breathlessness

Breathlessness, or shortness of breath, is the sensation of not getting enough air or difficulty breathing. It can occur suddenly or develop gradually and may be caused by various factors such as lung or heart conditions, anxiety, or physical exertion. It happens when your body requires more oxygen or your lungs and heart can't deliver it effectively. While occasional mild breathlessness during exercise is normal, persistent or severe symptoms should be evaluated by a healthcare professional to identify and treat the underlying cause.
