Allergic Rhinitis (Hayfever) Back To Top
Rhinitis is the term used to describe inflammation of the nasal passage. The inflammation can lead to symptoms that include:
-Runny nose -Congestion (stuffiness) of the nasal passage -Nasal itching -Sneezing -Post-nasal drainage -Coughing or throat-clearing -Sinus pressure or headaches -Itchy, red or watery eyes can also occur
Typical allergic triggers include: tree pollen, grass pollen, ragweed pollen, pet dander, mold, and dust mites. A person may have sensitivities to one or more of these allergens.
Other types of rhinitis include
-Non-allergic rhinitis -Infections (viral or bacterial upper respiratory infections) -Chronic sinusitis -Anatomic abnormalities such as a deviated septum or nasal polyps -Less commonly- medications, hormonal fluctuations
It is important to determine what allergies are contributing to a person’s symptoms, as this will allow us to suggest avoidance strategies if possible and to recommend a patient-specific treatment plan.

Eye Allergies Back To Top
Allergies can involve the eyes,
frequently leading to itchy, watery, and red eyes. This is referred
to as allergic conjunctivitis and is often associated with nasal
allergy symptoms. Eye symptoms develop when the allergen (pollen,
pet dander, dust mites, or molds) comes into contact with the lining
of the eyes. Individuals with eye allergies may experience year-round
symptoms but seasonal allergic conjunctivitis from tree,
grass, or ragweed pollen is the most common type of eye allergy.
People with eye allergies may also suffer from dry eyes and irritant
reactions from environmental pollution, cigarette smoke, perfumes, and
over-the-counter eye drops. Determining the things in your environment
that you are allergic to will help the allergist/immunologist create
an appropriate treatment regimen that may include allergy avoidance
strategies, prescription-strength eye drops, antihistamines, and immunotherapy
(allergy shots). |

Food Allergy Back To Top
Up 8% of children, and 2% of adults in the United States develop food allergies. Food allergies develop when a person’s immune system makes an allergy antibody (IgE) to food proteins that are usually tolerated. The allergy may develop even if the person was able to tolerate the food many times in the past. The most common foods that cause allergies are proteins found in cow’s milk, fish, shellfish, peanuts, tree nuts, wheat, and soy.
Symptoms experienced during an allergic food reaction include one or more of the following- hives (red, itchy, and swollen areas of the skin); swelling of the eyes, lips, tongue or throat; abdominal pain, diarrhea, or vomiting; and wheezing or shortness-of-breath. These symptoms typically develop within several minutes to two hours following ingestion of the allergic food.
Approximately one third of infants and toddlers with more severe eczema (atopic dermatitis) may have a food allergy making their rash worse.
Some individuals will experience severe symptoms after eating a food they are allergic to. This is called food-induced anaphylaxis and can be life-threatening. Symptoms include severe wheezing, a large drop in blood pressure, swelling of the tongue or throat, and a feeling of warmth or flushing. In these cases, the allergic reaction is treated with injectable epinephrine, antihistamines, and other emergency medications. Anyone who experiences these symptoms should call 911 immediately.
Diagnosing a food allergy requires a very careful and detailed history- typically by a well-qualified allergist and immunologist. Allergy tests are often used to aid in the diagnosis. Skin testing to the foods in question is typically the most helpful initial test. Blood tests can also be useful in some situations in addition to the skin testing.
Currently, there is no treatment for food allergies other than avoiding the food. It is essential to carry injectable epinephrine in case of a more severe reaction. Careful reading of food labels is also crucial in order to avoid accidental ingestion.
In order to receive an accurate diagnosis and treatment plan, it is important to see a board-certified allergist and immunologist if you or a family member is experiencing symptoms suggestive of a food allergy.

Sinusitis Back To Top
Sinusitis is an inflammatory
condition of one or more nasal sinuses- hollow cavities within the cheek-bones
and behind the forehead. Sinuses drain from a narrow opening that
opens into the nasal passage. Many factors can lead to narrowing
of the drainage points that can result in a sinus infection. Allergic
inflammation is one of the most common causes and is typically triggered
by pollen, pet allergies, dust mites, and molds. Other common
predisposing causes include viral respiratory infections and certain
anatomic abnormalities of the nasal passage.
Symptoms of a sinus infection
include nasal congestion, discolored nasal drainage, bad-tasting post-nasal
drip, coughing, and sinus pressure and headaches. Infections may
be acute or chronic, sometimes lasting for many years prior to diagnosis
and treatment.
Appropriate treatment consists
of proper selection of an antibiotic and other medications used to decrease
the inflammation of the nasal passage and sinuses. An allergist/immunologist
will take a complete history and determine which allergies may be contributing
to your sinus infections and design a specific treatment that will help
prevent future infections. Allergy skin testing is a quick and
easy way to find out what allergies are causing your sinus problems. |

