The immune system is composed of different types of specialized cell, proteins, tissues and organs. Its main function is to detect the damaging microorganisms and destroy them.
When the immune system falsely detects certain allergens despite it’s not harmful for the body, it triggers immune reactions to destroy the “harmful pathogen”.
In this case it’s about the hypersensitive reaction number 1, i.e. allergic reaction. The most common provoker of allergic reaction are:
Some group of people have allergic reaction when they are bitten by some insects (bees, wasps, hornets etc). The symptoms of this reaction can be different- from mild redness to little swelling in the area, nausea, fatigue and mild fever, and in some cases anaphylaxis. Anaphylaxis is acute allergic reaction caused by antigen (the poison from the insect) to which the body is hypersensitive.
Swelling on the face, tongue, mouth and throat, difficult breathing, low blood pressure, itching, change in skin colour, nausea, vomiting, vertigo and go faint are some of the symptoms. If not treated it can result with death.
Most of the people have reaction in their organism to some food products, so often cause for this is food allergy, which in most cases is not true. So you need to distinguish between food allergy and food intolerance. Food allergy is hypersensitive reaction activated by the immune system, which is a response to the certain type of food.
The symptoms are more expressed, in some cases life threatening. There can be swelling on the mouth, tongue, changes on the skin and developing anaphylactic reaction. Food intolerance is non-allergic hypersensitive reaction for which the immune system is not responsible.
The most common food allergens in our country are: eggs, milk, peanuts, wheat flour, soya beans, carrots, strawberries, fish etc.
Condoms, balloons, medicinal gloves and other medicinal material made of latex, rubber material which contains proteins to which some people have allergies.
The allergy may develop from simple contact with the material. Itching and skin redness, possible anaphylaxis are part of the clinical symptoms.
The home dust (or Dermatophagoides pteronyssinus) is a common cause of allergic reactions. The symptoms are sneezing, blocked nose, tears and itching of the eyes.
The prevention includes keeping the home clean, staying away from objects which tend to collect dust, plush toys or objects which are hard to clean from dust, regular change of bedding.
The symptoms of allergic reaction on pollen are not life threatening, but they are not either pleasant. Sneezing, nose itching (rhinorrhea), itching and tears on the eyes are just part of the symptoms people are dealing with.
Drugs allergy is more common than you think it is. If you have allergic reaction to a certain drug, you stop using it. If it’s necessary to take that drug, the doctor should find a suitable replacement.
In case there isn’t another drug, the allergic reaction can only be controlled by antihistamines and corticosteroids, but only if the reaction was not severe.
The most common symptoms are skin changes, face swelling, difficult breathing and anaphylaxis.
People who develop allergic reaction on animals are actually allergic to the proteins in the skin cells (dead skin cells-dandruff), saliva and urine from the animal. In some cases, For this type of allergy sometimes needs a longer period of time (up to 2 years), and the symptoms can drag for months.
Animal allergies are very similar to pollen allergies, but there is the possibility to be symptomatic with difficulty in breathing, chest pressure, lack of air while sleeping etc.
There are many types of mold, and people are allergic to many of them. Mold thrives in moisture, so it can be seen anywhere with dampness- bathroom, vault, kitchen, attic, places where there is a cracked water pipe, lawns or batch of dried leaves etc. The symptoms are similar as the allergies on pollen and home dust.
