What are Nasal Polyps? Symptoms, Causes, and Treatment Process

Nasal polyps are soft, painless, and teardrop-shaped structures developed on the lining of the nasal passages or sinuses. These growths (nasal polyps) are non-cancerous and harmless, and mostly happen in individuals with asthma, allergies, repeated infections, or nasal inflammation.

To understand this condition deeply, read this blog till the end, which involves nasal polyps treatment, causes, symptoms, and recovery processes.

What Are Nasal Polyps?

Nasal polyps are soft, painless growths that form on the lining of the nasal passages or sinuses due to long-term inflammation. These are painless or benign growths in the nasal passages that usually appear on both sides of the nose.

Polyps are soft, fleshy, or yellow in appearance and can grow large enough to block the nose or cause sinus issues. Over time, these growths may enlarge and block the nasal passages, making breathing difficult.

Nasal polyps are more commonly seen in adults between 30 and 50 years of age, especially in men. Particularly, the risk increases after this age, resulting in chronic sinus infections, obstructive sleep apnea, or even altering the facial structure.

Common Causes and Risk Factors of Nasal Polyps

Nasal polyps are often caused by:

Chronic Inflammation: Long-term irritation or inflammation of the sinuses that often lasts for 2 months or more.

Allergic Rhinitis: Persistent allergies such as allergic rhinitis, sneezing, nasal congestion, or seasonal allergies may irritate the nasal lining and increase the risk of nasal polyps.

Asthma: Individuals with asthma, especially chronic asthma, are more susceptible to the formation of nasal polyps.

Aspirin Sensitivity: People who are sensitive to aspirin or NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) have a higher chance of developing nasal polyps.

Risk factors include:

1. Recurrent infection increases inflammation in the nasal lining and also damages it.
2. Cystic Fibrosis is a genetic condition that causes thick mucus buildup in the nasal passages, increasing the risk of nasal polyps.
3. Genetics plays a vital role; if the parents have polyps, it means a higher chance of developing in their children.

Symptoms of Nasal Polyps

If nasal polyps are smaller in the nose, they may not cause symptoms, but if they get bigger, you may see these symptoms:

1. Blocked or stuffy nose
2. Difficulty breathing through the nose
3. Reduced or complete loss of smell
4. Postnasal drip
5. Frequent sinus infections
6. Headache or facial pressure
7. Snoring or sleep apnea
8. Reduced sense of taste

In some cases, a deviated nasal septum may also contribute to long-term nasal blockage.

How Nasal Polyps Are Diagnosed

Nasal polyps are diagnosed by expert ENT surgeons through the following specialised methods or procedures. But in the initial appointment phase, your healthcare provider may ask some questions or perform some basic steps:

• Use nasal endoscopy (a small or thin tube with a light or camera) to look deep inside your nasal passages, detecting nasal polyps.
• The ENT specialist may also ask about your symptoms, allergy history, breathing problems, and previous sinus infections.

To analyse more about polyps, they may also use these methods:

• CT scan: It is commonly used to analyse the exact size or location of the nasal polyps.
• Biopsy: A doctor may take a small sample of the tissue to check for critical polyps.
• Allergy Testing: This helps doctors identify allergens that lead to nasal inflammation and polyps.

Nasal Polyps Treatment Options

Nasal polyps treatments are based completely on the severity of the condition. Both medications and surgery are the best approaches, depending on the severity.

What medications can be used:

Medications are usually the first line of treatment and help reduce inflammation, shrink nasal polyps, and improve breathing symptoms.

• Steroid Nasal Sprays are commonly used to shrink polyps or reduce inflammation.
• Oral/Injectable Corticosteroids are used when sprays don’t work effectively. Oral pills like prednisone may be used. While in some cases, injectable steroids are also given into the polyps.
• Biological medications like dupilumab injections are used to shrink polyps and improve symptoms.
• Aspirin Desensitization doses are given if you have sensitivities to aspirin.

Sometimes, antibiotics are also given if you have an infection.

Surgery options

Surgical treatments are only used if medications won’t work, or polyps are larger. These are the procedures your healthcare provider may perform:

Functional Endoscopic Sinus Surgery (FESS)

In this surgical process, a surgeon uses a thin endoscope with small medical instruments to remove polyps, infected tissues, clear out sinuses, and other things that become a hindrance to the nasal passage. FESS is considered one of the most effective and minimally invasive procedures for chronic nasal polyps and sinus blockage. Learn more about Functional Endoscopic Sinus Surgery (FESS) and how it helps treat chronic sinus blockage and nasal polyps.

Balloon Sinuplasty

A small inflatable balloon is inserted through your nostril and into your sinus cavity. Surgeons inflate the balloon to extend or unblock the nasal passages.

Polypectomy

If polyps are easily accessible, then polypectomy is used. Surgeons use a small instrument (suction device – microdebrider) to remove nasal polyps from your nose.

Recovery and Aftercare of Nasal Polyps Treatment

After having surgery, Most patients experience improved breathing and relief from nasal blockage after treatment, and they get relief by breathing freely without obstruction in their nose. Recovery from nasal polyps surgery takes time and proper care, and for this, you must follow the following instructions or steps:

Immediate Post-Treatment Process (1 to 5 Days)

• Your nose is covered with a dressing to prevent bleeding, and it is removed by the surgeon after 1 or 2 days.
• You may see common symptoms like fatigue, headache, nasal congestion, and mild facial aching.
• Your doctor will change the dressing if bleeding is steady. Or you can also sit and tilt your head forward and use a saline spray to manage it.
• Rest with your head elevated during the first few days to reduce swelling and discomfort.

Aftercare

Take the prescribed medication by an expert doctor to reduce swelling, inflammation, and pain. However, maintaining hygiene is your task, performing saline rinses 2-3 times daily to remove blood, crusts, and debris.

Other medications, such as steroid nasal sprays or drops, are used to reduce inflammation.

What to Avoid

• Avoid blowing your nose, as it can trigger bleeding.
• Don’t try to lift heavy or bend over until you fully recover.
• Stay away from irritants like smoke, alcohol, dust, and fumes.
• Avoid taking hot showers, hot drinks, and beverages for at least 2 weeks, as these can increase blood flow, increasing the risk of bleeding.

When to Consult an ENT Specialist

A doctor visit is necessary before or after nasal polyps treatment. Proper care ensures better recovery and significantly reduces the risk of recurrence or regrowth of the polyps. Persistent nasal blockage and recurring sinus infections are important signs that should not be ignored.

These are the symptoms that may indicate the need for nasal polyps treatment:

• Persistent Nasal Obstruction
• Loss of smell and taste.
• Chronic drainage
• Facial pain/pressure
• Recurring sinus infections

If you have already undergone the surgical procedure, follow-up visits to the doctor are crucial. However, if you face the following symptoms after surgery, then you must consult a doctor:

• Vision changes
• Clear fluid leakage
• Neck stiffness
• Heavy bleeding
• Signs of infection

Can Nasal Polyps Return After Treatment?

Yes, nasal polyps can recur, especially in people with chronic allergies, asthma, or sinus inflammation. Regular follow-ups with an ENT specialist, saline rinses, and prescribed nasal sprays help reduce the risk of recurrence.

Conclusion

Nasal polyps can significantly affect breathing, sleep, and overall quality of life if left untreated. Early diagnosis and proper treatment help prevent complications and improve long-term nasal health. If you experience persistent nasal blockage, loss of smell, or recurring sinus infections, consult an experienced ENT specialist for an accurate diagnosis and personalised treatment.
