What is allergic rhinitis?

Allergic rhinitis, also known as pollenosis or hay fever, is an allergic inflammation of the nasal airways .

Classification:

  • Seasonal—occurs particularly during pollen seasons. Seasonal allergic rhinitis does not usually develop until after 6 years of age.
  • Perennial—occurs throughout the year. This type of allergic rhinitis is commonly seen in younger children.
  • Allergic rhinitis may also be classified as
  • Mild-Intermittent
  • Moderate-Severe intermittent
  • Mild-Persistent, and Moderate
  • Severe Persistent

 

Causes:-

  • Allergic rhinitis happens when an allergen (an allergy-producing substance, such as pollen) causes your body to defend itself by producing antibodies.
  • When an allergen and an antibody combine, your body releases histamine and other chemical substances into your bloodstream, which causes an allergic response.
  • Pollen, dust, mold or other substances that can be inhaled, are common allergens that cause symptoms.
  • Seasonal allergic rhinitis usually results from tree, grass, weeds or pollen and is experienced during summer.
  • Perennial allergic rhinitis can cause year-round symptoms.

Signs and Symptoms

  • A stuffy nose or a runny nose.
  • Sneezing.
  • Itchy nose, itchy eyes or watery eyes.
  • Children who have allergic rhinitis might have dark circles under their eyes, or use the palm of their hand to push their nose up as they try to stop the itching (called the “allergic salute”).
  • Coughing caused by clear mucus running down the back of your throat.
