What is an allergy?

The human body can defend itself from external intruders like viruses or bacteria. However, occasionally, the immunity becomes overly active, identifying harmless environmental triggers as toxic, such as dust, mold, or pollen. The immune system activates its defenses, namely the white blood cells, which trigger an allergic reaction. The allergic response aims to eliminate the foreign substance (allergen) from the body. Allergic reactions can manifest with varying degrees of severity, ranging from mild symptoms like itching to more severe conditions like anaphylaxis.

Who is an allergist?

An allergist, or an immunologist, is a medical specialist with special training in detecting, treating, and managing allergies. An allergist also treats breathing problems and immunologic diseases, such as primary immunodeficiency abnormalities. These illnesses affect people of all ages, impact different organ systems, and range in severity. There is no better option than visiting an allergy expert to treat your allergies. 

An allergist must complete three to four years of study in pediatrics or internal medicine in addition to their traditional medical education, including a bachelor's degree and graduation from medical school. All applicants must finish two years of specialized allergy and immunology training to be certified by the American Board of Allergy and Immunology. 

What does an allergist do?

The key responsibilities of an allergist are:  

• Conducting allergy tests: They perform tests to pinpoint allergies to triggers such as foods, pollen (e.g., grass, trees, weeds), pet dander, mold, and other substances. 
• Diagnosing immunodeficiency disorders: Allergists may suggest HIV tests, protein electrophoresis (blood or urine), and examinations to check immunoglobulin levels in the blood, T (thymus-derived) lymphocyte count, and White blood cell count, among other things, to diagnose immunodeficiency disorders.  
• Providing IVIG treatment: They may offer intravenous immunoglobulin (IVIG) treatment tailored to specific immune disorders.  
• Assessing lung function and asthma diagnoses: Allergists evaluate lung function and diagnose asthma.
• Prescribing medications and devices: They prescribe medications or devices designed to prevent, treat, or alleviate the severity of allergic reactions and asthma attacks.  
• Guiding on lifestyle adjustments: Allergists offer guidance on lifestyle adjustments to minimize exposure to triggers for asthma and allergies.  
• Conducting drug desensitization: Allergists perform drug desensitization procedures, enabling the safe use of essential medications in individuals with allergies.

Different types of allergies

An allergic response can happen anywhere in the body, but it often affects the skin, nose, eyes, lungs, sinuses, and throat. These sites are where the environmental irritants first enter the body. The specialized immune system cells are activated here to safeguard against intruders that are either eaten, inhaled, or in contact with the skin.

• Allergic rhinitis (hay fever): Allergic rhinitis is a broad term that describes allergic responses affecting the nose. Sneezing, persistent nasal congestion, and itching of the eyes, nose, and roof of the mouth can all be symptoms. The condition is also known as 'hay fever' when it occurs during the spring, summer, or fall and is triggered by pollens or environmental molds.
• Asthma: Inflammation of the bronchial tube linings and airway muscle spasms obstructing airflow to the lungs are two causes of asthma symptoms. Mucus build-up can also block the airways. Coughing or wheezing are signs of an asthma attack, difficulty or restricted breathing, tightness in the chest, and nasal flaring. Generally, the only symptom may be a persistent cough. Asthma symptoms range from mild discomfort to potentially fatal episodes in which breathing stops altogether.
• Hives, skin allergies, and atopic dermatitis: Allergies and other irritants can manifest as skin diseases, too, including eczema, hives, and atopic and contact dermatitis. As with poison ivy, the response can take quite some time to manifest. The most typical allergic triggers for skin rashes include medications, insect bites, foods, animals, and household or occupational pollutants. Emotional stress may also exacerbate allergies.
• Anaphylaxis: A rare, potentially lethal allergic reaction known as anaphylaxis affects all bodily systems simultaneously. An insect bite, food allergen —like peanuts—or a drug can potentiate it. Some signs are vomiting, diarrhea, a hazardous drop in blood pressure, hives or skin rash, breathing difficulty, throat or tongue swelling, and loss of consciousness. These symptoms often appear suddenly and worsen quickly.
• Food allergies: Another allergic reaction is a response to dietary components. It's seen in lactose-intolerant individuals or those with gluten allergies. Symptoms include persistent diarrhea, weight loss, and multiple vitamin deficiencies. 

Which parts of the body are generally prone to allergic reactions?

