When to see an Allergist


When to see an Allergist


Often, individuals suffer year after year, with symptoms of asthma or allergies. 

Allergy sufferers may become accustomed to sneezing, nasal congestion or wheezing. However, an allergist can assist in preventing or controlling symptoms thereby dramatically improve one’s quality of life.

Controlling asthma and allergies requires planning, skill and patience. Dr. Erstein, will develop a treatment plan for your specific condition. The goal will be for you to lead a life that is as symptom-free as possible.

You should see an allergist if:

Your allergies or asthma are interfering with your ability to carry out your daily activities.

You experience hay fever or other allergy symptoms a few months out of the year.

Antihistamines and over-the-counter medications do not control your symptoms or if they create side effects, such as drowsiness.

Your asthma or allergies decrease the quality of your life

You are experiencing warning signs of serious asthma such as having to struggle to catch your breath, wheezing or coughing often, especially at night or after exercise, or being frequently short of breath or feeling tightness in your chest.

You have previously been diagnosed with asthma, and despite taking asthma medication, you continue to have frequent asthma attacks.

 

A visit to the allergist might include:

Allergy testing- tests to determine what you are allergic to. These tests may include skin testing or bloodwork. 

Prevention education- An effective approach to treating asthma or allergies is to avoid the factors that trigger your symptoms.  Even when it is not possible to completely avoid allergens, an allergist can help you decrease exposure to allergens.

Immunotherapy-  patients are given injections every week or two of some or all of the allergens that cause their allergic reactions. The doses are slowly increased over time, causing the patient’s immune system to become less and less sensitive to the allergen.  This type of therapy is also called "allergy shots."

Medication prescriptions- A number of new and effective medications are available to treat both asthma and allergies.

Food Challenge- A food challenge is performed when blood tests or skin prick tests don’t offer a clear diagnosis.  Oral food challenges are a common method for ruling out an allergy.

Patient Education


Patient Education


What are allergies?

Allergies are hypersensitive immune responses to substances that either enter or come in contact with the body, such as pollen, pet dander, or bee venom. 

An “allergen” is a substance that causes an allergic reaction. Allergens can be found in food, drinks or the environment. Most allergens are harmless, as the majority of people are not affected by them.

If you are allergic to a substance, your immune system reacts to it as if it were a pathogen (a foreign harmful substance), and tries to destroy it.

What are the signs and symptoms of allergies?

A symptom is something one feels and describes, while a sign can be detected by others too. For example, pain is a symptom and a rash is a sign.

When a person with an allergy comes into contact with an allergen, the allergic reaction may not be immediate. The immune system slowly builds up sensitivity to the substance before overreacting to it.

The immune system needs time to recognize and remember the allergen. As it becomes sensitive to it, it starts making antibodies to attack it - this process is called sensitization.

Sensitization can take a few days to several years. In many cases the sensitization process is not completed and the patient experiences some symptoms but never a full allergy.

When the immune system reacts to an allergen, there is inflammation and irritation. 

Signs and symptoms depend on the type of allergen. 

Allergic reactions may occur in the sinuses, airways, eyes, nasal passages, digestive system, and skin.

Allergic Contact Dermatitis

Allergic contact dermatitis is a type of contact dermatitis that occurs when a patient comes in contact with an irritating substance and has an allergic response.

Gluten Intolerance

Gluten is a protein found in many grains, including barley, rye, and wheat. In people with celiac disease, when gluten is eaten, lasting damage is caused to the lining of the small intestine.

Rhinosinusitis

Rhinosinusitis, commonly referred to as sinusitis, occurs when the sinus openings become blocked or too much mucus builds up causing one or more of the cavities to become inflamed or swollen. Allergic rhinitis or asthma can be associated with chronic sinusitis.

Allergic Rhinitis

Allergic rhinitis is often called allergies or hay fever.  Allergic rhinitis occurs when the immune system overreacts to particles in the air that one breathes.  The immune system attacks the particles (allergens) in the body, causing symptoms such as sneezing and a runny nose

Asthma Care and Treatment


Asthma Care and Treatment


What is Asthma?

Asthma is a chronic disease of the airways that makes breathing difficult. Asthma causes inflammation of the air passages which results in a temporary narrowing of the airways which carry oxygen to the lungs. This leads to asthma symptoms, such as coughing, wheezing, shortness of breath, and chest tightness. When severe, asthma can result in decreased activity and inability to talk. 

With proper asthma treatment, individuals can live well. Inadequate treatment of the disease limits the ability to exercise and be active. Poorly controlled asthma can lead to multiple visits to the emergency room and even hospital admission, which can affect performance at home and work.


There are three major features of asthma:

1. Airway obstruction. During normal breathing, the bands of muscle that surround the airways are relaxed, and air moves freely. But in people with asthma, allergy-causing substances, colds and respiratory viruses, and environmental triggers make the bands of muscle surrounding the airways tighten, and air cannot move freely. Less air causes a person to feel short of breath, and the air moving out through the tightened airways causes a whistling sound known as wheezing.

2. Inflammation. People with asthma have red and swollen bronchial tubes. This inflammation is thought to contribute greatly to the long-term damage that asthma can cause to the lungs. Treating this inflammation is key to managing asthma in the long run.

3. Airway irritability. The airways of people with asthma are extremely sensitive. The airways tend to overreact and narrow due to even the slightest triggers such as pollen, animal dander, dust, or fumes.

Asthma Treatment

There are a number of treatments for Asthma and Allergic Asthma.  Dr. Erstein will evaluate your symptoms and determine a course of treatment tailored to your needs.  A number of treatments are listed below.

1. Rescue Inhalers (Short-Acting Bronchodilators). These work quickly and are usually the first medication used for an asthma attack. Everyone who has asthma should have a short-acting bronchodilator.  They're often called rescue inhalers because they come in a small inhaler that you carry with you and puff when you have symptoms. The effects last 4-6 hours. They work by opening up, or dilating, the airways in your lungs

2. Inhaled Corticosteroids. If your doctor thinks you're using your rescue inhaler too often, that's a sign your asthma isn't under control. You may need to take medications such as inhaled steroids every day.  You inhale these drugs through a portable device. They work by minimizing inflammation in your lungs' airways.  They're called "controller" medications because they help control your asthma over longer periods of time. These medications can help keep your lungs working better after future asthma attacks. You probably won't need your rescue inhaler as much either.

3. Long-Acting Bronchodilators. Long-acting bronchodilators are another type of controller medication. They work like rescue inhalers, but the effects last longer, usually about 12 hours. You use them regularly, twice a day.  You should only use them along with inhaled steroids, not ever as the only medication to control your asthma.

4. Anti-Leukotriene Drugs. These are pills that help with long-term asthma control.These drugs shut down the effects of molecules called leukotrienes, which trigger airway inflammation.

5. Oral Corticosteroids. Prednisone is a common steroid used by people whose rescue inhaler doesn't help enough when they have a severe asthma attack. It's usually taken as a pill. It works by lessening the inflammation that causes the serious symptoms. You should use steroids only when you need them, because they can cause serious side effects if you take high doses for a long time.

6. Antibody Treatment. This is usually a last-resort medication for people with severe asthma that doesn't go away and isn't controlled with other treatments. It prevents cells in your body from starting the inflammation process and makes you less sensitive to your triggers. It's given as an injection every 2 or 4 weeks at your doctor's office, because you might have a severe allergic reaction to it. It doesn't often cause other side effects, but it is expensive.
