Treat Your Allergies

Nasal polyps are noncancerous growths inside your nasal passages or sinuses. We don't know exactly what causes them. But they're often linked to asthma and allergies. If you have seasonal or other allergies, stick with your doctor's plan to treat them. That helps you avoid inflammation that makes polyps worse.

Avoid Dust

Whether or not you're allergic to dust particles, they irritate your nasal passages. Keep your living space wiped down and steer clear of dusty areas. If you know you’ll be where dust lives, wear a mask to keep it out of your nose.

Stay Away From Fumes

Polyps can make your nose feel blocked, much like a cold. Smoke, chemical smells, and other fumes raise your risk of irritation that makes this symptom worse. Avoid secondhand smoke and incense. Stay in a well-ventilated area when you use strong cleansers or other chemicals at home or on the job.

Use a Nasal Rinse

A good wash with a saline nasal rinse can flush out allergens and other irritants that hang out in your nasal passages. You’ll also moisten the area and help it heal. You can buy saline nasal sprays, nasal wash kits, and neti pots over-the-counter.

Bump Up the Humidity

Use a humidifier to add moisture to your indoor air. This improves the flow of mucus in your sinuses and helps prevent blockages. Just be sure to keep your machine clean so you’re not introducing bacteria into the air. It's best to clean it every day.

Tame Your Asthma

Inflammation from nasal polyps can may make your asthma symptoms worse. And keeping asthma under control can help prevent polyps. So it's extra important to manage your asthma when you're prone to polyps. Talk to your doctor if your current treatment isn't doing the job.

Practice Good Hygiene

Well-washed hands carry fewer germs that can get into your nasal passages and cause infections and inflammation. Keep clean by scrubbing your hands properly and often. And try to avoid touching your mouth and nose.

When to See a Doctor

If you’re having trouble breathing, your symptoms are getting worse over time, or you notice changes to your sense of smell, call your doctor. You may need different treatment, or even surgery
