What the cause of asthma?

Answer 1

Asthma is a condition in which the airway becomes blocked, leading to wheezing, and it is difficult to breathe. Millions of people suffer from the disease and require treatment and medications to keep it under control so that they can breathe normally. There are two different types of asthma allergic and non-allergic. While you can work toward keeping the condition under control, there is no cure for asthma. There is often a question as to what exactly causes asthma.

Asthma is a condition that is genetic and generally appears in individuals who have family members who have it. In most cases, people who suffer from asthma come from families who suffer from Allergies. Essentially, an asthma attack comes about as a result of what is known as a trigger. A trigger is a substance that causes a reaction in individuals who have sensitive airway systems, which in turn causes wheezing and difficulty in breathing.

As previously stated, allergies are a key reason for individuals developing asthma. Many people with asthma developed it as children, while others had no asthmatic symptoms until adulthood. Substances that cause allergic reactions can trigger an asthma attack, such as pollen, mold, dust mites, animal dander and certain foods if the person has food allergies.

Another cause of asthma is an irritant that is present in the air. One of these in particular that can certainly lead to the development in asthma is cigarette smoke. There are harmful chemicals in cigarettes that can damage the airways of individuals not only smoking them but that of those around them, especially children. This is largely why kids who are exposed to cigarette smoke end up having respiratory problems, including asthma.

Asthma can also be caused by an illness that affects the respiratory system, such as a cold or the flu. Certain infections that affect the respiratory system can also be triggers of asthma symptoms, such as a throat infection, sinusitis, tonsillitis and bronchitis.

Certain activities can also lead to asthma because they lead to irregular breathing. Exercise induced asthma is caused by activities such as running or jogging and you are breathing heavier due to the vigor and physicality of your movements.

The weather can also cause asthma. Very dry conditions and especially bitterly cold air can lead to wheezing and an asthma attack. Often, this occurs because it is more difficult to breathe or because you feel the need to breathe primarily or fully through the mouth.

Stress can even cause asthma. When your mind is under stress, it takes a toll on your body as well.

Hi,

Allergic or extrinsic asthma is the most common type of asthma and results from breathing in certain allergens and irritants that cause an allergic reaction and asthma attack. Allergic asthma can affect anyone at any age, but children are more likely to suffer from this inflammatory condition. Researchers believe that both hereditary and environmental factors are responsible for allergic asthma.

In people with allergic asthma, the over-sensitive airway passages to the lungs become inflamed and the surrounding muscles constrict (tighten) when an allergen or irritant is inhaled. This in turn triggers asthma symptoms.

Allergic asthma is caused by inhaling specific allergens and irritants that set off an allergic reaction and asthma symptoms. In people without asthma, these allergens and irritants are often harmless and cause no response; however, in people with allergic asthma, their hyper-sensitive immune systems think that they are harmful substances.

Allergens that can trigger asthma attacks:

• Tree, grass and weed pollen.
• Mould spores.
• Animal dander (skin flakes). Pet urine, faeces, saliva and hair can also trigger an asthma attack.
• Cockroach faeces and saliva.
• Dust mite faeces.

Irritants that can trigger asthma attacks:

• Tobacco smoke and smoke from candles, incense or a chimney.
• Cold air.
• Air pollution.
• Scents from scented products, such as perfumes, air fresheners and lotions.
• Dust.
• Industrial and household chemicals.

Answer 3

It is something that you are born with and doesn't really have a cause.

Answer 4

its a genetic disorder...or can be caused by smoking/2nd hand smoking

Answer 5

Genetic and environmental factors cause asthma. Pollen and dust are environmental factors that cause allergic reactions such as asthma.

Answer 6

Causes of asthma can string to genetics and the environment. Some environment factors that cause asthma are mold, dust, pollen and smoke.
