What is Allergy<\/strong><\/h2>\n\n\n\n

Allergy, in simple terms, is an overreaction of the immune system to substances that are usually harmless.<\/a> These substances, known as allergens, can trigger an allergic reaction when they come into contact with the body. While most people can tolerate these allergens without any adverse effects, individuals with allergies may experience a range of symptoms instead.<\/p>\n\n\n\n

It is important to note that symptoms of an allergic reaction can manifest in various forms, such as shortness of breath, skin rashes, nasal congestion or stuffy nose<\/a>, digestive issues<\/a>, and even life-threatening anaphylaxis. Although, take note that severe allergic reactions can vary from person to person. Some people may experience mild symptoms while others face more severe consequences.<\/p>\n\n\n\n

Furthermore, allergies can develop at any stage of life, not just in childhood as commonly believed. It is possible for adults to develop new allergies or for existing allergies to change over time. This highlights the dynamic nature of allergies and the importance of staying vigilant about potential allergens, even if no previous allergic reactions have occurred.<\/p>\n\n\n\n

Role of Immune System in Allergy Occurrence<\/strong><\/h3>\n\n\n\n

At the core of allergies is the body’s immune system. The immune system’s primary function is to protect the body from harmful substances, such as bacteria and viruses. However, in individuals with allergies, the immune system mistakenly identifies allergens as threats and launches an attack.<\/p>\n\n\n\n

The immune system sets off antibodies that fight off allergens. These antibodies are known as Immunoglobulin E, which release certain chemicals that can result in an allergic reaction or allergy symptoms.<\/a><\/p>\n\n\n\n

Different Types of Allergies<\/strong><\/h2>\n\n\n\n

As mentioned, various kinds of allergies can manifest at any age or lifetime. Understanding the different types of allergies can help individuals identify their specific triggers and manage their symptoms more effectively.<\/p>\n\n\n\n

Here are the common known types of allergy:<\/p>\n\n\n\n

Food Allergy<\/strong><\/h3>\n\n\n\n

Food allergy occurs when the immune system reacts to specific proteins found in certain foods. Common food allergens include peanuts, tree nuts, shellfish, eggs, and dairy products<\/a>. Symptoms of food allergy can range from mild to severe and may include hives, itching, swelling, gastrointestinal distress, and even life-threatening anaphylaxis.<\/p>\n\n\n\n

It is essential for individuals with food allergies to carefully read food labels and be cautious when dining out to avoid accidental exposure to their allergens<\/a>. When accidentally ingested food items that can cause allergy, it’s best to use an epinephrine injection prescribed by your doctor. At the same time, consider visiting the emergency room to prevent the risk of anaphylaxis.<\/p>\n\n\n\n

Skin Allergy<\/strong><\/h3>\n\n\n\n

Meanwhile, skin allergy, also known as allergic dermatitis, occurs when the skin comes into direct contact with an allergen. Common risk factors for skin allergies include certain metals (such as nickel), latex, and certain chemicals found in skincare products. Symptoms may include redness, itching, rash, and blisters.<\/p>\n\n\n\n

Take note that some patients may develop another skin condition due to an allergic reaction. The most common skin conditions are contact dermatitis and atopic dermatitis<\/a>.<\/p>\n\n\n\n

Patients with skin allergies should be mindful of the products they use on their skin, including soaps, lotions, and cosmetics<\/a>. Opting for hypoallergenic and fragrance-free products can help reduce the risk of skin irritation and allergic reactions. Additionally, wearing protective clothing, such as gloves or long sleeves, when in contact with known allergens can provide an extra layer of defense for sensitive skin.<\/p>\n\n\n\n

Respiratory Allergies<\/strong><\/h3>\n\n\n\n

On the other hand, respiratory allergies can occur when allergens are inhaled, triggering an allergic reaction in the respiratory system. Common respiratory allergens include pollen, pet dander, dust mites, and mold spores. Symptoms may include sneezing, runny nose, itchy and watery eyes, congestion, and coughing<\/a>.<\/p>\n\n\n\n
