Asthma is a chronic disease affecting the airways that carry air to and from your lungs. It is the condition in which your airways narrow and swell up and produce extra mucus. For some people, asthma is a minor and others, it can be a major problem that affects daily activities and may lead to severe asthma attack.
Asthma symptoms include:
- Chest tightness
- Breathing problems
Symptoms are usually worse at night and in the early morning or in response to exercise or cold air. Asthma attack can be triggered by allergens, exercise, and pollution smoke or airways infections. Asthma can’t be cured, but its symptoms can be controlled. Asthma can be controlled with good treatment and proper management.
Major Cause of Asthma
Asthma is caused by environmental and genetic factors. These factors influence both its severity and its responsiveness to treatment. It is believed that the recent increased rates of asthma are due to changing epigenetic and living environment.
Intensity of Asthma Attack
Asthma attacks can be mild, moderate, severe and very severe. 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 protracted attack, lowering the amount of oxygen getting into your bloodstream.
During an Asthma attack, muscles around airways squeeze 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 essential organs. Asthma attacks of this type can be serious, and the patient may require urgent hospitalization.
