Asthma

Asthmatic bronchus (asthma) is a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing. An asthma attack may include coughing, chest tightness, wheezing, and trouble breathing. The attack happens in your body’s airways, which are the paths that carry air to your lungs. As the air moves through your lungs, the airways become smaller, like the branches of a tree are smaller than the tree trunk. During an asthma attack, the sides of the airways in your lungs swell and the airways shrink. Less air gets in and out of your lungs, and mucous that your body makes clogs up the airways even more. It usually results from an allergic reaction or other forms of hypersensitivity. Affecting patients of all ages, symptoms of asthma include wheezing, chest tightness, difficulty breathing and coughing. From nebulizer machines and humidifiers, to asthma allergy medications.
