Have you ever sneezed yourself out of control when the spring blooms are in? Or are you getting an itchy rash on your skin after some new lotion? There is perhaps some food you find aversive. In that case, you have had an allergy. Allergies are considered to be one of the most widespread chronic diseases in the world, impacting millions of people of all ages.

In this guide, we have extensively discussed allergies, its different forms, possible causes, most likely symptoms and how it can be managed and prevented. We aim to provide you with general information and make you knowledgeable about the discussions and communication with medical workers.

 

What is an Allergy?

In a few words, an allergy is a response by your immune system to something that would otherwise not cause any harm to most of the population. They are called allergens.

The immune system is your bodies well trained security detail. It is tasked with the responsibility of detecting and damaging bad intruders such as viruses and bacteria. This security system will unintentionally cause an allergy trigger in a person who has an allergy, who will perceive a harmless substance, such as pollen, pet dander, or a certain food item, as a threat. This causes a defensive reaction which we manifest as allergic.

This is a response that sees production of antibodies known as Immunoglobulin E (IgE). Histamine is the first chemical to be released in the blood by these antibodies. The discharge of histamine and other chemicals is the cause of the inflammation and typical symptoms of an allergic reaction.

Common Types of Allergies

There are several ways in which allergies can be classified depending on the type of allergen and your contact with it. The most common ones are:

 

1. Respiratory Allergies (Inhalant Allergies)

These are activated by air allergens which you inhale.

·       Pollen Allergy (Hay Fever or Allergic Rhinitis): Pollen of the trees, grasses, and weeds is the cause. It is often seasonal.

·       Dust Mite Allergy: the microscopic insects are triggered by dust residing in the house especially on the bedding, upholstered furniture and carpets.

·       Mold Allergy: This is brought about by the spores of domestic and outdoor molds.

·       Pet Dander Allergy: This is caused by proteins present in the skin flakes, saliva, and urine of furry pets such as cats and dogs.

 

2. Food Allergies

These happen when the immunity responds to certain proteins in food. Widely known food allergens:

·       Milk

·       Eggs

·       Peanuts

·       Nuts (almonds, cashews, walnuts, tree nuts)

·       Soy

·       Wheat

·       Fish

·       Shellfish

One should identify the differences between a food allergic reaction and a food intolerance, which does not require the immune system and is usually not severe.

 

3. Skin Allergies

They happen when an allergen is exposed to the skin.

·       Atopic Dermatitis (Eczema): This is a chronic condition typically linked to allergy that leads to a scaly, scratchy and swollen skin.

·       Contact Dermatitis: A response that is manifested when skin is exposed to an allergen, including:

o   Nickel (in belt buckles)

o   Smell (in perfumes, soaps, cosmetics)

o   Latex (in gloves, balloons)

o   Poison Ivy or Poison Oak

 

4. Insect Sting Allergies

Due to venom that has been injected by stings or bites.

·       Bees

·       Wasps

·       Hornets

·       Yellow jackets

·       Fire ants

 

5. Drug Allergies

A side effect to a drug. Common triggers include:

·       Antibiotics such as penicillin.

·       Sulfa drugs

·       Anti-inflammatory medicines such as aspirin and ibuprofen that are not steroidal (NSAIDs).

·       Anticonvulsants

Potential Causes and Risk Factors

It is still not known why certain individuals become allergic and others do not. It is, however, thought to be genetic and environmental.

·       Genetics: Atopy or a propensity to allergies tends to be familial. When either or both parents rely on allergies, the children will be more likely to inherit the same.

·       Environment: It can be caused by exposure to allergens at particular times when the body defenses are weak or underdeveloped (e.g. during childhood). According to the Hygiene Hypothesis, immunity to harmful substances may fail to develop due to living in excessively clean environments, which may lead to a higher risk of allergic diseases.

·       Other Factors: Factors such as air pollution, tobacco smoke and even some infections are also being studied to determine whether they also play any role in the development of allergies.

 

Recognizing the Symptoms: From Mild to Severe

Allergy may be mild and irritating or severe and fatal. The symptoms may concern different body areas.

Characteristic Mild and moderate symptoms:

·       Respiratory System: sneezing, runny/stuffy nose, cough, wheezing, shortness of breath.

·       Vision: Runny, scratchy, reddish eyes (allergic conjunctivitis).

·       Skin: Itchiness, erythema, hives (raised itchy welts), eczema.

·       Digestive: nausea, vomiting, stomach cramps, diarrhea (universal with food allergies).

Anaphylaxis revealed by symptoms:

Anaphylaxis is a severe, life-threatening, whole-body allergic response that is usually an emergency. Symptoms may arise quite quickly, and they include:

·       Narrowing and constriction of the airways.

