Where does rhinitis come from?

Question

please help me to answer this question for my report

Answer 1

Rhinitis is the medical term describing irritation and inflammation of the nose. The primary symptom of rhinitis is a runny nose. It is caused by chronic or acute inflammation of the mucous membrane of the nose due to viruses, bacteria or irritants. The inflammation results in excessive mucous production producing a runny nose, nasal congestion and post-nasal drip.

Rhinitis is caused by an increase in histamine. This increase is likely caused by airbourne allergens. These allergens may affect an individual's nose, throat, or eyes and cause an increase in fluid production within these areas.

There are two types of Rhinitis that the general population may suffer from. Those types include Allergic Rhinitis and Nonallergic Rhinitis.

Rhinitis is one of the most common illnesses in the United States , affecting more than 50 million people. It often coexists with other respiratory disorders, such as asthma. Rhinitis has a significant impact on the quality of life of those who suffer from it. In addition, it can contribute to other conditions such as sinus problems, ear problems, sleep problems, and learning problems. In patients with asthma, uncontrolled rhinitis seems to make asthma worse.

There are two general types of rhinitis:

Allergic rhinitis
Allergic rhinitis is caused by substances that we breathe called allergens. Allergens are usually harmless substances that can cause problems only in some people. These problems are caused because the immune system of people with allergic rhinitis mistakenly identifies these substances as intruders and generates a reaction against them. During this reaction, the immune system cells release substances such as histamine and leukotrienes that cause the symptoms of allergic rhinitis; these and other substances also cause inflammation in the nasal lining that makes the nose very sensitive to irritants such as smoke and strong odors or to changes in the temperature and humidity of the air.

Causes

When allergic rhinitis is caused by common outdoor allergens, such as airborne tree, grass and weed pollens or mold, it is called seasonal allergic rhinitis, or “hay fever.”

Allergic rhinitis is also triggered by common indoor allergens, such as animal dander (dried skin flakes and saliva), indoor mold, droppings from dust mites and cockroach particles. This is called perennial allergic rhinitis.
Symptoms

Sneezing

Stuffy nose (congestion)
Runny nose
Itching in the nose, roof of the mouth, throat, eyes and ears
Diagnosis
If you have symptoms of allergic rhinitis, an allergist/immunologist can help determine which specific allergens are triggering your illness. He or she will take a thorough health history, and then test use to determine if you have allergies. Skin tests or blood tests are the most common methods for determining your allergic rhinitis triggers.

Treatment
Once your allergic rhinitis triggers are determined, your physician or nurse will work with you to develop a plan to avoid the allergens that trigger your symptoms. For example, if you are allergic to dust mites or indoor mold, you will want to take steps to reduce these allergens in your house as much as possible. The Tips brochures on Indoor Allergens and Outdoor Allergens provide helpful advice in this area.
