Asthma is a health condition that targets the breathing airways of the bronchioles, which is located in the lungs. Asthma is generally caused by an ongoing or chronic inflammation of these passageways. This leads to an increase in the sensitivity of the person’s breathing airways to several external factors that can trigger an asthmatic attack. When the inflammation is initiated by any one of the several external and internal elements, the airways tend to swell up and get congested with mucus. Then, muscles throughout the breathing airways constrict, which is known as bronchospasm, which leads to a further thinning of the passageways. After which, the narrowing makes it complicated for oxygen to be exhaled from the lungs. This process ends with a resistance to exhaling that causes the common symptoms of an asthma attack, which is loss or difficulty in breathing.
Asthma is an incurable complication that can cripple you as you grow older. People with asthma are, in some cases, limited to activities that are strenuous in order to avoid any unwanted attacks. But fortunately, there are several treatment techniques, either natural or equipment-based, in order to help an asthmatic live their life as normal and active as possible. However, as a famous proverbs goes – prevention is better than cure. To prevent asthma attacks, we should first understand the mechanisms that trigger the health condition. Here are some of the common causes of asthma.
Unfortunately, the definite cause of asthma remains presently unknown. However, what all individuals with asthma have in common is the chronic passageway inflammation and the excess passage sensitivity to different triggering elements. Basically, people with asthma are either born with the condition or develop it in their adulthood. In general, asthma is triggered by either environmental or genetic factors. These elements contribute to the intensity or severity of your asthma attacks and predict how well the client is able to cope up with treatment by means of medication.
A variety of environmental factors have been reported to trigger asthma attacks as well as develop the condition during prolonged periods of exposure to the element or substance. In addition, some environmental factors have even been reported to be fatal to children with asthma. Some of the common environmental causes of asthma include tobacco, hygiene hypothesis, volatile organic compounds, phthalates, and nitrogen oxide, which is apparent in gas cooking stoves. In terms of genes, more than 100 genes have been reported to cause asthma.