·       Throat swelling or a throat lump that causes a difficulty in breathing.

·       A drastic fall of blood pressure (shock).

·       Rapid, weak pulse

·       Lightheadedness, dizziness or unconsciousness.

Anaphylaxis is a psychological emergency. In case somebody suspects that it is happening to them, call emergency.

 

Practical Strategies for Management and Prevention

Although there is no exact cure of an allergy, there are many ways to deal successfully with the symptoms and avoid the allergic reaction.

1. Allergen Avoidance (The First Line of Defense)

The best approach to the prevention of an allergic reaction is to avoid the allergen.

·       Pollen: check the pollen forecasts and do not go outside when the pollen is high. Close the windows and use air conditioning. Take a shower and change clothes after outside.

·       In the case of Dust Mites: Mattress and pillow covers as well should be allergen-proof. Laundry every one week in hot water. Reduce indoor humidity. Vacuum every now and then using the HEPA filter vacuum.

·       In the case of Pet Dander: Do not allow pets in the bedroom and on the furniture. Bathe pets regularly.

·       Fix leaks and damp places: Clean up Mold. Install a dehumidifier in basements and in humid areas.

·       In the case of Food Allergies: Read food labels carefully. Notify restaurant personnel of your allergy. Discover how cross-contamination can occur when preparing food.

2. Over the Counter (OTC) and Prescription Treatments

Different drugs are useful in alleviating symptoms of allergy.

·       Antihistamines: Prevent the action of histamine, and relieve sneezing, itching and a running nose.

·       Decongestants: Interim congestion of the nose.

·       Nasal Corticosteroid Sprays: Decrease inflammation and are said to be one of the most effective forms of treating allergic rhinitis.

·       Eye Drops: It may relieve watery eyes.

·       Topical Creams: Corticosteroid creams, etc., may help decrease inflammation and itching of the skin.

Before taking any new medicine, it is necessary to consult the pharmacist or healthcare provider so that they can ascertain that a new medicine is suitable to you.

3. Consultation and Testing

A medical worker can help in the event that you are allergic, which you suspect.

·       They have an opportunity to examine your history and symptoms.

·       They may recommend a test, such as a skin prick test, or a blood test (specific IgE test) to help determine specific allergens.

4. Emergency Preparedness

In people who have had a severe reaction history:

·       This device is very important and must be carried everywhere and properly used.

·       Make sure your family, friends, and the people you work with know about your allergy, and how to handle it in an emergency.

·       An epinephrine auto-injector (EpiPen®) can be prescribed by a health professional.

Frequently Asked Questions (FAQs)

 

Q1: Could you become allergic as an adult when as a child you never have allergies?

A: Yes, one can get new allergies at any age of life. Although some of these allergies are acquired during childhood, allergies in adults are widespread. The reasons are not entirely clear but may be associated with environmental and body system change, or new allergens.

 

Q2: What is the difference between the food intolerance and food allergy?

A: A food allergy is an immune system event that may lead to various symptoms including serious and life-threatening conditions such as anaphylaxis. Food intolerance, including lactose intolerance, usually includes the digestive tract and develops when the body cannot adequately digest a particular food. The intolerance symptoms (e.g. gas, bloating, diarrhea) tend to be mild, and are often restricted to digestive issues.

 

Q3: Are there any natural remedies of allergy?

A: Others investigate natural methods, such as nasal saline rinses to clear allergens, an air purifier with a HEPA filter, or local honey (but there is not much scientific data on whether honey works). Before attempting to use any natural remedies, it is important to consult with a medical expert because they are not regulated and can have interactions with other treatments and are ineffective.

 

Q4: Can allergies be outgrown?

A: Outgrowth: It is common in childhood to develop outgrowth of some allergies especially to milk, eggs, soy, and wheat. But allergies to peanuts, tree nuts, fish, shellfish tend to be life-long. Potential to outgrow an allergy is not universal and it must be determined by an allergist using the correct testing.

 

Q5: How will I know whether my symptoms are caused by a cold, or allergies?

A: A cold and allergies may have similar symptoms (sneezing, congestion). Key differences include:

·       Duration A cold typically takes 7-10 days. The symptoms of allergy do not disappear until you are out of contact with the allergen.

·       The onset: The manifestation of allergy starts immediately after contact with an allergen. Cold symptoms develop several days after the exposure to a virus.

·       Symptoms: Symptoms of allergies are itchy eyes and throat, rather than the cold. Colds are likely to lead to body aches, fever, and sore throat.

 

Q6: What should I do when there is a serious allergic reaction?

A: In case of symptoms of anaphylaxis (e.g. difficulty breathing, swollen throat, extreme dizziness), administer an epinephrine auto-injector (provided that it has been prescribed) and immediately call an ambulance. Do not put off emergency treatment.
