Asthma: Causes, Prevention And Treatment

Asthma is a condition where the airways become narrow and swollen. The airways produce extra mucus. Mucus can cause breathing difficulties and trigger coughing. For some people, this condition is just a minor nuisance. It is good to know that the discovery of asthma as an acute respiratory disorder began in 400BC. The word Asthma was first coined by Hippocrates. He used this term in his popular book named Corpus Hippocratocum. Also, Hippocrates provided a clear definition of the medical term.

During his discovery, Hippocrates linked asthma symptoms to environmental triggers. In his research, the well-known scientist suggested that the most reliable remedy was drinking a mixture of blood and wine. Another Greek physician composed a detailed definition of this condition in 100 A.C. It was very similar to the modern understanding of how asthma develops.

More than 30 million people in the United States of America are suffering from this condition. About 8 million of these are children. The World Health Organization has estimated that this number might increase with over 60 percent in the next few years. Since 1980, the number of deaths has been doubling year by year. Medical figures have been aware of this condition since ancient Greece.

Being a complicated disease, it is good to understand the symptoms, causes, types, treatment and prevention of asthma. You must carefully monitor your disease. In this article, we will take a look at the most crucial things you should know about asthma.