Allergens cause different symptoms depending on the entry point. Reactions to them can affect many parts of the body simultaneously. Commonly affected areas include:  

• Chest and lungs: Inhaling allergens may lead to swollen lung walls and asthma symptoms. These can range from chest tightness and labored breathing to coughing and wheezing, with potential life-threatening severity.  
• Eyes, nose, throat, and sinuses: When allergens enter the body, they trigger histamine release, causing inflamed nasal passages and excessive mucus production. Symptoms may include an itchy, runny nose, frequent sneezing, watery eyes, and a sore throat. Persistent symptoms throughout the year may indicate indoor allergens like dust mites, pets, or molds.  
• Stomach and bowel: Allergic reactions to certain foods like seafood, dairy, peanuts, and eggs can lead to various gastrointestinal issues. Infants may experience eczema, colic pain, or stomach upset due to an allergy to cow's milk. Lactose intolerance differs from dairy allergy since it is an immune system disorder.  
• Skin: Skin allergies manifest as eczema (atopic dermatitis) or hives (urticaria). Causes include exposure to medicines, foods, animals, chemicals, or insect bites. Skin allergies may have delayed reactions, and emotional imbalances can exacerbate symptoms.

Understanding these diverse manifestations of allergic reactions in different body parts is crucial for accurate diagnosis and effective management.

How are the patients tested and treated for allergies?

The allergist collaborates with patients to diagnose and manage immunological disorders. They review the patient's medical history and perform several tests to arrive at the correct diagnosis.

• Skin tests diagnose food, insect, and environmental allergies. Small doses of the allergens are injected within the superficial layer of the skin. After one to two hours, the allergic response to each allergen is checked. The formation of a red flare around the injected site indicates an allergy to that particular trigger. 
• Blood tests, such as eosinophil (white blood cell) and IgE levels, show an ongoing allergic response. They help diagnose and prognosis such patients. 
• Lung function tests detect asthma or other respiratory conditions. Asthma is also commonly triggered by allergens and needs regular lung function monitoring to prevent any fatal asthma attacks in the future. 
• Treatment of allergies generally requires oral medication. Your allergist will understand the symptoms and response and determine the best medicine and dosage for you. Decongestants and antihistamines are the two most commonly used allergy medications. In cases of asthma, inhaled corticosteroids prove handy for the acute management of symptoms. 
• Another mode of treatment called immunotherapy focuses on building up the body's tolerance to a particular allergen. The therapy entails giving the patient minute doses of that specific allergen, which are slowly and progressively increased. By producing blocking antibodies over time, the immune system becomes more adept at combating allergies without having an exaggerated reaction or symptoms.

Asthma: symptoms, types, and treatment

Asthma is a chronic condition affecting the lung's airways. These bronchial tubes, also known as airways, allow air to enter and exit the lungs. Your airways are always inflamed if you have asthma. When something triggers your symptoms, they swell even more, and the muscles surrounding the airways may become tight. It makes it challenging for air to enter and exit the lungs, which results in symptoms like shortness of breath, coughing, wheezing, and tightness in the chest.

The timing of these symptoms mostly depends upon physical activity for many people with asthma. Additionally, some otherwise healthy individuals may only experience asthma symptoms when exercising. It is called exercise-induced bronchoconstriction (EIB) or exercise-induced asthma (EIA). Since exercise is critical to maintaining good health, asthma shouldn't prevent you from participating in sports. To keep your symptoms under control before, during, and after physical activity, your doctor can create a treatment plan for you accordingly.

Individuals with a family history of asthma or allergies are likelier to develop asthma. Numerous asthmatics also have allergies. This condition is known as allergic asthma. In comparison, occupational asthma is caused by inhaling dust, gas, fumes, or other potentially harmful substances while on the job. Childhood asthma has a tremendous effect on millions of kids and their families. Most children with asthma are usually diagnosed with it when they are five or younger.

Although there is no known cure for asthma, it is manageable with a proper diagnosis and treatment plan. People with asthma can learn to manage episodes and use their prescribed medication to prevent or relieve their symptoms. Additionally, they can learn to identify and stay away from the triggers of an attack. Most asthmatics can take control of their condition and lead active lives by educating themselves on managing their medications and other asthma management techniques.

Planning, skill, and patience are necessary to manage asthma and allergies effectively. The allergist will devise a treatment plan for your ailments accordingly. The focus of your treatment would be that you should lead a symptom-free life.
