what is immunology?

Immunology is, in dictionary terms, the science in which the body is attacked by other organisms but the body's resistance is examined, also called immunity. In medical terms, immunology examines the immune response to the disease-causing microorganisms in the body and the disorders in the functioning of this system. Many hospitals have immunology and allergy disease departments.

The immune system consists of many kinds of molecules and cells distributed in each tissue working regularly to prevent the growth of tumors and to repair damaged tissues, prevent or eliminate microbial infections. It normally recognizes and responds to foreign or damaged molecules.

The innate immune system produces both microbial envelope barriers as well as biochemical or cellular first intervention. This is a very necessary system for living in a world full of micros.

The immune system can play a role in disease formation in three different ways.

1. Activation: The immune system can be active when fighting infections and developing an immune response, resulting in fever, inflammation, and the destruction of the pathogen, which also causes problems. In addition, the immune system registers this pathogen in the memory, creating a more effective response to infection of the same pathogen.

2. Immune deficiency: The immune system can work inadequately, which makes the human body less vulnerable to infections. Immune deficiency can occur because the immune system is deficient in a component or because it stops working because of cancer, drug consumption, or HIV.

3. Hypersensitivity (Allergy): The immune system can be excessively active against harmful substances that come into contact with the body or the body and can work to protect itself. As a result, allergic conditions such as asthma, spring fever or anaphylaxis may occur. Many patients do not have a problem when the allergen is removed from the body, but if allergies are affecting daily life then they should seek medical help.
Immunology What are Diseases?
Many diseases can occur when significant imperfections occur in the immune system or when the immune system has to generate responses that will damage it rather than protect the host cells and tissues.

Immune deficiency diseases become clear due to increased risk of infection and tumor formation, and can occur due to some viruses such as gene mutation, malnutrition, HIV, or cancer treatment. Reactions of the immune system targeting its molecules form autoimmunity, which causes a variety of clinical problems for the respective tissues or organs.

Some immunological diseases can be listed as follows:

Joint inflammation
Long-term Digestion Problems
Type 1 Diabetes
Coronary Inflammation
Allergic Asthma / Bronchitis
Allergic Rhinitis
Pollen, Dust, Food, Insect or Environmental Allergy
How to diagnose?
A disease allergy test is usually performed that shows allergy symptoms. These tests, which can be analyzed in a short time, can be applied from the early ages and do not suffer. During the test, itching and swelling can occur in the area where the test is applied, and besides this, side effects can hardly be seen.

There are two different allergy tests performed on the skin or by taking blood. Suspected allergen in skin tests is applied to the front or rear of the arm, and other allergens can be tested at the same time. If you are allergic to one of these substances, redness or other symptoms in that area indicate this. Sometimes substances or substances considered to be allergens according to the doctor's recommendation are tested by injecting them into your body with a needle.

Immune deficiency diseases other than allergies are usually seen due to genetic reasons. Avoiding air pollution or the hygiene of the living environment or chemically exposure can also cause immune-related diseases. Liver and other organs in the body, such as unexplained growth, rheumatism and allergies, such as the occurrence of diseases such as blood tests can be understood by the diagnosis.
What are the symptoms?
Allergies can be seasonal (such as the pollen allergens that happen in the spring) or all year round. The most common types of allergies can be seen due to food such as grass or grass allergy, dust allergy, mold allergy, allergies to insect bite or eggs, shellfish and nuts or cereals.

Symptoms such as skin irritation, headache, sneezing, runny nose, nausea and diarrhea can be seen from such causes. If you are taking allergen via the nose, your eyes, nose and lungs will probably be affected. However, if the food is allergenic, symptoms may be seen in the mouth, stomach or stomach.

Other immunological diseases are as follows;

Repeated, unusual or difficult infections
Do not lose weight or lose weight
Recurrent pneumonia or pulmonary inflammation, ear inflammation or sinusitis
Multiple antibiotics used in the treatment of infections
Deep abscess or boils that recur in organs or skin
Immune diseases seen in family history
Swollen lymph nodes or growing spleen
Autoimmune diseases
