Nasal polyps: symptoms, causes, treatment, and proper self-care.

Nasal Polyps are more common than many people think and often cause chronic nasal congestion, difficulty breathing, or reduced sense of smell. This article will help you understand the condition from its causes, symptoms, diagnosis, to practical treatment approaches used in hospitals, so you can confidently make health care decisions.
What are Nasal Polyps?
Nasal polyps are benign tumors that arise from chronic inflammation of the nasal mucosa or sinuses, resulting in soft, pale white or grayish tissue growths resembling small grapes or chicks inside the nasal cavity. They are usually painless, non-cancerous, and non-contagious but can cause breathing difficulties, reduced quality of life, or recurrent sinus infections.
What Causes Nasal Polyps?
Nasal polyps result from chronic inflammation of the nasal and sinus mucosa, causing swelling and the formation of polypoid masses. They often arise from multiple factors combined, not just from forceful nose blowing or personal habits alone. Common related factors include:
1. Allergic Rhinitis Allergies to dust, dust mites, pollen, or other allergens cause prolonged nasal mucosa inflammation, leading to polyp formation.
2. Chronic Sinusitis Persistent inflammation in the sinuses causes mucosal swelling and polyp growth.
3. Mucosal Hyperreactivity Such as from inhaling cigarette smoke, pollution, or strong odors, causing repeated mucosal inflammation.
4. Asthma Asthma patients are more prone to nasal polyps due to concurrent airway inflammation.
5. Aspirin-Exacerbated Respiratory Disease (AERD) Individuals allergic to aspirin or NSAIDs often have both asthma and nasal polyps.
6. Genetics Some people have increased sensitivity of the respiratory mucosa, making them more susceptible to polyps, or have nasal structures that impair airflow, such as a deviated nasal septum.
7. Recurrent Infections Especially chronic viral or bacterial infections in the nasal cavity, leading to persistent inflammation.
Symptoms to Watch For
Symptoms of nasal polyps are usually chronic and develop gradually. If symptoms persist for more than 3 months, it is considered a “chronic condition” and should be evaluated by an ENT specialist, including:
๐ Chronic nasal congestion and difficulty breathing
Frequent runny nose or post-nasal drip
๐ Reduced or lost sense of smell
๐ Feeling of facial pressure, heaviness, or sinus pain
๐ Snoring or sleep problems
๐ Chronic cough from post-nasal drip
๐ Some may have nasal voice or feel like something is blocking the nose
How Nasal Polyps Are Diagnosed
Phyathai 2 Hospital uses standardized and appropriate diagnostic methods based on patient symptoms, including:
1. Nasal Endoscopy A small camera is used to closely examine the nasal cavity, clearly detecting polyps even if they are small.
2. Sinus CT Scan Helps assess the severity, distribution of polyps, and abnormalities in the nasal cavity or sinuses, suitable for surgical planning.
3. Medical History and Physical Examination by an ENT Specialist Including allergy history, medication use, and comorbid conditions such as asthma or chronic sinusitis.
Treatment Methods
Treatment depends on symptoms, severity, and underlying causes. Doctors will choose the most appropriate, non-overclaimed, and safest method.
1. Intranasal Corticosteroid Sprays The main approach to reduce inflammation, shrink polyps, and relieve nasal congestion. Use continuously as prescribed.
2. Short-term Oral Anti-inflammatory or Steroid Medications Used only in some severe cases under close medical supervision.
3. Treating Underlying Conditions such as Allergic Rhinitis or Sinusitis May include antihistamines, decongestants, or antibiotics as evaluated.
4. Endoscopic Sinus Surgery Used when polyps are large, significantly block breathing, or do not improve with medication. This minimally invasive surgery removes polyps and improves sinus drainage, with faster recovery than traditional surgery.
Basic Self-Care Tips
๐ Rinse the nose with saline to reduce mucus and inflammation
๐ Avoid allergens such as dust, smoke, cigarette smoke, and pollen
๐ Drink enough water to maintain nasal cavity moisture
๐ Use medications as prescribed regularly
๐ Control chronic diseases such as asthma
๐ Get adequate rest and reduce stress, which can trigger symptoms in some cases
Who is at Risk for Nasal Polyps?
๐ People with chronic allergic rhinitis
๐ People with chronic sinusitis
๐ Asthma patients
๐ People allergic to aspirin or NSAIDs
๐ People with a deviated nasal septum
๐ Those with a family history of nasal polyps
๐ People working regularly in dusty, smoky, or irritating environments
Possible Complications
Although nasal polyps are not cancerous, if left untreated, they may cause:
๐ Chronic nasal congestion reducing quality of life
๐ Reduced sense of smell affecting daily life
๐ Frequent sinus infections
๐ Snoring or sleep apnea
๐ Chronic headaches
๐ In children, may affect sleep development and facial structure
When Should You See a Doctor?
๐ Difficulty breathing or chronic nasal congestion lasting more than 2–3 weeks
๐ Reduced or lost sense of smell
๐ Recurring sinus infections
๐ Excessive post-nasal drip causing chronic cough
๐ Symptoms not improving with self-treatment
๐ Symptoms accompanied by chronic diseases such as worsening asthma
๐ Children with nasal congestion, mouth breathing, or abnormal snoring
FAQ: Frequently Asked Questions about Nasal Polyps
Q1: Are nasal polyps cancerous?
A: No, they are benign tumors but the underlying cause should be investigated as other diseases may coexist.
Q2: Can nasal polyps be cured?
A: Symptoms can be well controlled with medication, management of underlying conditions, and surgery in some cases. Although recurrence is possible, continuous treatment can reduce the risk.
Q3: If I have nasal polyps, do I need surgery?
A: Not necessarily. Many patients improve with steroid nasal sprays and self-care. Surgery is reserved for severe cases or those unresponsive to medication.
Nasal polyps may seem minor but can significantly impact quality of life if untreated, causing breathing difficulties, poor sleep, or recurrent sinus infections.
At Phyathai 2 Hospital, we emphasize safe medical standards with experienced ENT specialists and modern equipment for accurate diagnosis. If you or someone close has chronic nasal congestion, reduced sense of smell, or suspect nasal polyps, we recommend evaluation for advice and personalized treatment planning.
