carrying capacity of the blood. Breathlessness, fatigue, and pallor are the classic symptoms. Very common in Nigerian women due to heavy periods or poor dietary iron. A full blood count is the diagnostic test.

What is a pulmonary embolism?

A blood clot that travels to and blocks the pulmonary arteries (the vessels supplying the lungs). Causes sudden breathlessness, chest pain, and can be fatal. Risk factors include recent surgery, long journeys, pregnancy, and cancer. Needs immediate medical assessment.

My breathlessness gets worse lying down — what does that mean?

Breathlessness that worsens lying flat (orthopnoea) and improves sitting up is a classic symptom of heart failure — fluid accumulates in the lungs in the lying position. This symptom needs prompt cardiac assessment.
