Asthma is a disease that can happen to anyone and can occur all ages, however, asthma is generally more common in children aged under five years old and adults at the age of thirty years.

Prof. Dr.. Dr. Heru Sundaru, Sp.PD, KAI FKUI University of Indonesia said, “cases of asthma in children in Indonesia a little higher than adults. Then asthma in children will lose some, and will appear again as an adult because the natural way “.

Asthma experts believe that asthma is a hereditary disease and most people who suffer from asthma due to allergy to a particular source of allergies (allergens). Allergens is a factor that comes from the environment.

Asthma Causes

The term cause of asthma is less accurate because until now the cause of asthma is unknown. There have been many studies conducted by experts in the field of asthma to explain the causes of asthma, but none theory or hypothesis can be accepted or agreed by all the experts.

Nevertheless a clear airway with asthma have a unique trait that is highly sensitive to various stimuli (bronchial hyperreactivity = hipereaktivitas airways). Cigarette smoke, mental stress, allergens in a normal person does not cause asthma but with asthma in this stimulation may cause an attack.

In asthma, constriction of the airways is a response to stimuli in the normal lung will not affect the respiratory tract. This narrowing can be triggered by various stimuli, such as pollen, dust, animal fur, smoke, cold air and exercise.

In an asthma attack, smooth muscle spasm of the bronchi and networking experience that covers the airways have swollen because of inflammation and the release of mucus into the airways.

This will reduce the diameter of the airways (called bronchoconstriction) and this causes narrowing of the patient must be trying hard in order to breathe.

Certain cells in the airways (particularly mast cells) allegedly responsible for the beginning of this constriction. Mast cells throughout the bronchi substances such as histamine release and causing leukotrien:

* Smooth muscle contraction
* Increased mucus formation
* Transfer of certain white blood cells into the bronchi.

Mast cell material is issued in response to something they know as a foreign object (allergens), such as pollen, fine dust contained in the home or animal fur.

But asthma can also occur in some people without a specific allergy. The same reaction occurs when the person is doing sports or being in the weather dingin.Stres and anxiety can also trigger the release of histamine and leukotrien.

Other cells (eosnofil) found in the asthmatic airways release other materials (also leukotrien), which also causes constriction of the airways.

Factor triggers asthma attacks

Triggers cause respiratory tract irritation and may cause constriction of the airways (bronchoconstriction). Triggers do not cause inflammation. Many of the medical community who consider the trigger and bronchoconstriction was an acute respiratory problem, which does not mean asthma.

The symptoms and bronchoconstriction caused by triggers occur immediately, place in a short time and more easily overcome in a short time. However, respiratory tract will react more quickly if it appears or there is inflammation.

1. Factor in patients
* Genetic Aspects
* Possible allergies
* Channels are breathing easily aroused
* Gender
* Race / ethnicity
2. Environmental factors
* The material in the room:
o house dust mites
o Animals, cockroaches
* The material in the outer room:
o Wheat flower
o Mushrooms
* Certain foods, preservatives, flavorings, food coloring
* Certain medicines
* Irritant (perfume, stimulating smells, household spray)
* Excessive emotional expression
* Cigarette smoke from active smokers and passive
* Air pollution from the outside and the room
* Respiratory tract infection
* Exercise induced asthma, those who relapse asthma when specific physical activity
* Change weather
