What Is Allergy? Why Does Allergy Cause Asthma?

Asthma is a condition when the airways are inflamed leading to construction of the air passage. It is usually a chronic disease, and comes with acute exacerbation when being exposed to triggering factors.

Asthma generally affects people of all ages. It presents with wheezing and shortness of breadth accompanied by coughing. Asthma has a very close relation to allergy. As a matter of fact, it would not be wrong to say that the two go hand in hand.

Not all patients who are allergic may have asthma. Allergy means simple hypersensitivity. Allergy can be explained as the hypersensitive reaction of our body to any cause, or allergen. Have you ever wondered why you are allergic to certain things in the first place?

Allergy is an immune response of our body. Normally it is a response to a very harmless substance like pollen or dust that triggers the reaction. The exposure of these factors sets onset of reaction within our blood to release histamine. Thus the release of histamine contributes to symptoms like inflammatory reaction and even constriction of the smooth muscles of the lungs. Inflammatory reaction causes swelling, and constriction causes narrowing. Can you escape asthma attack in the given pathological circumstances?

With the airways constricted due to the, the passage of is restricted, both in and out of the lungs. Asthma patients present with the following symptoms-

  • Wheezing- this is a squeaky and whistling sound that is heard during breathing, since the airway is narrow.
  • Dyspnoea- (Also Spelt as Dyspnea) – shortness of breath, or difficulty in breathing.
  • Tightness in Chest
  • Coughing- occasionally accompanied with mucous secretion in the chest and so expectoration too.

Sometimes, just keeping away from these allergies and its causative factor, a nebulizing and minimal medication helps resolve this temporary attack. When the attack is graver, hospitalization is better.
