Severe asthma is a serious form of asthma that significantly affects a person's ability to breathe. It is characterized by frequent and intense asthma attacks, which can lead to symptoms like wheezing, shortness of breath, and chest tightness. People with severe asthma often require high doses of medication and may still experience symptoms despite treatment. This condition can be triggered by various factors, including allergens, air pollution, and respiratory infections. Severe asthma can limit daily activities and may require emergency medical attention. Proper management and regular check-ups with a healthcare provider are essential for controlling symptoms and improving quality of life.
