Asthma (AZ-ma) Is A Chronic (long-term) Lung Disease That Inflames And Narrows The Airways.
Asthma Causes Recurring Periods Of Wheezing (a Whistling Sound When You Breathe),
Chest Tightness, Shortness Of Breath, And Coughing.
The Coughing Often Occurs At Night Or Early In The Morning.
Asthma Effects People Of All Ages,
But It Most Often Starts In Childhood.
In The United States,
More Than 22 Million People
Are Known To Have Asthma.
Nearly 6 Million Of These People Are Children.
Overview ……..
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.
This Chain Reaction Can Result In Asthma Symptoms.
Symptoms Can Happen Each Time The Airways Are Irritated.
