Rhinitis…Also Known As Nasal Allergies

What Is Rhinitis?

The word rhinitis means “inflammation of the nose.” The nose produces a fluid called mucus. This fluid is normally thin and clear. It helps to keep dust, debris, and allergens out of the lungs. Mucus traps particles like dust and pollen, as well as bacteria and viruses.

Mucus usually drains down the back of your throat. You’re not aware of this most of the time because it is a small amount and is thin. When the nose becomes irritated, it may produce more mucus, which becomes thick and pale yellow. The mucus may begin to flow from the front of the nose as well as the back. Substances in the mucus may irritate the back of the throat and cause coughing. Postnasal drip occurs when more mucus drains down the back of the throat.

What Causes Rhinitis?

Irritants or allergens may cause rhinitis. The cells of your body react to these irritants or allergens by releasing histamine and other chemicals. Rhinitis is often a temporary condition. It clears up on its own after a few days for many people. In others, especially those with allergies, rhinitis can be a chronic problem lasting weeks or months while exposure continues. 

What Are the Types of Rhinitis?

There are several types of rhinitis with the most common being:

• Allergic rhinitis is caused by allergies to substances called allergens. 
• Seasonal allergic rhinitis is sometimes called “hay fever.” But, people with seasonal allergic rhinitis do not have to have a fever and do not have to be exposed to hay to develop this condition. It is an allergic reaction to pollen from trees, grasses and weeds. This type of rhinitis occurs mainly in the spring and fall, when pollen from trees, grasses and weeds are in the air.
• Perennial allergic rhinitis is caused by allergens that are present all year long. The primary causes of this type of rhinitis are allergies to dust mites, mold, animal dander and cockroach debris.
•  Non-allergic rhinitis is not caused by allergens. Smoke, chemicals or other irritating environmental conditions may provoke non-allergic rhinitis. Hormonal changes, physical defects of the nose (like a deviated septum) and the overuse of decongestant nose sprays may also cause it or as a side effect to a medication,
• Infectious rhinitis is possibly the most common type of rhinitis. It is also known as the common cold or upper respiratory infection (URI). Colds occur when a cold virus settles into the mucous membranes of the nose and sinus cavities and causes an infection.

What Are the Symptoms of Rhinitis?

Rhinitis symptoms include:

• Itching in the nose and eyes
• Sneezing
• Stuffy nose (congestion)
• Runny nose
• Mucus (phlegm) in the throat (postnasal drip)

Cold or Allergy?

Sometimes it can be hard to tell the difference between allergies and the common cold. There are more than a hundred strains of cold viruses. Each tends to become widespread at certain times of the year, which is why you may mistake a cold for a seasonal allergy. Allergies occur at the same time every year and last as long as the allergen is in the air (usually 2-3 weeks per allergen). Allergies cause itching of the nose and eyes along with other nasal symptoms. Colds last about one week and have less itching of the nose and eyes.

What Are the Treatments for Allergic Rhinitis?

The first and best option is to avoid contact with substances that trigger your nasal allergies (allergens). When prevention is not enough, consider using over-the-counter or prescription medicines:

• Antihistamines are taken by mouth or as a nasal spray. They can relieve sneezing and itching in the nose and eyes. They also reduce a runny nose and, to a lesser extent, nasal stuffiness. There are many classes of antihistamines. If one doesn't seem to help, perhaps try a different "class". If one has stopped working, take a holiday from that class and switch to another.
• Decongestants are taken by mouth or as a nasal spray or drops. They help shrink the lining of the nasal passages which relieves nasal stuffiness. These nose drops and sprays should be taken short-term.
• Nasal corticosteroids are used in nasal spray form. They reduce inflammation in the nose and block allergic reactions. They are the most effective medicine type for allergic rhinitis because they can reduce all symptoms, including nasal congestion. Nasal corticosteroids have few side effects but do require a prescription.
• Leukotriene receptor antagonists block the action of important chemical messengers other than histamine that are involved in allergic reactions (require a prescription)
• Cromolyn sodium is a nasal spray that blocks the release of chemicals that cause allergy symptoms, including histamine and leukotrienes. This medicine has few side effects, but you must take it four times a day.
