You may help reduce your chances of developing nasal polyps or having nasal polyps recur after treatment with the following strategies:
- Manage allergies and asthma. Follow your doctor's treatment recommendations for managing asthma and allergies. If your symptoms aren't well-controlled, talk to your doctor about changing your treatment plan.
- Avoid nasal irritants. As much as possible, avoid breathing airborne substances that are likely to contribute to inflammation or irritation of your nose and sinuses, such as allergens, tobacco smoke, chemical fumes, and dust and fine debris.
- Practice good hygiene. Wash your hands regularly and thoroughly. This is one of the best ways to protect against bacterial and viral infections that can cause inflammation of the nasal passages and sinuses.
- Humidify your home. Use a humidifier if the air in your home tends to be dry. This may help moisten your breathing passages, improve the flow of mucus from your sinuses, and help prevent blockage and inflammation.
Use a nasal rinse or nasal lavage. Use a saltwater (saline) spray or nasal lavage to rinse your nasal passages. This may improve mucus flow and remove allergens and other irritants.
You can purchase over-the-counter saline sprays or nasal lavage kits with devices, such as a neti pot, to administer a rinse.
If you make your own rinse, use water that's distilled, sterile, previously boiled and cooled, or filtered using a filter with an absolute pore size of 1 micron or smaller to make up the irrigation solution. Also be sure to rinse the irrigation device after each use with similarly distilled, sterile, previously boiled and cooled, or filtered water and leave open to air-dry.