Bronchitis Back To Top
Many patients experience recurrent
episodes of coughing following an upper respiratory tract infection.
Although there are many causes of bronchitis, it is typically caused
by a viral infection that leads to temporary inflammation of the airway
leading into the lungs. Less commonly, these episodes may be caused
by a bacterial infection. A patient does not typically develop
a fever and most episodes resolve with anti-inflammatory medications
(like ibuprofen) and nasal decongestants. Bronchitis can also
be seen in patients with asthma and other respiratory allergies.
So if you are experiencing episodes of bronchitis that are frequent
and last longer than a typical cold, an allergist/immunologist can help
determine the cause of the bronchitis and whether allergies are causing
some of your symptoms. |

Eczema (Atopic Dermatitis) Back To Top
Eczema is a common type of rash that affects the face, legs, and arms- most commonly seen in infants and younger children. However, older children and adults may also experience this allergic rash as well. Children with a personal or family history of allergies are more likely to have eczema. Food allergies can sometimes make the more severe cases of eczema worse. Other environmental allergies such as dust mites, pet allergies, or pollen allergies may also make the rash worse. An allergist/immunologist can help determine what allergies may be making the eczema worse and provide treatment that may include over-the-counter moisturizers, anti-histamines, and prescription topical medications. |

Hives (Urticaria) Back To Top
Hives are red, swollen, itchy areas of the skin. They often look like mosquito bites but may be much larger and are typically round and raised off of the skin. A person often develops many of the bumps at one time all over their body. The hives tend to move around and do not stay in one place very long.
Up to 25% of people experience at least one episode of hives in their lifetime. If hives occur for only a few days or weeks, they are considered acute. Symptoms lasting longer than several weeks are considered chronic. For cases of acute hives, possible causes include a viral infection, food allergy, medications (over-the-counter or prescription), insect allergy, or latex. Acute episodes of hives typically go away on their own. Chronic hives can last for several months or even years. Many cases of chronic hives are caused by an internal immune reaction that leads to histamine release in their skin. A number of people will have symptoms that are triggered by medications, foods, or physical triggers (such as scratching their skin, cold or hot environments, or exercise).
An experienced allergist/immunologist will help identify any possible allergic triggers, order appropriate testing, and design an individual treatment plan that will effectively treat the hives. |

Pet Allergies Back To Top
Cat and dog allergens (unlike
other indoor allergens such as dust mites or cockroaches) consist of
very small particles that remain airborne for long periods of time and
are very sticky to clothing and other surfaces. Because of these
factors, cat and dog dander are found even in places without pets.
For instance, pet dander has been found in school buildings brought
in by children with pets at home. It is for this reason, most
likely, that people can become allergic to dogs or cats without even
having one in their home.
It is not currently known whether
having pets in the home is more likely to make a person allergic to
the pet. But we do know that if a person is allergic to a pet and has
one in the home, their respiratory allergies will most likely be worse.
Pet allergies can cause nasal allergy symptoms as well as asthma symptoms.
An allergist/immunologist can help determine if you are allergic to
your pet and to discuss the many different treatment options for your
pet allergies. |

Stinging Insect Allergy Back To Top
Many people are stung reach
year by insects such as bees, wasps, hornets, and yellow jackets.
Most people only experience swelling, redness, and pain near the place
they were stung. These symptoms may last several hours or more
and are not considered an allergic reaction.
However, some people will develop
an actual allergy to the stinging insect. Like many other types
of allergic reactions, these individual’s will develop an allergy
antibody (IgE) to a protein found in the insect venom.
Symptoms of an insect allergy
are similar to those found with food allergies and include one or more
of the following- hives (red, itchy, and swollen areas of the skin);
swelling of the eyes, lips, tongue or throat; abdominal pain or diarrhea;
and wheezing or shortness-of-breath. Life-threatening reactions
may also develop and include severe wheezing, swelling of the throat
and tongue, a large drop in blood pressure, and feelings of warmth or
flushing. Most insect allergies occur immediately after the insect
sting occurs. However, symptoms may be delayed for up to 1-2 days
after the insect bite occurs in some people.
Anyone who has experienced
a possible insect allergy should be evaluated by an allergist/immunologist,
who will take a complete history, perform appropriate testing, and recommend
a treatment plan designed specifically for you or your family member.
Skin testing is the most accurate way to diagnose insect allergies.
Unlike with food allergies, allergy shots (immunotherapy) are a highly
effective and potentially life-saving treatment option for those who
have more severe insect allergies. It is also important to carry
injectable epinephrine and to call 911 immediately if you experience
symptoms that are suggestive of an anaphylactic reaction to an insect. |
