A medical condition caused by an allergy that has symptoms including runny nose and itchy eyes.
An inflammation of the nasal passages, commonly referred to as hay fever.
Inflammation in the nose and eyes caused by an allergic reaction to plant pollen, mould spores, dust mites or animal hair.
Nasal mucous membrane inflammation caused by allergen inhalation; allergies may be seasonal or year-round.
An allergy-related inflammation of the membranes lining the nasal passages, throat, and eyes caused by sensitivity to airborne pollens, molds, and other allergens. Seasonal allergic rhinitis is also known as hay fever.
Also known as hay fever; involves allergic reactions to certain pollens, dust particles, or airborne chemicals.
Within the intricate realm of the human body’s defense mechanisms, a captivating phenomenon manifests as a response to specific allergens. This phenomenon takes the form of inflammation that affects the delicate mucous membranes lining the nasal passages and the eyes. Referred to as allergic rhinitis, this condition is commonly known as hay fever, exhibiting a seasonal pattern of occurrence.
Allergic rhinitis is a widespread condition marked by inflammation of the nasal mucous membrane, usually triggered by allergens like pollen, dust, or other particles in the air. Common symptoms include sneezing, a runny nose, and nasal congestion. In many cases, watery eyes are also present. Additional symptoms can include itching in the eyes, soft palate, and ears. The condition may also cause conjunctivitis, resulting in red and sore eyes.
For some individuals, breathing in particles of seemingly harmless substances, known as allergens, leads to an overactive immune system response. The body produces antibodies against these allergens, which also prompt the release of chemicals like histamine. These chemicals cause inflammation and the production of fluid in the nose and surrounding air cavities, or nasal sinuses. Allergens responsible for allergic rhinitis can include tree, grass, and weed pollens, molds, animal skin scales, hair or feathers, as well as household dust and dust mites.
Commonly referred to as hay fever, seasonal allergic rhinitis is triggered by pollen. Tree pollens are most abundant in the spring, grass pollens dominate the summer, and weed pollens are prevalent in both summer and fall. Symptoms are usually more severe during hot and windy conditions, particularly in areas with abundant vegetation. On the other hand, those affected by indoor allergens like dust experience milder symptoms but endure them year-round, a condition known as perennial rhinitis.
For mild episodes of allergic rhinitis, antihistamine medications and topical corticosteroids are commonly used. Regular inhalation of sodium cromoglicate throughout the pollen season can help in preventing flare-ups by inhibiting the allergic reaction. In some cases, long-lasting symptom relief may be achieved through allergen desensitization, which involves a series of injections.
