Nasal polyps are relatively non-dangerous conditions, but can affect the quality of life if left untreated. Polyps are abnormal, non-cancerous, tissue growths inside the linings of the sinuses or nose. Nasal polyps can cause a reduced sense of smell and a feeling of constant stuffiness and discomfort. Discussed herein are the causes of nasal polyps you should know about.

Asthma
One of the main causes of nasal polyps is an existing asthma condition. Asthma is a condition where your airways swell and get narrow, making it difficult for the person to breathe. People with chronic respiratory conditions like asthma are more likely to develop nasal polyps. The exact reason for this is still not very clear.

Allergic Fungal Sinusitis
Another condition that can increase your risk of developing nasal polyps is allergic fungal sinusitis. This is a fungal infection of the sinuses, which can result in sticky and thick mucus and blocked sinuses. Again, people with fungal sinusitis are said to be at a higher risk of developing polyps. Both conditions are seen in conjunction.

Cystic Fibrosis
Another of the common causes of nasal polyps is a condition called cystic fibrosis. This is a hereditary disease that can affect both the lungs and the digestive system. The body produces very thick and unmanageable mucus that can clog up vital organs like the lungs and get fatal. Up to 50% of people with cystic fibrosis seem to have nasal polyps too. The chronic congestion in the nasal pathway and the sinuses result in the development of polyps.

Vitamin-D Deficiency
You might be surprised but one of the causes of nasal polyps is the lack of vitamin D in the system. Many studies being conducted globally show a positive relation between vitamin D receptors and the progression of nasal polyps. The deficiency of vitamin D can cause the development of polyps in the nose and sinuses.

Churg–Strauss Syndrome
This is a condition where a person’s blood vessels get inflamed. Churg–Strauss syndrome is common in patients with airway disorders like asthma and sinuses. Bring diagnosed with this also can be a cause of developing nasal polyps.

Sensitivity to Ceertain Medications
Nonsteroidal anti inflammatory medications like Ibuprofen and aspirin are commonlt used. Some people with sensitivity to these medications can develop nasal polyps quite often. People with a history of nasal polyps are not prescribed such medications for the risk of causing a relapse of the condition.

All these causes of nasal polyps are common, yet not exhaustive. Scientists are still trying to understand what other reasons can trigger the condition and cause the development of abnormal tissue growths. When diagnosed, the mild and moderate cases of polyps can be easily treated with non-invasive treatments. Stubborn growths may need to be surgically removed.
