Results for: Shortness of Breath
Emergency Warning Signs
Call 911 or go to the emergency room immediately if you experience:
- Difficulty breathing or shortness of breath
- Chest pain or pressure
- Sudden numbness or weakness in face, arm, or leg
- Sudden confusion or trouble speaking
- Severe allergic reaction (swelling, difficulty swallowing)
- Heavy bleeding that won't stop
- Loss of consciousness
- Signs of stroke (face drooping, arm weakness, speech difficulty)
20 Possible Conditions
These conditions are listed by likelihood based on the symptom. This is not a diagnosis.
Asthma
A chronic inflammatory airway disease that causes reversible airway narrowing and wheezing.
Chronic Obstructive Pulmonary Disease (COPD)
Progressive lung disease, usually due to smoking, that obstructs airflow and reduces oxygen exchange.
Pneumonia
Infection of the lung parenchyma that fills alveoli with fluid, leading to impaired breathing.
Congestive Heart Failure
The heart's inability to pump efficiently, causing fluid buildup in the lungs and shortness of breath.
Pulmonary Embolism
A blood clot lodged in a pulmonary artery that blocks blood flow and oxygen delivery.
Anxiety / Panic Attack
Acute episodes of intense fear that can cause rapid breathing and a sensation of breathlessness.
Anemia
Reduced red blood cell count limits oxygen transport, leading to fatigue and dyspnea on exertion.
Interstitial Lung Disease
A group of disorders causing scarring of lung tissue, which stiffens the lungs and impairs gas exchange.
Upper Respiratory Infection (Common Cold)
Viral infection of the nasal passages and throat that can cause mild shortness of breath, especially with congestion.
COVID-19 Infection
SARS‑CoV‑2 infection can cause viral pneumonia and acute respiratory distress, leading to dyspnea.
Lung Cancer
Malignant growth in lung tissue that can obstruct airways or cause pleural effusion, producing breathlessness.
Pneumothorax
Air leaks into the pleural space, collapsing the lung and causing sudden, sharp shortness of breath.
Pulmonary Hypertension
Elevated pressure in the pulmonary arteries strains the right heart and reduces oxygenation.
Obesity Hypoventilation Syndrome
Excess body weight impairs chest wall mechanics, leading to chronic low‑level hypoventilation.
Acute Bronchitis
Inflammation of the bronchial tubes, often viral, that produces cough and mild to moderate dyspnea.
Myocardial Infarction (Heart Attack)
Blockage of coronary arteries can cause chest pain and acute shortness of breath due to heart dysfunction.
Sarcoidosis
Granulomatous disease that may involve the lungs, causing stiffness and reduced lung capacity.
Pleural Effusion
Accumulation of fluid in the pleural space compresses the lung and limits expansion.
Chronic Kidney Disease (Fluid Overload)
Impaired kidney function can lead to fluid retention, causing pulmonary congestion and dyspnea.
Allergic Rhinitis (Post‑nasal Drip)
Allergy‑induced nasal inflammation can cause mucus drainage that irritates the airway and triggers mild breathlessness.
When to Seek Emergency Care
While many conditions can be managed with home care or a doctor's visit, some situations require immediate medical attention. Seek emergency care if:
Heart-Related
Chest pain, rapid heartbeat, or shortness of breath
Brain-Related
Severe headache, confusion, or sudden vision changes
High Fever
Fever above 103°F (39.4°C) or fever with stiff neck
Severe Bleeding
Uncontrolled bleeding or coughing up blood
