Respiratory symptom

Main symptoms

In respiratory symptoms, the following symptoms are mainly caused.

Cough, breathing is painful, wheezing, dyspnea, throat clogging, asthma (details will be described later)

Cough, wheezing, dyspnea are all symptoms related to asthma.

Also, there is the bronchial asthma as a typical allergic disease that includes these symptoms.

About bronchial asthma

It is caused by inflammation by the allergen invading from the mucosa of the trachea or bronchus and contraction of the wall of the trachea (smooth muscle).
Currently 5 million people are diagnosed with this disease. In addition, over 90% of patients with bronchial asthma are mite allergy. It is classified as I type.

There are mainly two types of bronchial asthma.

  • Childhood asthma
    ⇒70% of children develop asthma in infants and get better in puberty. Most are allergic (allergens that can be identified).
  • Adult asthma
    ⇒There are cases where you transition from childhood asthma or relapse after remission. 40% of adult asthmatic patients are nonallergic which can not be identified by allergens.


  • Dyspnea
  • Wheezing (noise): When you try to breathe, it sounds like "Zee zee" or "Hugh Hugh".
  • To have a cough
  • More sputum

About late reaction

It may happen again after a while asthmatic attacks have taken place.
It often occurs on dawn. It occurs when eosinophils and basophils in the body release leukotrienes that cause inflammation.

Environment that promotes bronchial asthma

Strong cough, cold air, intense exercise, air pollution, etc. will cause the bronchus to be injured. Bronchial asthma occurs by allergens entering there.


It is effective to moisturize to prevent invasion from the skin, to change carpets and beds etc. to ones that do not easily adhere to, to eliminate allergens, frequently aroused. These ways can reduce the number of asthma and reduce symptoms medicine treatment(Anti histamine used for allergic rhinitis, inhaled steroid etc.) are also available.
