What is asthma?
Asthma can be best described as a respiratory condition which evidence itself by bouts of spasms which takes place in the bronchi of lungs. This can make it very difficult for a person to breathe normally. Several symptoms may be evident such as tightness of chest, wheezing, trouble sleeping, shortness of breath, coughing and even chest pain. Almost one out of every 10 people are suffering from asthma. According to available statistics, approximately 300,000,000 people around the world are now suffering from asthma. Under normal conditions, asthma is not considered to be a debilitating disease. Statistics tell another story and that is that in 2011 over 250,000 people have died because of asthma. Medical science has not yet discovered a cure for asthma. The best they can do is to provide medication which can help to control the symptoms.
How asthma affects the body?
According to medical research, asthma causes inflammation of air passages. This has the result that a narrowing of the airways occurs and therefore less oxygen finds its way to the lungs. It can be extremely difficult for people to breath who are suffering from asthma. A healthy person can easily breathe in because the muscles around the throat will relax and oxygen can move freely through the body. In a person who is suffering from asthma, the bronchial tubes will be red and swollen. There will also be an insignificant amount of inflammation in the airways. This will happen because of several environmental factors such as fumes, dust and also cold conditions can result in a tightening of the muscles which is situated around the air passages. Such a person will then suffer from shortness of breath.
