Allergic rhinitis is a medical disorder of allergic effects affecting the nose.
These allergic conditions occur when the patient breathes in something he or she is allergic to such as dust, animal dander or pollen.
Symptoms can also happen when the patient eats a food that he or she is allergic to.
Most allergic rhinitis disorders are due to plant pollens.
This form of allergic rhinitis is often called hay fever or seasonal allergy.
An allergen is something that activates an allergy reaction.
Hay fever is an allergic response to pollen.
Plants that produce a hay fever reaction are trees, flowering plants, grasses and weeds.
The pollen from the plants is transmitted by the wind.

Allergy testing may show the pollen or other substances that trigger the symptoms.

2. If the doctor finds that the patient cannot have skin testing, special blood tests may help with the diagnosis.
3. The tests are known as IgE RAST tests and can measure the levels of allergy-related substances.
4. A full blood count (FBC) test involving the eosinophil count
Treatments for allergic rhinitis are:
Antihistamines

Decongestants
Leukotriene inhibitors
Allergy shots (immunotherapy)

Allergic Rhinitis is a very common condition in all ages.
Some childhood Vasomotor Rhinitis improves after puberty.
Others go on to adulthood.
The most obvious symptom is sneezing or stuffy nose every morning which slowly improves by late morning.
Allergic Rhinitis may result in chronic sinusitis due to chronic nasal infections.
