Allergy refers to the immune system's exaggerated response to substances that are typically harmless, triggering an immune reaction. Common allergens include pollen, dust mites, pet dander, fungus, cockroach, certain foods, or insect venom, leading to symptoms such as sneezing, itching, swelling, or difficulty breathing.

Allergy can manifest in various forms, affecting different parts of the body:

  • Respiratory Allergies:Common types include allergic rhinitis (hay fever), triggered by airborne allergens like pollen or dust, and allergic asthma, causing breathing difficulties due to allergens such as dust mites, pet dander, or mold.

  • Skin Allergies: Atopic dermatitis (eczema) is a prevalent allergic skin condition characterized by red, itchy rashes, often associated with allergies to certain foods, environmental factors, or irritants.

  • Food Allergies: Reactions to certain foods, such as peanuts, tree nuts, shellfish, eggs, milk, or wheat, can cause allergic symptoms ranging from mild hives to severe anaphylaxis.

  • Insect Sting Allergies: Allergic reactions to insect venom from stings, such as those from bees, wasps, hornets, or fire ants, can range from localized swelling and itching to severe systemic reactions.

  • Medication Allergies: Some individuals may experience allergic reactions to medications like antibiotics (e.g., penicillin), non-steroidal anti-inflammatory drugs (NSAIDs), or certain anesthesia, causing symptoms from mild rashes to severe anaphylaxis.


Nasal polyps are associated with irritation and swelling (inflammation) of the lining of your nasal passages and sinuses that lasts more than 12 weeks (chronic sinusitis).

However, it’s possible to have chronic sinusitis without nasal polyps.

Nasal polyps themselves are soft and lack sensation, so if they’re small, you may not be aware you have them. Multiple growths or a large polyp may block your nasal passages and sinuses.

Common signs and symptoms of chronic sinusitis with nasal polyps include:

  • A runny nose
  • Persistent Stuffiness
  • Postnasal Drip
  • Decreased or absent sense of smell
  • Loss of sense of taste
  • Facial pain or headache
  • Pain in your upper teeth
  • A sense of pressure over your forehead and face
  • Snoring
  • Frequent Nosebleeds

Risk Factors

Any condition that triggers long-term irritation and swelling (inflammation) in your nasal passages or sinuses, such as infections or allergies, may increase your risk of developing nasal polyps.

Conditions often associated with nasal polyps include:

  • Asthma, a disease that causes the airway to swell (inflame) and narrow
  • Aspirin sensitivity
  • Allergic fungal sinusitis, an allergy to airborne fungi
  • Cystic fibrosis, a genetic disorder that results in abnormally thick, sticky fluids in the body, including thick mucus from nasal and sinus linings
  • Churg-Strauss syndrome (eosinophilic granulomatosis with polyangiitis), a rare disease that causes the inflammation of blood vessels
  • Vitamin D deficiency, which occurs when your body doesn’t have enough vitamin D

Your family history also may play a role. There’s some evidence that certain genetic variations associated with immune system function make you more likely to develop nasal polyps.

Nasal polyps can cause complications because they block normal airflow and fluid drainage, and also because of the long-term irritation and swelling (inflammation) underlying their development.

Potential complications include:

  • Obstructive sleep apnea: This is a potentially serious condition in which you stop and start breathing frequently during sleep.
  • Asthma Flare-Ups: Chronic sinusitis can worsen asthma.
  • Sinus Infections: Nasal polyps can make you more susceptible to sinus infections that recur often.
