Difficulty Breathing: Causes, Warning Signs & When to Act

What Is Difficulty Breathing?

Difficulty breathing is the sensation that you cannot breathe deeply enough or get sufficient air. It can come on suddenly or develop gradually. While exercise-induced breathlessness is normal, difficulty breathing at rest or during routine activities is not and should be evaluated.

Common Causes of Difficulty Breathing

• Asthma attack
• Anxiety or panic
• Allergic reaction
• Pneumonia
• Heart failure
• COPD exacerbation

When to See a Doctor

See a doctor for any new or worsening difficulty breathing. Call 911 immediately if breathing difficulty is sudden and severe, comes with chest pain, causes blue discoloration of lips or face, or if you cannot speak in complete sentences.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

What causes sudden difficulty breathing?

Sudden breathing difficulty can be caused by asthma attacks, allergic reactions, panic attacks, pneumothorax (collapsed lung), pulmonary embolism, or heart attacks. Sudden onset always requires urgent medical evaluation.

Can I have difficulty breathing from anxiety?

Yes, anxiety causes rapid, shallow breathing that makes you feel like you can't get enough air. This creates a cycle: breathing difficulty increases anxiety, which worsens breathing. Controlled breathing techniques break this cycle.

When should I call 911 for breathing problems?

Call 911 if you cannot breathe, your lips or face turn blue, you feel like you are suffocating, breathing difficulty came on suddenly, or if it is accompanied by chest pain or loss of consciousness.

What tests diagnose breathing problems?

Common tests include pulse oximetry (oxygen levels), chest X-ray, pulmonary function tests, CT scan, blood tests, and EKG. The specific tests depend on your symptoms and suspected cause.

How much does emergency breathing care cost?

An ER visit for breathing difficulty costs $1,000-$5,000 or more. A pulmonologist follow-up costs $200-$500. Ongoing asthma management costs $100-$400 monthly. OpenMyPro helps you plan affordable care.
