Causes Of Asthma online quotes guidelines

Causes of asthma and Symptoms of asthma vary from person to person and also in intensity in the same person from time to time. The important feature is the oscillation (variation) in airflow obstruction which occurs over short periods of time. This can be recorded by using ‘flow meters’ twice or thrice a day. This variation in airflow will be present even when the patient has no clinical symptom or discomfort.


  • Shortness of breath.
  • Wheeze off and on worse on forcefully breathing out,relieved on using asthma inhalers (Salbutamol).
  • Dry cough nocturnal cough in children.
  • Chest tightness.

Quotes guide  factors precipitating attacks of asthma

  • Allergens (house dust, pollen, dander of pet animals).
  • Irritants (smoke, dust, strong smells, fumes).
  • Exercise, cold air, excessive laughter, emotional stress, change in climate.
  • Infection (specially viral) of nose, throat and chest.
  • Occupational exposure (chemicals, dyes, detergents, etc.).
  • Drugs (beta blockers such as Atenolol pain-killers such as Aspirin, Ibuprofen, etc.).
  • Food additives (meta sulphide).
  • Menstruation, pregnancy, thyroid disease.


  • Widespread wheezing (bronchi) audible on auscultation.
  • Over inflated chest leading to deformity in children (pigeon chest).
  • Nasal polyp, eczema, urticaria.

While the description of the symptoms of asthma and the possible limitations that result from these symptoms are clear,
of the asthmatic function differently from that of normal lungs, but what are the underlying causes?

It had been a long-standing theory that allergens are suspected of being the sole culprits, or “triggers” in the asthmatic condition for causes of asthma. Although allergies play a definite role for some asthmatics, it is not the underlying cause we are searching for. In the asthmatic, there is an imbalance in several of the biochemical systems involved in proper lung functioning. This stems from a dysfunction of the automatic nervous system. All asthmatics have this dysfunction that is the basis for their programmed abnormal lung reaction. This chemical malfunction, then sets up the lungs for cellular-level interactions that are also abnormal and that interrupt smooth muscle functioning.

So,the asthmatic individual appears to be programmed to react abnormal y to certain stimuli. These stimuli serve as “triggers. A trigger is anything that initiates the production of mediators that, in turn, result in abnormal, harmful reaction!: (spasms, swelling, and mucus production). Francis Racker’smann, a prominent pioneer in allergy research in the 1920s, was instrumental in discovering the various triggers that precipitate  an asthma attack. Rackermann used the term trigger, and elaborated the analogy to a gun. He felt that while it is very important to know what pulls the trigger in an asthma reaction, to really understand the disease you also needed to know how the gun is loaded. This eluded him and has been unclear until recently.

We now know that the ammunition appears to come from biochemical imbalance in the autonomic nervous system, of genetic origin, which affects proper lung functioning. Once the gun is loaded, it can go off as soon as one pulls the trigger. The lungs of the asthmatic are like the fingers of a trigger happy gun fighter. They are very vulnerable, sensitive, and quick to react in an exaggerated way.let us discuss the triggers in next post.
