Nasal polyps are benign growths that develop in the lining of the nasal passages or sinus cavities. It develops when the mucus membranes in the nose or sinuses become inflamed and swell. Nasal polyps can affect anyone of any age but typically occur frequently in adults. Medication may be able to shrink or eliminate the nasal polyps but if they grow large enough to block the nasal passages or sinuses, surgery may be necessary to remove them.

Causes of Nasal Polyps
Because they are more common in adults, the exact cause of nasal polyps is unknown but they often develop in patients who have asthma or allergies. Other causes of nasal polyps include:

Treatment of Nasal Polyps
There is no cure for nasal polyps. They can be treated with medications such as corticosteroid nasal sprays and pills. If there is a sinus infection, antibiotics may be prescribed. If allergies are the cause of the nasal polyps, immunotherapy may be prescribed. Depending on how severe the condition is, the patient may require surgery to remove the nasal polyps and open up the sinus cavities for proper drainage. Not everyone can prevent the development of nasal polyps. But to reduce or minimize the occurrence or effects of nasal polyps, patients may be advised to:- Use a humidifier
- Undergo immunotherapy to treat allergies
- Use a saline or saltwater nasal rinse
