Asthma is a chronic disease in which breathing becomes difficult due to a tightening of the bronchial tubes. Exercise-induced asthma and allergic asthma are the two most common types. Doctors say asthma usually first manifests in toddlers through wheezing and coughing fits, though these symptoms are not necessarily a surefire sign of asthma in a young child. Asthma sufferers tend to be genetically predisposed toward the disease — kids with asthma often have parents with asthma. However over the last decades asthma rates have increased in numbers that suggest environmental factors such as pollution, secondhand smoke, mould and dust can cause or aggravate asthma. These are also factors that tend to trigger asthma attacks in those who already have asthma. There is a whole flora of theories on other possible causes of asthma; one British study speculates that household chemicals like bleach and air-freshener may be to blame for the surge in asthma rates among kids; another study looks at the possibility some cases may be linked to early childhood intake of antibiotics. Whatever causes the onset of asthma, it is manageable with medication and control of triggers in the environment.

“Asthma”
"The first step in learning about asthma is to understand what asthma is, how it affects the lungs, what the major symptoms are, and what the different types are. Asthma is basically the tendency for a person’s small airways, called bronchi, within the lungs to constrict or narrow in response to a variety of stimuli. This causes difficulty breathing, coughing, or wheezing. A child needs to display this tendency on numerous occasions before the diagnosis of asthma can be made. A child who wheezes during a cold and couple times a year shouldn’t be labeled ‘asthmatic.’" …read the full article

"If the wheezing frequently recurs ask for your GP’s opinion. In a child less than a year old, the airways are so small that they can make a wheezing sound which is not true asthma. Wheezing can be quite common in early childhood, and unless the attacks persist past the age of three, most doctors say there’s no cause for alarm. " …read the full article
