Causes of Asthma Attack and Symptoms

The exact causes of asthma are still unknown. Firstly, genetic factors and environmental influences in the development of athma disease play a role. In addition, include allergic respiratory symptoms such as hay fever among the strongest risk factors for asthma development.

The exact interaction between genetic factors and various risk factors in the first years of life, which eventually leads to the development of asthma, but is known only in its infancy.

When asthma attack the bronchial inflammation irritated swells considerably. An increased production of tenacious mucus narrows the airways further. In addition, stretches muscles of the smaller airways (bronchi and bronchioles), together spasmodically. These processes complicate breathing, especially exhaling, and worsen the oxygenation of the body.

Asthma causes because various stimuli can trigger acute asthma attack :

• Non-specific stimuli: All asthmatics are a number of stimuli (triggering stimuli affected). These include physical exertion, cold, cigarette smoke, perfumes and air pollution.
• Specific stimuli are mainly pollen, dust, animal dander, mold and some foods. These attractions are called allergens.
• Other factors include inflammation respiratory tract, caused by viruses or bacteria, or certain pain killers (e.g. acetylsalicylic acid / aspirin).

We must distinguish between bronchial asthma disease and acute asthma attack. The symptoms of asthma depend Read more…

Allergic and Endogenous Asthma Bronchiale Description

Asthma Bronchiale Description

Asthma bronchiale (simply known as Asthma) is a chronic inflammation of airways (bronchial tubes). The mucosa reacts hypersensitive to various stimuli and swells. In addition, lung produce mucus in bronchial asthma. The consequences are recurrent attacks of breathlessness, cough and shortness of breath. Between them also longer symptom-free intervals. For more severe symptoms occur more frequently, or even courses constantly, and can lead to a significant reduction of working capacity.

In principle, a distinction is made between allergic asthma(extrinsic) and nonallergic asthma (intrinsic or endogenous).

Allergic Asthma / Extrinsic Asthma
Up to 80 percent asthma cases triggered by an allergy. The frequency of these forms asthma in children and young adults occurs. The majority of asthmatics suffer from allergic rhinitis or atopic dermatitis (eczema). Common triggers of attacks in allergic asthma have allergies to pet hair or dust mites. Rarely seizures are caused by food or medication.

Nonallergic Asthma / Endogenous Asthma
30 to 50 percent of adults have an endogenous asthma. Frequently, these individuals also polyps in the nose or sinus inflammation. Allergies are not detectable. Endogenous asthma symptoms caused by infections Read more…

Acute Bronchitis Causes and Description

Acute Bronchitis Description

Acute bronchitis is an inflammation in the larger branching airways (trachea and bronchi). Depending on which section is concerned, this is also called tracheitis, tracheobronchitis, bronchitis or bronchiolitis. Bronchitis acute usually arises in connection with a cold or flu. Acute bronchitis is usually harmless, but is often accompanied by a nagging cough.

The acute infections of the upper airways which include acute bronchitis, are the most frequent diseases. Adults suffer an average of two until three times annualy with acute bronchitis. An accumulation of these and other cold diseases are found mainly in spring and autumn. Affected are frequent children, older humans and people with immune deficiency.

Acute Bronchitis Causes

There are several pathogens that can cause acute bronchitis. These are several acute bronchitis causes :

Viruses : In about 90 percent of the cases is a cold, which is caused by viruses that can cause acute bronchitis. This spreads from the nose and throat area ( nasopharyngeal cavity ) into the deeper portions of the airways. The most common acute bronchitis virus are Adeno, Rhino, Corona, or para-influenza viruses. In children, frequent Respiratory Sinzytial (RS), ECHO or coxsackie viruses.

Bacteria : They can also cause acute bronchitis because bacteria. Often this occurs, in conjunction with or after a viral infection on (so-called secondary infection). Often there are bacteria, which increase within the cells of the human immune system and therefore can not be easily tackled, such as Chlamydia or Mycoplasma. Also bacteria like Haemophilus influenzae, which can cause meningitis in children, and pathogens such as pneumococcal pneumonia may be responsible for bronchitis causes.

Mushrooms : They are less often lead to acute bronchitis (e.g. Soorbronchitis by Candida albicans). Especially immunocompromised people (e.g. HIV-infected people) are affected with cancer. Even diseases such as whooping cough, measles, brucellosis or typhoid fever can be causes of acute bronchitis.

Irritants : Constant exposure to irritants such as vapors, gases and dust around the workplace or the particulate pollution in busy streets favor the development of acute bronchitis causes. Rarely they can even damage to the mucosa and cause inflammation of Trachealbaums.

Important is the differentiation from allergic asthma : While concentrated in acute bronchitis, the airways are restricted by inflammatory cells and mucus, they over-react to various stimuli in asthma, it comes to a sudden constriction and asthma attack.

Favouring factors  for respiratory tract infections system are:

• Cigarette smoke from smokers
• Cold water or wet weather
• Air pollution
