In the modern world, respiratory diseases have emerged as one of the most prevalent medical conditions affecting individuals of all age groups. The term respiratory diseases is a broad term and as a norm usually covers common respiratory diseases to life threatening conditions that influence the respiratory system. When it comes to respiratory diseases, it is recommended that individuals should have an understanding of the most common causes of respiratory diseases so as to be able to protect themselves from these infections better. This said the following overview on causes of respiratory diseases will help shed more light on this.
Smoking is perhaps one of the leading causes of respiratory infections. Research has shown that cigarette smoke contains over 4000 different toxic chemicals. When inhaled, these chemicals have a detrimental effect on not only the lungs but also the air pipes. For starters, the smoke can progressively destroy the alveoli in the lung bringing about impaired breathing or even constrict the airways incapacitating the breathing process.
People who smoke are also predisposed to respiratory diseases such as pneumonia and tuberculosis. This is because smoking progressively weakens the respiratory with the result being the system being highly susceptible to infections.
Allergens And Pollutants
Allergens are also a major contributing factor when it comes to respiratory diseases. This is because they not only have the capacity to bring about a medical condition but can also trigger a condition such as asthma. As a norm, allergens cause persistent inflammation of the airways resulting in wheezing and even shortness of breath.
Allergens can be in any form with the most common being dust, mite, pet hair and even pollen grains. Pollutants, on the other hand, include asbestos, wood smoke, dust and even heavy industrial smoke.
Deadly pulmonary infections also feature prominently in the list of possible causes of respiratory diseases. As you may well know, there is a class of respiratory illness which is classified as being communicable. Simply put, if you come in close contact with an individual suffering from such a respiratory condition, chances of infection are very high.
Tuberculosis is perhaps one of the most notable in this group. As a norm, it is easily communicable when one inhales mucus droplets from the air after a patient sneezes. Given this, it is recommended that one should employ appropriate measures when close to individuals affected by these conditions so as to avoid getting infected. Common cold, sore throat and influenza are other communicable mild respiratory diseases that fall under this category.
Weak Immune System
As a norm, the human body is exposed to hundreds of infections; including respiratory infections, but in most instances can fight them off. However, for an individual who has a weak immune system, the body is not able to fight off infections that would have otherwise been fought off in a usual scenario, and the result is an illness.
A good example would be a common cold. Frequent bouts of a common cold usually soften the ground for other more severe respiratory infections. To avoid this, it is recommended that an individual should strengthen the immune system through exercising and proper diet.
By taking note of the causes mentioned above of respiratory diseases, an individual can be able to prevent these diseases better
