Learn more about the causes of sinus infections

Sinus infection is not completely contagious, but, depending on the cause of the infection, other people may also get sick, and the infection may eventually develop due to sinus obstruction, depending on the degree and severity of the obstruction.

In healthy people, secretions from the mucosa move and still enter the nasal cavity, but when occlusion occurs, the mucus does not flow properly, increases its thickness, fills the voids Sinus and eyelashes slow down and cleanse, making it more difficult to expel mucus. When the mucus is unable to flow, the medium becomes ideal for microbes that grow uncontrollably and cause an infection.

There are many underlying causes of sinus obstruction, including various environmental, anatomical, and genetic factors, but the most common cause is inflammation or swelling of the nasal passages due to colds or to allergies.

– Common colds and sinuses:

Viral infections associated with colds are the most common cause of sinus infection, also called viral sinusitis. In this case, the virus can spread to other people, causing colds that can also develop into viral sinusitis.

In only 0.5 to 2% of cases, bacterial sinusitis, a sinus infection caused by a bacterium, is not contagious.

In rare cases, fungi can cause sinus infection, especially if the person has innate sensitivity, but fungal sinusitis does not often affect people with healthy immune systems.

Sinus infection can affect ocular tissues and cause inflammation of the orbital tissues or accumulation of pus behind the eyes. In some cases, sinus infection can cause clotting in nearby blood vessels, a disease called coagulation of the cavernous sinuses.

If the infection spreads through the skull, it can affect the brain. It can cause meningitis or brain abscesses, sometimes an infection of the bones and the skin can also be infected, resulting in inflammation of the cell tissue or abscesses of the skin. Complications can be life threatening and require immediate medical attention.

– Causes of sinusitis:

The obstruction and inflammation of the sinuses have many causes that can increase the risk of sinus infections. They are risk factors and may increase the risk of chronic infection or worsening of symptoms, including:

– Sensitivity.

– nasal polyps (abnormal growth in the nose).

– Nervous deviation (curvature in the wall between the two openings).

– Disorders or weakness of the immune system and the immune system, due to diseases such as uncontrolled diabetes, HIV / AIDS or as a result of certain treatments such as chemotherapy.

– Facial fractures as a result of trauma limiting the nasal passages.

– Scar tissue resulting from surgery at the nose.

– Congenital diseases such as cystic fibrosis, which causes mucus build up in the lungs and continuous lung infection.

– Asthma and other diseases as side effects and reactions and reactions.

Exposure to tobacco smoke or other irritants suspended in the air.

– Viral infections, including colds.

– For children, the causes include: use of contaminated salts, consumption of alcohol while lying down, exposure to second-hand smoke.

According to experts The most common type includes swelling and inflammation of the mucous membranes due to various factors other than birth, such as allergies or allergies to allergens and toxins in the air, followed by benign tumors of the nose, sufficiently fat to fill the sinuses, and we do not always know why. Some people contract these benign tumors, others not, then the strong allergic reaction of the fungus present in the air, causing the production of thick and thick mucus.
