What disorders are considered diseases of the immune system?

The immune system is a complex defense unit of our body that fights infections, viruses and bacteria and whose mission is to protect us from these attackers. Without the immune system, we would simply be getting sick. Special cells, tissues and organs together form an integral part of our immune system that works constantly – 24 hours a day, 7 days a week, 365 days a year to protect us from various diseases.

The most important, and at the same time the strongest, “army” of our immune system are white blood cells (leukocytes) that are formed from the bone marrow. Leukocytes capture and destroy viruses, bacteria or any other undesirable microorganisms in our body, for which reason their number will be increased when we are sick or certain inflammatory processes are happening in our body.

This type of immune disease occurs from birth. The immune system of children born with this disease is in constant danger of infection by bacteria, viruses and fungi because they are deficient in white blood cells. Severe combined immunodeficiency is sometimes called “bubble boy” disease, after a boy who was forced to live in a sterile environment during the 1970s. “Plastic balloon”.

Temporarily acquired immunodeficiency

It is a condition characteristic of people who have undergone chemotherapy or have used certain drugs that are used as treatment for various cancerous conditions. Also, temporarily acquired immunodeficiency can happen to people after organ transplantation who are on therapy with drugs to prevent rejection of the donated organ. Various infections, such as the flu, mononucleosis and smallpox, can weaken the immune system for a while. The immune system can also be weakened if you smoke, drink alcohol or eat improperly.

HIV / human immunodeficiency virus

This very well-known virus belongs to an acquired infection that attacks white blood cells, which eventually leads to the collapse of the entire immune system of the infected person. People suffering from HIV can get seriously ill from the most harmless diseases, such as the flu or the common cold.

What diseases are caused by an overactive immune system?

If you are born with certain genes, your immune system can react to external substances that are generally harmless. These substances are called allergens. An allergic reaction is the best example of an overactive immune system. Dust, mold, pollen are just some examples of common allergens. Diseases that occur under the influence of allergens are:

Asthma

One of the main causes of asthma are allergens, such as pollen, dust and tobacco smoke. These allergens cause a person suffering from asthma to cough, shortness of breath and other difficulties related to the respiratory system.

Eczema

Many people suffer from eczema, which causes itchy skin known as atopic dermatitis. Allergens are the main cause of this dermatous condition.

Allergic rhinitis

Sneezing and runny nose are the most common symptoms of this disease, which makes your nasal passages swell and swell, most often under the influence of allergens that are found indoors, such as dust, mold and animal hair.

What diseases are autoimmune?

When the body attacks healthy, normal cells, we call this condition an autoimmune disease. The cause of autoimmune diseases cannot be precisely determined, but it is most likely a combination of genetic factors and some external factor that is the trigger for the onset of the disease, for which modern science believes that the cause of autoimmune diseases is, in the most general sense, unknown. The most common autoimmune diseases are:

Type 1 diabetes

The task of insulin is to remove sugar from the blood in order to use it for energy and normal functioning of the organism.

Rheumatoid arthritis

This type of autoimmune disease causes swelling and deformities of all joints in the body, of which those on the hands and fists are most often noticeable. Auto-antibodies called rheumatic factor can
