Shortness of breath – Causes and management
Shortness of breath, also called dyspnea, can be alarming, especially when it occurs suddenly and interferes with daily life. The condition’s severity can vary, depending on the cause. Also, it may come and go, or persist, leaving one tired and uneasy in either case. An effective first step to manage dyspnea—like with most health issues—is to understand its causes and symptoms. The more one understands the condition, the better they can manage it and recover. Causes of shortness of breath Physical exertion and environmental factors The body needs more oxygen when working out or performing activities like running and climbing, which can trigger shortness of breath. The problem may also occur when one spends a long time at high altitudes. Since there is less oxygen in the air at higher altitudes, the lungs and heart work harder to keep up with the demand. Lung conditions The primary function of the lungs is to take in oxygen, send it into the bloodstream, and expel carbon dioxide, a process called gas exchange. This process takes a hit when a condition affects the lungs. As a result, the body might run low on oxygen or end up with too much carbon dioxide. In either case, one might feel the need to breathe harder to balance oxygen levels, leading to what they experience as shortness of breath.
