	Allergic rhinitis is caused by an ~~allergic reaction to airborne substances~~, ~~known~~ as [[~~Allergen\|allergens~~]]~~. Common allergens include pollen~~, dust ~~mites~~, mold ~~spores~~, ~~and animal dander. When these allergens are inhaled, they stimulate the immune system of susceptible individuals to produce~~ [[~~Immunoglobulin E\|IgE antibodies~~]]. ~~Upon subsequent exposure, these antibodies bind to the allergens, triggering~~ a ~~cascade of immune responses~~ that ~~result in the release of histamines and other inflammatory substances from mast cells and basophils in the nasal and ocular tissues~~.		'''Allergic rhinitis''' is an [[inflammation]] of the inside of the [[nose]] caused by an [[allergen]], such as [[pollen]], [[dust]], [[mold]], or [[flakes of skin]] from certain animals. It is a common condition that affects many people worldwide.

	==~~= Clinical Presentation~~ and ~~Symptoms =~~==		==Signs and symptoms==
			The symptoms of allergic rhinitis include:
			* [[Sneezing]]
			* [[Itchy]] nose, eyes, or roof of the mouth
			* [[Runny nose]]
			* [[Nasal congestion]]
			* [[Postnasal drip]]
			* [[Cough]]
			* [[Fatigue]]

	~~The primary~~ symptoms ~~of allergic rhinitis include frequent sneezing, nasal congestion, runny nose,~~ and ~~itchy~~ or ~~watery eyes. It may also cause postnasal drip, which can lead to coughing, throat irritation~~, ~~and a decreased sense~~ of ~~taste and smell~~.		These symptoms can vary in severity and may be seasonal or perennial, depending on the type of allergen involved.

	Allergic rhinitis is ~~often associated with other allergic conditions such as~~ [[~~Asthma~~]], [[~~Atopic Dermatitis~~]], and [[~~Conjunctivitis~~]]~~. The severity of symptoms can vary greatly between individuals and may be influenced by the level of allergen exposure and individual sensitivity.~~		==Causes==
			Allergic rhinitis is triggered by an [[immune system]] response to an allergen. Common allergens include:
			* [[Pollen]] from trees, grasses, and weeds
			* [[Dust mites]]
			* [[Animal dander]]
			* [[Mold spores]]

	~~=== Diagnosis ===~~		When a person with allergic rhinitis inhales an allergen, their immune system mistakenly identifies it as harmful and releases [[histamine]] and other chemicals, leading to the symptoms of an allergic reaction.

	Diagnosis of allergic rhinitis is typically based on ~~the patient's~~ history, physical examination, and ~~response to therapy~~. Skin ~~testing or allergen-~~specific IgE ~~blood tests may be used to identify the specific allergens causing the symptoms.~~		==Diagnosis==
			Diagnosis of allergic rhinitis is typically based on a combination of medical history, physical examination, and allergy testing. Common diagnostic methods include:
			* [[Skin prick test]]
			* [[Blood test]] for specific [[IgE antibodies]]
			* [[Epicutaneous test]]

	=== Treatment ===		==Treatment==
			Treatment for allergic rhinitis aims to relieve symptoms and may include:
			* [[Antihistamines]]
			* [[Decongestants]]
			* [[Nasal corticosteroids]]
			* [[Allergen immunotherapy]]

	~~Treatment strategies for~~ allergic rhinitis aim to reduce symptoms by avoiding allergens, using pharmacological therapies, or undergoing immunotherapy. Pharmacological treatments include antihistamines, decongestants, corticosteroid nasal sprays, and leukotriene receptor antagonists. Immunotherapy, such as allergy shots or sublingual tablets, may be an option for individuals with severe symptoms or those who do not respond to other treatments.		Avoidance of known allergens is also a key strategy in managing allergic rhinitis.

	== ~~See Also~~ ==		==Prevention==
			Preventive measures for allergic rhinitis include:
			* Keeping windows closed during high pollen seasons
			* Using air filters
			* Regular cleaning to reduce dust and mold
			* Avoiding exposure to pets if allergic

Allergic rhinitis, colloquially known as hay fever, is a type of [[Inflammation|inflammatory]] response that occurs in the nasal passages and conjunctiva (the white of the eyes). This condition is primarily driven by an allergic response and leads to a variety of symptoms including sneezing, rhinorrhea (runny nose), and ocular discomfort.

=== Etiology and Pathophysiology ===

Allergic rhinitis is caused by an allergic reaction to airborne substances, known as [[Allergen|allergens]]. Common allergens include pollen, dust mites, mold spores, and animal dander. When these allergens are inhaled, they stimulate the immune system of susceptible individuals to produce [[Immunoglobulin E|IgE antibodies]]. Upon subsequent exposure, these antibodies bind to the allergens, triggering a cascade of immune responses that result in the release of histamines and other inflammatory substances from mast cells and basophils in the nasal and ocular tissues.

=== Clinical Presentation and Symptoms ===

The primary symptoms of allergic rhinitis include frequent sneezing, nasal congestion, runny nose, and itchy or watery eyes. It may also cause postnasal drip, which can lead to coughing, throat irritation, and a decreased sense of taste and smell.

Allergic rhinitis is often associated with other allergic conditions such as [[Asthma]], [[Atopic Dermatitis]], and [[Conjunctivitis]]. The severity of symptoms can vary greatly between individuals and may be influenced by the level of allergen exposure and individual sensitivity.

=== Diagnosis ===

Diagnosis of allergic rhinitis is typically based on the patient's history, physical examination, and response to therapy. Skin testing or allergen-specific IgE blood tests may be used to identify the specific allergens causing the symptoms.

=== Treatment ===

Treatment strategies for allergic rhinitis aim to reduce symptoms by avoiding allergens, using pharmacological therapies, or undergoing immunotherapy. Pharmacological treatments include antihistamines, decongestants, corticosteroid nasal sprays, and leukotriene receptor antagonists. Immunotherapy, such as allergy shots or sublingual tablets, may be an option for individuals with severe symptoms or those who do not respond to other treatments.
