Causes of Rhinitis

• Viral infections like a cold or flu (this is the one of the most common causes)


• Dust mites’ waste, mold, animal dander, and cockroach debris are frequent indoor culprits of perennial allergic rhinitis.


• Physical malformations such as deviated septum, polyps, cysts can lead to rhinitis.


• Antibiotics (only effective for bacterial infections, not viruses) kills friendly bacteria in your digestive tract as well as targeted harmful bacteria. Overuse of antibiotics can lead to growth of candida fungus and yeast infection that can cause sinusitis.


• Temperature or humidity changes can trigger nasal swelling and cause runny or stuffy nose.


• Pollens from trees, grasses, weeds, or airborne mold spores are the primary causes of seasonal allergic rhinitis.


• Changes in hormones due to pregnancy, oral contraceptive use or a hormonal condition such as hypothyroidism.


• Hot or spicy foods, alcoholic beverages (e.g., beer, wine) may cause nasal membrane to swell and lead to congestion.


• Foods such as nuts, wheat, milk, shellfish, eggs, and red meat are common culprits of allergy.


• Extended use (5-7 consecutive days) of over-the-counter decongestant nasal sprays often, in a rebound effect, leads to more congestion, nasal swelling, and result in permanent damages of tissues.


• Non-steroidal anti-inflammatory drugs (e.g., aspirin, ibuprofen), birth control pills, blood pressure medications, sedatives and antidepressants. I believe these are less common triggers but it would be good to talk to your medical doctor for more information.
