Nasal polyps are common, noncancerous, teardrop-shaped growths that form in the nose or sinuses. They’re usually found around the area where the sinuses open into the nasal cavity. Mature ones look like peeled grapes.
Often linked to allergies or asthma, they may cause no symptoms, especially if they're small and don’t need treatment. Larger ones can block normal drainage from the sinuses. When too much mucus builds up in the sinuses, it can become infected.
If you’re among the 37 million Americans who suffer from sinus problems, you know just how miserable the symptoms can make you feel. The congestion. The facial pain. The postnasal drip-drip-drip.
Summer often brings a bit of a respite, as the cold viruses that trigger most cases of sinusitis are less active in warm weather. And, experts say the sinus problems that do crop up in summer can often be avoided -- if you take these six precautions:
Many people also have wheezing, sinus infections, and sensitivity to fumes, odors, dusts, and chemicals. It’s less common, but some people with nasal polyps also have a severe allergy to aspirin and reaction to yellow dyes. If you know you have that allergy, ask your doctor to check for nasal polyps.
Nasal polyps make you more likely to have long-term (chronic) sinusitis. Large ones can even change the shape of your nose.
Who Gets Them?
Anyone can, but they're most common in adults over age 40 and are twice as likely to affect men as women. Children under age 10 rarely get them. If they do, a doctor will check for signs of cystic fibrosis.
Some experts think that symptoms of allergies -- including runny nose, sneezing, and itching -- make some people more likely to get nasal polyps. But the allergy connection is controversial. Other researchers think that sinus infections are to blame.
