Asthma Among Kids

Nearly 45 per cent of the surveyed children from 1-4 years age group are likely to have asthma, as they were dependent on bottle feeding instead of mother's milk. Similarly, 32 per cent from 5-9 years had chronic or recurrent symptoms of asthma either due to parental smoking or family history.
Notedly, these children generally suffer from nocturnal cough, shortness of breath, chest tightness and heartburn. In case of asthma, due to inflammation of the walls which is triggered by the irritants, the thickness of the walls decreases which results in a smaller passageway for air to flow through. The inflamed tissues produce an excess amount of sticky mucus into the tubes which clump together and block the smaller airways. Therefore, during an asthma attack the muscles tighten, constricting the passage of airways.
Besides, particulate matter, asthma can be triggered due to pollen grains, dust, mites, pets, insects, foods such as fish, egg, peanuts, cows milk and additives as well.
Dr Singh said: "Shortness of breath, especially with exertion, wheezing, whistling or hissing sound when breathing out, chronic coughing usually at night and early morning are the main symptoms which may occur after exercise or when exposed to cold and dry air."
He suggested that the asthmatic children to take extra care and avoid things to which they are allergic. "Precautionary measures should be taken in case of children. Exposure to cold and dry air should be avoided. Inhalers should be used in case of an attack," he added.

Causes and Risk Factors of Asthma in Children

There is a strong hereditary factor associated with the disease. Patients and their family may have a history of asthma, a topic dermatitis , and allergic rhinitis. In fact, a number of studies have shown that a majority of children who develop asthma have allergies as a trigger for the asthma. Often a child develops eczema, then develops allergic nasal symptoms and then asthma. This progression has been termed the "allergic march". The two main factors that contribute to asthma are inflammation of the airway passages and hyper reactive bronchi.

For most kids, breathing is simple: They breathe in through their noses or mouths and the air goes into the windpipe. From there, it travels through the airways and into the lungs. But for kids with asthma, breathing can be a lot more difficult because their airways are very sensitive.

An asthma flare up, which some people call an asthma attack or episode, happens when a person's airways get swollen and narrower and it becomes a lot harder for air to get in and out of the lungs. Sometimes the swollen airways produce extra mucus, which makes things pretty sticky, so it's easy to see why it's hard to breathe

In between flare-ups, a kid's breathing can be totally normal or seem that way. But during a flare-up, it can feel like the person is breathing through a straw. A kid with asthma may wheeze cough, and feel tightness in the chest.
