Why Am I Short of Breath? Causes, Symptoms & When to Worry
Shortness of breath, also known as dyspnea, is a common symptom that can affect people of all ages. While it can be temporary and harmless, it may also be an early sign of a serious medical condition.
Shortness of breath can feel like tightness in the chest, difficulty taking a deep breath, or the sensation of not getting enough air. Some people experience it only during physical activity, while others notice it even at rest.
Common causes include asthma, chronic obstructive pulmonary disease (COPD), respiratory infections, heart conditions, anxiety, obesity, and sleep-related breathing disorders such as sleep apnea. Environmental factors like poor air quality and smoking can also worsen symptoms.
You should seek medical evaluation if shortness of breath appears suddenly, worsens over time, occurs at rest, or is accompanied by chest pain, dizziness, fainting, or nighttime breathing difficulties. These symptoms may indicate a more serious condition that requires prompt care.
A pulmonologist can help identify the underlying cause through breathing tests, imaging studies, oxygen level monitoring, and sleep evaluations. Early diagnosis allows for more effective treatment and better long-term outcomes.
