Asthma can be allergic or genetic. It can be caused due to a person being allergic to dust for example or by sudden rapid changes in temperatures or due to consumption of heavy medicines which has its side effects. Asthma can affect people of all ages and and it is believed that nearly 6 million people in the world alone in US affected by Asthma are children.
From the image will explain easily to all that how it is caused.
The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. This makes the airways swollen and very sensitive. They tend to react strongly to certain substances that are breathed in.
When the airways react, the muscles around them tighten. This causes the airways to narrow, and less air flows to your lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways may make more mucus than normal. Mucus is a sticky, thick liquid that can further narrow your airways.
Asthma can be classified as atopic(allergy) or non atopic(non allergic).
Signs and Symptoms
Very few patients out of the millions of people who suffer from asthma may be able to mark signs that triggers it as it might be different for most of them.
Common symptoms of Asthma are
- Wheezing in the chest area.
- Coughing which can be wet or dry.
- Breathlessness even in open air
- Tightness in the chest
So keep this always in mind and take necessary corrective action.
Asthma cant be cured but can be prevented so don't be depressed as people have conquered the world even if they are asthmatic.They can live normal, active lives and sleep through the night without interruption from asthma.
