Most people can agree to the fact that the human nose is susceptible to many diseases. The nose is actually more exposed to several types of bacteria, viruses, and fungi which cause sinus infection. Sinus infection is basically an inflammation that occurs in the passages of the nose which may result in nasal and eye pressure as well as pressure one of the hemispheres of the brain.

Sinus infection normally results from virus which infects the higher parts of the breathing system. However, certain factors have also been discovered to play a critical role in causing this disease. For instance, allergens or smoke from pollution can also cause a serious manifestation of the disease among potential victims.

Severe damage of the cells of the sinus which leads to selling also causes sinus infection. What follows is that the lining grows thicker and this eventually blocks the nasal passage which branches out. In effect, this causes a disruption to the natural process of eliminating bacteria which are found on these passages giving them opportunity to multiply and take control of the sinus linings.

Streptococcus pneumoniae and two other types of bacteria have also been found to cause sinus infection. These bacteria are innocuous in small numbers hence they do not actually cause the infection but when they start multiplying and control the upper parts of the respiratory tract they trigger the disease. In addition, the common cold has also been fronted as another cause of this disease. The common cold triggers the same effect as the foregoing causes, that is, inflammation in the nose which hinders effective drainage. Frequent exposure to nasal irritants that are present in the air that we breathe may actually contribute significantly to the development of this infection.

Research also seems to support the assertion that specific types of fungi also play a significant role in causing sinus infection more so in individuals who have certain diseases that normally weaken the body’s defense mechanism in humans. Fungi are common in the air around us but most of it is innocuous. One type of fungi that has been found to cause sinus infection is the black mold which is common in damp environments. Too much exposure may lead to build which triggers the infection.

Knowledge on what causes sinus infection will keep you informed and help you look for ways to minimize the possibility of its emergence.
