What is Asthma? The Definition of Asthma
What is Asthma? Asthma is a condition that has affects the airways. Our airways are of great importance to our health, as they carry the air to and from our lungs. Generally, people who experience asthma for a long time or suffer from the recurrence of asthma, can be called as asthmatic. The inner walls of these people’s airways are inflamed or swollen, which increases their susceptibility to allergens and makes them highly sensitive to some irritations. The inflammation makes the airways become narrower, so the air that can flow through them, either to or from the lungs, becomes less. And narrowed airways can cause many symptoms, such as wheezing, coughing, chest tightness or breathing difficulties. For asthmatics, these symptoms are especially frequent in the early mornings or during the night.
People may wonder whether if asthmatics are treated with reasonable medication, it is possible to cure asthma. The fact is that asthma is incurable. However, the good news is that there are no specific reasons why people with asthma can’t have normal activities and lead normal lives.
How do Asthma Attacks or Episodes Happen?
When asthma symptoms suddenly worsen and become more frequent, this means the person is experiencing asthma attacks or asthma episodes. These sudden attacks can happen moderately or severely. But why do asthma attacks cause such bad reactions? Actually, during asthma attacks, the muscles next to the airways are tightened up, which narrows the airways accordingly. And inflammation of the inside walls can also be aggravated by asthma attacks as they also narrow the airways. And the air can hardly pass through. What’s worse, increasing mucus is generated into the airways, which undermines the air flows.
For certain asthma attacks, it’s easy for the airways to be blocked. Blocked airways can prevent oxygen entering sufferers’ lungs, and the oxygen also neither can enter the blood stream nor flow to other vital organs. This type of asthma attack is generally fatal, and it often requires urgent hospitalization.
The condition of asthma attacks could be mild, moderate, severe or extremely severe. When they begin, the lungs can’t get enough air and carbon dioxide can’t exit the lungs at an adequate speed. If it isn’t expelled instantly, this poisonous substance can calculate in the patient’s lung when attacks reoccur continually and prevent oxygen from flowing to the bloodstream.

If you are suffering from asthma, it’s best to seek the help of your doctor. He will examine your conditions, help you pinpoint asthma triggers and suggest how to reduce or avoid these triggers. And he can also prescribe medication to control your symptoms.
