FAQ
Can anxiety cause shortness of breath?
Yes. Stress and panic attacks can trigger fast, shallow breathing. Slowing down with pursed-lip breathing often helps.
How do I know if it’s asthma or heart-related?
Asthma often includes wheezing, coughing, or chest tightness. Heart-related breathlessness may come with ankle swelling, chest pain, or unusual fatigue. Only a clinical exam can confirm.
What tests will a doctor do?
Depending on symptoms: chest X-ray, ECG, spirometry (lung function), and blood tests for oxygen level or anemia.
Bottom Line
Mild breathlessness after exercise or sinus congestion often improves with simple remedies. But sudden, severe, or ongoing shortness of breath can be a sign of serious heart or lung disease — don’t ignore it.
