What is an allergy? Factors, symptoms and ways of treatment

An allergy is a severe immune response to substances that are not naturally dangerous. Common allergens include dead animal skins, pollen from flowers and plants, and bee venom. Of course, anything can be an allergen; it causes a severe reaction of the immune system.

Any substance that causes allergic reactions is called an allergen. Allergens may be present in food, drink, and the environment. Most allergens are harmless and do not affect most people.

If a person is allergic to a substance (such as pollen), their immune system reacts to the substance. As if it is a harmful and dangerous substance and the immune system is trying to destroy it.

Facts About Allergies

Allergies are the result of an incorrect immune response to substances that are usually harmless. The most common allergens are dust, pollen, plants, and nuts. These allergens cause symptoms such as sneezing, vomiting. Anaphylaxis is a very severe allergic reaction that threatens the patient’s life and even causes death—specialists may use a patient’s blood sample to diagnose allergies. However, allergies can only treat by reducing sensitivities. Anaphylaxis requires urgent medical and emergency treatment. Epinephrine injector can lessen the severity of the anaphylactic reaction. When a person with an allergy comes in contact with an allergen, allergic reactions do not occur immediately. The immune system gradually becomes sensitive to the substance and then overreacts.

Allergies may be seasonal. For example, allergic rhinitis or inflammation of the nasal mucosa peaks in the spring because in this season, the amount of pollen in the air is very high.


An allergic reaction causes inflammation and irritation of various organs. Signs and symptoms of allergies depend on the type of allergen. Allergic reactions may occur in the gastrointestinal tract, skin, sinuses, airways, eyes and nose.
Allergic reactions may be confused with the symptoms of other illnesses. For example, spring allergies have symptoms similar to the common cold, but the cause of each is different.

Here are the most important causes and symptoms of each allergy:

Allergy to dust and pollen
Nasal congestion; itchy eyes and nose; runny nose; swollen and teary eyes; cough.

Skin reactions
Scaling; itching; skin rash.

Food allergies
Nausea and vomiting; swollen tongue; numbness and tingling in the mouth; swelling of the lips, face and throat; stomach pain; shortness of breath; rectal bleeding, especially in children; itchy mouth; diarrhea.

Allergies due to insect bites
Swelling at the site of the bite; a sudden drop in blood pressure; itchy skin; shortness of breath and wheezing; restlessness; urticaria, a red, itchy inflammation that spreads throughout the body; dizziness; cough; anxiety;

Allergy to drugs
Swollen tongue, lips and face; skin rash; itching; wheezing; possibility of anaphylaxis.

Anaphylaxis is a rapid allergic reaction that occurs rapidly. This severe reaction may be life-threatening and should be treated urgently. This type of allergic response shows various symptoms within minutes to hours after contact with the allergen. If contact with the allergen is intravenous, symptoms will appear between 5 and 30 minutes later. Food allergens usually take longer to trigger anaphylactic reactions.
The most common areas of the body affected by anaphylaxis are the skin and respiratory system.

Symptoms of anaphylaxis include:

Urticaria throughout the body, itching and burning, swelling of tissues, burning sensation, swelling of tongue and throat, skin discoloration to blue due to lack of oxygen. Also, symptoms such as a runny nose, shortness of breath and wheezing, hoarseness, pain when swallowing, cough. Hypotension causes an increase or decrease in heart rate; abdominal pain; diarrhea; vomiting; loss of urinary control; pelvic pain similar to uterine pain; coronary artery spasm; dizziness and fainting.

Diagnosis of these symptoms is critical to receiving medical care and treatment more quickly.


The most effective way to treat and manage allergies is to avoid allergens.

However, sometimes it is not possible to avoid allergens, and can not be avoided entirely. For example, pollen from flowers and plants is frequently suspended in the air; Especially in spring.

Medications can help treat the symptoms of allergic reactions, but they do not cure the allergy itself. Most allergy medications are over-the-counter. Consult your doctor or pharmacist before taking any medication.
