What Causes Asthma?

Asthma is one breathing ailment that’s rampart among people. Statistics records confirmed it that about 300 million populations all over the world are affected by asthma. Among these total affected persons, USA has the highest population of about 22 million asthmatic patients. People from all range of ages can experience asthma but this problem usually originates from childhood. As of now, there are approximately 6-7 million of children in the United States suffering from asthma symptoms. Asthma causes about 255,000 deaths of the world total mortality rate each year.

What Causes Asthma?

Asthma problem is known to be one of the chronic diseases commonly for most children especially those born with low birth weight or those who are frequently endanger to cigarette smoke or rise up in poor economic environment. The symptoms of asthma generally occur in children within of 5 for the first occurrence. Asthma symptoms usually start with consistent sequence of wheezing alongside with respiratory infections. There are other possible factors such as allergies, eczema resulting from allergies or problems of hereditary.

Boys have higher risks of getting asthma to girls during their childhood. Nevertheless, this trend reversed as they approached adulthood. According to researcher’s theory, the size of the boys’ airways is invariably smaller to that of the girls, which may lead to this deviation between the males and the females. And once is contacted through viruses, due to the smaller size of the airways, the male thus results to wheezing which occur more frequently.

Here Are What May Cause Asthma

One of the following factors may be what is responsible for the cause of your asthma attack:

1. Allergies

Almost all the asthmatic patients suffer from allergies. More than 25% of these patients having rhinitis allergic can lead to asthma. In addition, antibodies present in their blood can cause allergic reactions that can further lead to the swollen of the airways. This is seen as one of the main cause of asthma. Allergens can easily be formed or dispersed indoor. Animal’s proteins, pet dander, dust mites in the house, cockroaches, fungi and others are commonly seen in the indoor. The desire to build energy conservation homes can also triggers the exposure of what causes asthma.

2. Cigarette smoke

Smoking cigarettes is not only linked with asthma incidence but as well increase death rate that is usually caused by wheezing, asthma and respiratory infections. The worse part of it, children whose parents smoke, adolescent who have started smoking already or those who are frequently exposed to second hand smoking all have higher probability of asthma risks.

3. Environmental factors

Indoor air pollution is one of the major threats to health problems. For instance, molds, toxic gases and chemicals brought about by indoor air pollutants frequently results to allergic responses and symptoms of asthma. And also people who do use gas stove in their kitchen are exposed to higher risks of symptoms of asthma such as hay fever, wheezing, breathing difficulties or asthma attacks.

It has been discover that sulfur oxide, nitrogen oxide, air pollution, ozone and cold temperatures can activate asthma problems among some set of people. And it air pollutions is severe, symptoms of asthma will be exacerbated. That is why sometimes there is high number of hospital admissions in certain period. Amongst these harmful pollutants like ozone is usually relinquished by smog which have the capacity to cause coughing, chest pain and short breathe. More so, smoggy weather is capable of releasing plenty of sulfur-dioxide into the atmosphere which can compress human airways and further leads to asthma attacks.

Changes in weather is another vital environmental factor that my cause asthma. It has been known that cold weather is able to cause constriction of the airways, secretions, congestion or drop mucociliary clearance. Humidity also acts an essential role on certain population health groups.

4. Airway hyperreactivity

even though research has not make a clear evidences of the association of airway and hyperactivity and asthma, allergies or cold air can probably induce airway hyperactivity which may results inflammation of the airways. Some may have higher % risks of asthma while some may not even if their having hyperactive airways.

5. Obesity

Adults whose body mass index (BMIs) starting from 25 – 30% has higher asthma risk. While adults having BMI of 30 plus have double chances of experiencing asthma. According to researchers, they say those with non-allergic asthma have higher asthma risks than those who have allergic asthma.

6. Stress

Stress is another considerable factor that can cause asthma because stress can aggravate asthma-associated activities such as smoking. It has also been proven by research that stress is able to modify immune system.

7. Pregnancy

Baby born by Caesarean section have higher chance of up to 20% risks to asthma occurrence to those born by normal vaginal birth. The immune baby modifying may get infected due to exposure to bacteria during Caesarean section. However, birth way can as well contribute to asthma prevalence.

Pregnant women who smoke have babies who are likely to suffer lower pulmonary function after birth and this poses risks of asthma incidence. To buttress it, research findings say premature birth can acts as risk of asthma development.

8.Atopy

One of the major causes of asthma is Atopy. Atopy is the susceptibility towards getting a certain hypersensitivity response such as atopic dermatitis (eczema), hay fever, allergic conjunctivitis.

Research findings review that 40 – 50 % of children suffering from atopic dermatitis are expose to risks of developing asthma. And they are likely to severe and persistent asthma than other adults.
