Sinusitis refers to inflammation of the nasal and facial sinus mucosa, usually caused by bacterial, viral, or fungal infections. Sinusitis can be acute or chronic, depending on the duration and severity of the inflammation.
1、 Common symptoms of sinusitis
1. Nasal congestion: Sinusitis is generally accompanied by a feeling of nasal congestion, lack of nasal ventilation, or difficulty breathing.
2. Increased nasal mucus: Patients with sinusitis usually have symptoms of increased nasal mucus, which may appear yellow green and sometimes have a foul odor.
3. Facial pressure and pain: Sinusitis often accompanies facial pressure and pain, commonly in the forehead, eye area, and cheek region. This pain may be dull or intense.
4. Decreased sense of smell: Sinusitis may cause a decrease in sense of smell or complete loss of olfactory function, and patients may not be able to smell odors or scents that they can normally distinguish.
5. Cough: Due to the backward dripping of sinus mucus into the throat, it may prick the throat mucosa and cause persistent coughing.
6. Headache: Facial pressure and congestion caused by sinusitis can sometimes lead to a headache sensation, usually concentrated in the forehead or frontal area.
7. Fatigue: Due to discomfort caused by sinusitis and the body's response to resolving infections, patients may feel tired and lethargic.
2、 Causes of sinusitis
1. Upper respiratory tract infection: One of the most common causes of sinusitis is upper respiratory tract infection, usually caused by cold viruses, influenza viruses, etc.
2. Bacterial infection: Bacterial infection in sinusitis is usually secondary to bacterial invasion after upper respiratory tract infection. Common bacterial infections include Streptococcus pneumoniae, Haemophilus influenzae, etc.
3. Allergic rhinitis: Allergic rhinitis is an allergic nasal and sinusitis syndrome, usually caused by allergies to allergens in the air (such as pollen, dust mites, etc.). When allergens come into contact with the nasal mucosa, the immune system will overreact, leading to the occurrence of sinusitis.
4. Nasal polyps: Nasal polyps refer to abnormal soft tissue growth in the nasal cavity and sinuses, which can block or obstruct sinus drainage channels, leading to sinus infections and inflammation.
5. Immune system issues: People with weakened or defective immune system function, such as chronic disease patients, are more likely to suffer from sinusitis than the general population.
3、 Measures to prevent sinusitis
1. Maintain good personal hygiene habits: wash hands frequently and avoid touching the nose, eyes, and mouth with your hands. When coughing or sneezing, cover your mouth and nose with tissues or elbows to avoid spreading viruses and bacteria to others.
2. Avoid contact with sources of infection: Try to minimize contact with known sources of infection, such as patients with respiratory infectious diseases such as colds and flu, and avoid crowded and poorly ventilated public places, especially during seasons when virus transmission is more likely to occur.
3. Regular vaccination: Vaccination is an effective way to prevent certain respiratory infections, and timely vaccination can help improve immunity and reduce the risk of infection.
4. Keep indoor air moist: A dry indoor environment may irritate the nasal mucosa, leading to a higher risk of sinusitis. Keeping indoor air moist can alleviate discomfort and avoid dry nasal mucosa.
5. Avoid nasal irritants: Reduce contact with substances that irritate the nasal mucosa, avoid smoking and passive smoking, as tobacco smoke can exacerbate nasal inflammation.
6. Maintain good nasal hygiene: Regularly cleaning the nasal cavity with warm saline can help remove dirt, secretions, and bacteria from the nasal cavity.
7. Balanced diet and healthy lifestyle: Maintaining a balanced diet and consuming sufficient nutrients can help enhance immune system function. Regular exercise, adequate sleep, and stress reduction also have a positive effect on maintaining physical health and resisting infections.
Sinusitis is a common disease that has a significant impact on an individual's quality of life. Early diagnosis and treatment, following the doctor's advice for treatment and prevention measures, can help alleviate symptoms, promote recovery, and prevent recurrence. If symptoms of sinusitis occur, please seek medical attention promptly and follow the doctor's treatment advice. Early diagnosis and treatment can help alleviate symptoms and reduce the possibility of recurrence.
