Types, Causes and Prevention of Asthma
Asthma is a disorder impacting on the airways of the lungs. Replying to certain triggers the mucous surfaces of the lungs of a patient swell up causing the bronchial tubes to go into spasm. This makes breathing complicated. The muscles may tighten up and inappropriate mucus might be produced leading to trouble breathing and panting. Unlike any other respiration conditions like protracted bronchitis and obstructive pulmonary illness, the redness due to asthma is reversible and often replies well to medicine.
There are essentially 2 kinds of asthma :
1. Intrinsic – occurring as a consequence of an infection or later in life.
2. Extrinsic – due to allergies.
Common allergens include several food types which can result in an immediate asthmatic response. These include seafood, nuts and eggs. While other foods such as wheat, chocolate and certain food coloring and additives may result in a delayed response. Asthma may also be triggered by allergy to dust mites, pollen, dust, insect sprays or other pollutants.
The degree of seriousness of asthma varies widely, with some patients suffering only occasional symptoms while others can have a continuous underlying level of redness and consequent impairment of respiring.
Signs of lingering underlying asthma include difficulty breathing during exercise, chronic cough and the repeated urge to clear the throat, tightness of chest and puffing. Exacerbation of asthma may lead to what’s generally known as an asthma attack. In this example the patient experiences trouble breathing even during rest, fast heart beat, panting and chest constriction, rhonchus or loud respiring and coughing. Depending on seriousness of the assault air intake be could be so proscribed the patient may turn blue and even lose consciousness.
Information about causes and the development of asthma is far from complete. However, studies seem to suggest that it is closely linked with the body’s immune responses. Incidence is known to vary significantly between racial groups, affluent and poorer areas of the world and also based on environmental factors etc. Studies have shown links with the following:
Exposure to tobacco smoke appears to be associated with higher incidence of asthma
Children born via caesarean section appear to have significantly higher levels of asthma than those born by vaginal delivery. It is thought that this is due to different levels of bacterial exposure during delivery and it’s impact on development of the immune system.
High levels of environmental pollutants have also been linked to higher incidence.
Stress has for some time been suspected of causing asthma. It is hypothesised that stress may affect the working of the immunological response and thus indirectly influence the incidence of asthma.
Regular exposure to antibiotics particularly at a young age as well as being raised in an intolerably hygienic environment, to explain not being exposed to the common adolescence breathing infections etc may leave the immunological response compromised and lead to larger possibility of developing asthma. On the other hand evidence implies that children who grow up in bigger families and are exposed to the common infancy sicknesses are way more resilient when it comes round to keeping asthma in check.
Treatment and control of asthma may involve several approaches encompassing lifestyle changes, medication and dietary changes and could include:
Getting shot of or reducing exposure to the trigger factors in the the environment or diet.
Giving up smoking and avoiding exposure to second hand smoke.
Reducing or dumping dairy goods from diet as dairy goods push the production of mucus.
Medicine including short term or long-term Bronchodilator might be used to handle bronchospasms associated with asthma.
Vitamin C and Cod liver oil could also be used to reduce seriousness of reactions and redness.
