Bacterial sinusitis is a bacterial infectious inflammation of the sinuses. The main symptoms include nasal congestion, runny nose, headache or localized pain, and decreased sense of smell. Pathogenic factors include systemic factors, local factors and so on.
1. Systemic factors: overwork, malnutrition and other causes of systemic immunity, leading to bacterial invasion, thus causing the occurrence of sinusitis. In addition, unclean living and working environment, systemic underlying diseases (such as diabetes, anemia), upper respiratory tract infections and acute infectious diseases (influenza, measles, etc.) can be induced by this disease.
2. Local factors:
(1) Nasal diseases: such as acute and chronic rhinitis, nasal septal deviation, nasal polyps, variant rhinitis and other diseases can block the sinus mouth and nasal tract complex, thus impeding sinus ventilation and drainage and triggering sinusitis.
(2) Focal infection of neighboring organs: such as adenoiditis, tonsillitis and other inflammatory diseases, often accompanied by inflammation of the nasal cavity and nasopharynx, easily implicated in the nearby sinuses and cause sinusitis.
(3) Traumatic: If you blow your nose hard after swimming, it may cause sewage to enter the sinuses, triggering bacterial infection and causing sinusitis.
(4) Medical factors: If the fillings are left in place for too long, secondary infection or blockage of sinus drainage can also lead to bacterial sinusitis.
(5) Changes in air pressure: Because of the negative pressure in the sinus cavity caused by changes in air pressure, inflammatory secretions or dirt are inhaled into the sinuses, which can cause bacterial sinusitis.
If the above symptoms of bacterial sinusitis occur, it is recommended to go to the hospital in time for early formal treatment.
