Rhinitis is when a reaction occurs that causes a stuffy nose, runny nose, sneezing, and itching. Most types of rhinitis are caused by inflammation and lead to symptoms in the eyes, ears, or throat. There are several types of rhinitis. The most common types of rhinitis are:

• Acute rhinitis, which is often caused by a viral illness
• Allergic rhinitis (can be seasonal or year-round)
• Nonallergic rhinitis

Allergic rhinitis is caused when allergens in the air trigger the release of histamine in the nose and sinuses. Histamine causes itching, swelling, and fluid to build up in the fragile linings of the nasal passages, sinuses, and eyelids.

The most common causes of rhinitis are:

• Pollen given off by trees, grass, and weeds
• Dust mites
• Mold
• Cockroach waste
• Animal dander
• Fumes and odors
• Extreme temperature or changes in temperature
• Hormonal changes
• Certain medicines and overuse of topical nose sprays
• Changes in the environment
• Irritants, such as strong odors and tobacco smoke
• Certain foods or spices

People with asthma are at a higher risk for rhinitis. Allergic rhinitis is a common problem that may be linked to asthma. But this link is not fully understood. Experts think that since rhinitis makes it hard to breathe through the nose, it's harder for the nose to work normally. Breathing through the mouth does not warm, filter, or humidify the air before it enters the lungs. This can make asthma symptoms worse.

Asthma and allergies are also caused by many of the same chemical triggers in the body.

Controlling allergic rhinitis may help control asthma in some people.

Symptoms of rhinitis include:

• Sneezing.
• Stuffy nose.
• Runny nose.
• Itchy nose, throat, eyes, and ears.
• Nosebleeds.
• Clear drainage from the nose.
• Ear infections that keep coming back.
• Snoring.
• Breathing through the mouth.

Most often, the diagnosis is made by your doctor based on a full health history and physical exam. In addition to the above signs, the doctor may find:

• Dark circles under the eyes (more common in children).
• Creases under the eyes.
• Swollen tissues inside the nose.
• Mouth breathing.

Staying away from the allergens that are causing the problem is the best treatment. Sometimes it can be hard to stay away from triggers (including allergens), such as pollens. The symptoms of rhinitis sometimes look like other conditions or health problems. Always see your doctor for a diagnosis.

Treatments for rhinitis may include:

• Antihistamines.
• Nose sprays.
• Decongestants.
• Medicines for asthma symptoms.
• Allergy shots.
• Surgery for some health problems.

Preventive measures depend on what triggers your rhinitis. These can include:

• Staying away from areas where there is heavy dust, or mold.
• Not being around pets.
• Staying away from what you know you are allergic to, or what triggers your symptoms.
• Controls in your environment, such as air conditioning during pollen season.
• Staying away from people who are smoking.
• Staying away from strong odors and irritants when possible.
• Using nose sprays only for the prescribed length of time.

• Allergic rhinitis is a reaction that happens in the eyes, nose, and throat when allergens in the air trigger histamine to be released in the body.
• Some of the most common causes of allergic rhinitis are pollen, dust mites, mold, cockroach waste, and animal dander.
• Nonallergic rhinitis is inflammation in the nose, eyes, and throat from nonallergic sources, such as fumes and odors, hormonal changes, and smoke.
• Symptoms of rhinitis include sneezing, stuffy and runny nose, nosebleeds, and itchy throat, eyes, and ears.
• Treatment may include medicines, allergy shots, and surgery for some health problems.
• Preventive measures for rhinitis include staying away from what you are allergic to and other triggers.
