Shortness of breath or covid 19
Shortness of breath or Covid 19
Most cases of shortness of breath are due to heart or lung conditions. Your heart and lungs are involved in transporting oxygen to your tissues and removing carbon dioxide, and problems with either of these processes affect your breathing.
Shortness of breath that comes on suddenly (called acute) has a limited number of causes, including:
Anaphylaxis (a severe allergic reaction)
Asthma
Carbon monoxide poisoning
Cardiac tamponade (excess fluid around the heart)
COPD (chronic obstructive pulmonary disease) exacerbation - worsening of symptoms
Coronavirus disease 2019 (COVID-19)
Heart attack
Heart arrhythmia (heart rhythm problems)
Heart failure
Pneumonia (and other pulmonary infections)
Pneumothorax (collapsed lung)
Pulmonary embolism (blood clot in an artery in the lung)
Sudden blood loss
Upper airway obstruction (blockage in the breathing passage)
In the case of shortness of breath that has lasted for weeks or longer (called chronic), the condition is most often due to:
Asthma
COPD (chronic obstructive pulmonary disease) exacerbation - worsening of symptoms
Deconditioning
Heart dysfunction
Interstitial lung disease
Obesity
Pleural effusion (accumulation of fluid around the lungs)
A number of other health conditions can also make it hard to get enough air. These include:
Lung problems
Croup (especially in young children)
Lung cancer
Pleurisy (inflammation of the membrane surrounding the lungs)
Pulmonary edema (excess fluid in the lungs)
Pulmonary fibrosis (scarred and damaged lungs)
Pulmonary hypertension
Sarcoidosis (collections of inflammatory cells in the body)
Tuberculosis
Heart problems
Cardiomyopathy (problem with the heart muscle)
Heart failure
Pericarditis (inflammation of the tissue around the heart)
Other problems
Anemia
Anxiety disorders
Broken ribs
Choking: First aid
Epiglottitis (swelling of the "lid" of your windpipe)
Foreign object inhaled: First aid
Guillain-Barre syndrome
Kyphoscoliosis (a chest wall deformity)
Myasthenia gravis (a condition causing muscle weakness)
