Asthma is a disease affecting the airways that carry air to and from your lungs. People who suffer from this chronic condition are said to be asthmatic. The inside walls of an asthmatic's airways are swollen or inflamed. This swelling or inflammation makes the airways extremely sensitive to irritations and increases your susceptibility to an allergic reaction. As inflammation causes the airways to become narrower, less air can pass through them, both to and from the lungs. Symptoms of the narrowing include wheezing , chest tightness, breathing problems, and coughing. Asthmatics usually experience these symptoms most frequently during the night and the early morning.
Asthma is an incurable illness. However, with good treatment and management there is no reason why a person with asthma cannot live a normal and active life. An asthma episode, or an asthma attack, is when symptoms are worse than usual.
Asthma is caused by inflammation in the airways. When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can pass by. In sensitive people, asthma symptoms can be triggered by breathing in allergy-causing substances.
What happens during an asthma attack?
The muscles around your airways tighten up, narrowing the airway.
Less air is able to flow through the airway.
Inflammation of the airways increases, further narrowing the airway.
More mucus is produced in the airways, undermining the flow of air even more.
In some asthma attacks, the airways are blocked such that oxygen fails to enter the lungs. This also prevents oxygen from entering the blood stream and traveling to the body's vital organs. Asthma attacks of this type can be fatal, and the patient may require urgent hospitalization.
Asthma attacks can be mild, moderate, severe and very severe. At onset, an asthma attack does allow enough air to get into the lungs, but it does not let the carbon dioxide leave the lungs at a fast enough rate. Carbon dioxide - poisonous if not expelled - can build up in the lungs during a prolonged attack, lowering the amount of oxygen getting into your bloodstream.If you don't control your asthma you will miss school or work more often and you will be less likely to be able to take part in some activities you enjoy.
