The most common causes of asthma is environmental pollution. Exposure to the environment of cotton and flour dust, smoke, smoke, and a wide range of chemicals further increases the risk of asthma.
However, it is believed by some to be partially inherited. People think that there is a connection between genetic makeup and disease. There isn’t – it only makes one more susceptible. But it is also considered to be due to a wide array of other factors, such as environmental, infectious, and chemical factors. Therefore, although there is no definitive cause as of yet for asthma, there are certain presumed factors both in regards to the cause of asthma as well as to the onset of asthma attacks.
Many people that have Asthma, may have an individual and/or family history of allergies. Allergy testing may be helpful in identifying allergens, but in sensitive individuals, asthma symptoms can be triggered by:
- Inhaled allergens (allergy triggers), such as pet hair, dust mites, moulds or pollens, animal protein, cockroaches, and certain foods
- Respiratory infections and sinusitis
- Irritants, such as strong perfumes
- Chemicals such as coal or talcum powder
- Air pollutants
- Changing weather conditions
- Sensitivity to medications, such as aspirin or sulfites which are used as preservatives in foods and beverages;
- Gastroesophageal reflux
- Emotional anxiety
- Nervous stress
Patients with delayed pattern food allergy have the most persistent inflammatory form of chronic asthma. Those who have a nasal allergy often have asthma that may be triggered by it.
