Asthma


Asthma is a reaction, usually allergic, characterized by attacks of wheezing and difficult breathing, particularly exhaling. Asthma attacks are brought on by muscular spasm of the passages conveying air to and within the lungs (bronchi). The mucus membranes that line the respiratory passageways may become irritated and secrete massive amounts of mucus which narrows the airways and worsens the asthma attack.

Most asthmatics have allergies to foods, especially milk, food additives or airborne substances such as dust, pollen and moulds.
