I've been experiencing persistent shortness of breath. What could be the cause?

1 Answer

Persistent shortness of breath can have several possible causes, and it’s important to identify the underlying issue. Some common causes include:

1. Respiratory conditions: Such as asthma, chronic obstructive pulmonary disease (COPD), pneumonia, or pulmonary fibrosis.


2. Heart conditions: Like heart failure, coronary artery disease, or arrhythmias can cause difficulty breathing.


3. Anxiety or panic attacks: These can lead to a sensation of shortness of breath, often accompanied by feelings of anxiety or stress.


4. Allergies or asthma: Both can trigger breathing difficulties, especially if you're exposed to allergens or irritants.


5. Obesity: Extra weight can put strain on the lungs, leading to shortness of breath, especially during physical activity.


6. Pulmonary embolism: A blood clot in the lungs can cause sudden shortness of breath, often accompanied by chest pain.


7. Infections: Respiratory infections, like the flu or COVID-19, can cause inflammation and difficulty breathing.



It’s important to see a healthcare provider for a proper evaluation and diagnosis, as persistent shortness of breath can be a sign of a serious condition.
