Allergies affect millions of individuals, causing various symptoms. For those experiencing persistent or severe allergic reactions, a medical doctor specializing in allergies can provide focused care. These specialists possess training to understand the body’s immune responses that cause allergic symptoms and to develop tailored management plans.
Who They Are and What They Do
A medical doctor who specializes in treating allergies is known as an allergist or an allergist-immunologist. These physicians complete medical school, followed by a residency in internal medicine or pediatrics, and then undertake two to three additional years of specialized training in allergy and immunology. This education prepares them to diagnose, treat, and manage allergic diseases and certain disorders of the immune system.
Their work involves identifying substances that trigger allergic reactions and developing strategies to help patients manage their conditions. They aim to improve quality of life by controlling symptoms and preventing severe reactions. Allergists work with both adults and children to address their allergic and immunological health needs.
Conditions They Manage
Allergist-immunologists treat a broad spectrum of conditions where the immune system overreacts to harmless substances, known as allergens. They manage allergic rhinitis, known as hay fever, which can cause symptoms like sneezing, nasal congestion, and itchy eyes, either seasonally or year-round. Skin allergies, such as eczema (atopic dermatitis) and hives (urticaria), also fall under their expertise.
These specialists also treat food allergies, where even tiny amounts of certain foods can trigger reactions. They also address drug allergies and insect sting allergies, which can lead to severe, body-wide reactions. Asthma, a condition affecting the airways and making breathing difficult, is another area of their practice, especially when it is allergy-induced. Allergists also handle recurrent sinus infections and primary immunodeficiency disorders.
When to Seek Their Care
Consulting an allergist is advisable if allergic symptoms are persistent, severe, or significantly interfere with daily life. If over-the-counter medications are no longer effective or cause unwanted side effects, specialized evaluation is beneficial. Chronic symptoms such as ongoing nasal congestion, frequent sneezing, or difficulty breathing that last for more than a few months warrant a visit.
Individuals experiencing frequent sinus infections or ear infections should see an allergist, as these can be linked to underlying allergies. A visit is also recommended for those who have had a severe allergic reaction, such as anaphylaxis, which can involve throat swelling, wheezing, or a drop in blood pressure. If allergies or asthma negatively impact work, school, sleep, or overall quality of life, an allergist can provide tailored solutions.
Diagnostic Methods and Treatment Approaches
To identify specific triggers, allergists employ various diagnostic methods. The skin prick test is a common approach where small amounts of potential allergens are applied to the skin. A positive reaction, indicated by a raised bump or hive, appears within 15 minutes.
Blood tests, specifically IgE antibody tests, measure the immune system’s response to particular allergens by detecting immunoglobulin E antibodies in the blood. These tests are useful when skin testing is not suitable, such as due to skin conditions or certain medications.
Supervised challenge tests may also be performed, where a patient consumes or inhales a small amount of a suspected allergen under close medical observation.
Treatment approaches begin with allergen avoidance strategies, where patients learn to minimize exposure to their identified triggers. Medication management is another key treatment approach and may include antihistamines to block histamine, nasal corticosteroids to reduce inflammation, and bronchodilators for asthma symptoms.
For severe allergies or those not responding to other treatments, immunotherapy may be recommended. This involves gradually exposing the immune system to increasing doses of allergens over time, through allergy shots or sublingual tablets. Immunotherapy works by training the immune system to become less reactive, leading to long-term tolerance and a reduction in allergic symptoms.
