What is Allergy?

An allergy is a reaction of your immune system to a foreign chemical that isn't normally detrimental to your body. Allergens are foreign substances that cause allergic reactions. Certain foods, pollen, and pet dander are examples.

It is the mission of your immune system to keep you healthy by battling hazardous microorganisms. It accomplishes this by attacking anything that it believes poses a threat to your health. This reaction might include inflammation, sneezing, and a variety of other symptoms, depending on the allergen.

Your immune system is designed to adapt to your surroundings. When your body comes into contact with something like pet dander, for example, it should recognize that it is innocuous. The immune system targets dander allergies because it views it as an outside invader posing a threat to the body. Allergies are extremely frequent. Several therapies are available to assist you in avoiding your symptoms.

 Symptoms of Allergies

Several factors contribute to the symptoms you feel as a result of allergies. These factors include the type of allergy you have and its severity. You may still have some of these symptoms if you take any medication before an expected allergic reaction, but they may be less severe.

 Types of allergies

 Food allergy 

Swelling, hives, nausea, exhaustion, and other symptoms of food allergies can occur. It can take a long time for someone to recognize they have a food allergy. If you have a severe reaction after eating anything and aren't sure why, visit a doctor right once. They may be able to pinpoint the source of your reaction or recommend you to an expert.

 Seasonal allergy

The symptoms of hay fever can be mistaken for those of a cold. Congestion, a runny nose, and puffy eyes are among the symptoms. Most of the time, over-the-counter medications can be used to treat these symptoms at home. If your symptoms become unbearable, see a doctor.

 Severe allergy

Anaphylaxis is a life-threatening reaction caused by severe allergies. This is a life-threatening situation that can include difficulty breathing, lightheadedness, and loss of consciousness. If you're having these symptoms after coming into touch with an allergy, seek medical attention right once.

 Skin allergy

Skin allergies can be a symptom or a sign of an underlying allergy. They could also be the result of being exposed to an allergy. Eating a meal to which you are allergic, for example, can trigger a variety of symptoms. Tingling in your mouth and throat is possible. There's a chance you'll get a rash as well.

Touch dermatitis, on the other hand, occurs when an allergen comes into direct contact with your skin. This can happen if you come into contact with an allergen, such as a cleaning product or a plant.

 Causes of allergy

When a typically harmless foreign material enters the body, the immune system triggers an allergic reaction, according to researchers.

There is a hereditary component to allergies. As a result, parents will be able to pass them down to their offspring. Only a general vulnerability to allergic reactions is genetically determined. Specific allergies aren't handed down the generations. For example, just because your mother is allergic to shellfish doesn't guarantee you will be as well.

•  Animal products

 Pet dander, dust mite excrement, and cockroaches are examples.

•  Drugs 

Medications including penicillin and sulfa are common causes.

•  Foods
