asthma

Asthma is a chronic medical problem that affects the respiratory system.It affects the tubes that bring air into and out of the lungs negatively.More than 17 million Americans suffer from asthma.There are two different types of asthma: Bronchial Asthma which is the inflammation of air tubes, and Cardiac Asthma in which there is fluid in the lungs as a result of heart complications.Asthma causes 5,500 deaths every year in America. Every part of our body needs oxygen to live.This is why complications to the respiratory system can severely threaten your life. The oxygen travels from our mouths to the larynx, then the trachea, and then branches to smaller and smaller sections, by the end it ends up to be alveoli where "breathing occurs".Between the Alveoli and where the wind pipe branch is where the Asthma attack occurs.The bronchi and bronchioles get inflamed, not letting air pass through them as well as normal. The body then tries to breath harder.The symtems go from mild chest pain to stringy mucas.Most things the body does after that produce a higher need for oxygen, and still smaller airways.
Asthma attacks seem to be caused by super reactivity to triggers.The body over reacts to what is happening.Some people react to allergens, such as dust and pollen. Others are caused by chemical irritants such as hairspray, cosmetics, and cleaners.Not all triggers are environmental.Some are cause by internal chemicals or bacteria and viruses.
Doctors check on wheezing, coughing, and shortness of breath during episodes experienced, although finding the trigger is very desirable.Finding some triggers is easy, but some a lot harder.When the trigger is not easy to find skin allergen tests are preformed.Once diagnosed, treatment is fairly easy with Bronchodilators, and anti-inflammatory medicine.
