Asthma is a chronic respiratory disease characterized by airway inflammation, constriction, and excessive mucus production, leading to difficulty in breathing. The exact cause of asthma is not fully understood, but it is believed to be due to a combination of genetic and environmental factors such as allergens, air pollution, and respiratory infections. Risk factors for developing asthma include a family history of asthma or allergies, exposure to tobacco smoke, and obesity. Asthma can be managed through proper medication and avoiding triggers.
