The immune system protects the organism against aggressive external agents. Disorders in its functioning consist in incorrect or inappropriate (insufficient or excessive) reactions to the appearance of agents in the body that are considered foreign. Efficient immune system should eliminate such agents as soon as possible, even if they are only potentially dangerous. If the response of the immune system is insufficient, incomplete, delayed or inexistent, we are dealing with immunological deficiency. Primary immunological deficiency is due to congenital genetic defects. However, secondary i.e. acquired deficiencies are more common. In most cases they are transitory and appear often in the initial stages of many infections. Chronic diseases, especially cancer, may permanently damage the body’s defenses. Serious immunological disorders may also be due to spleen removal, which is where antibodies are synthetized. Impaired immunological resistance may be due to certain antibiotics and painkillers. Ultraviolet radiation, bad nutrition, undernutrition, and stress – in particular chronic stress – have a negative impact on the immune system and impair immunological reactions. Many people suffer from AIDS – acquired immunodeficiency syndrome.


If an agent that penetrates into the body is indifferent, that the reaction of the immune system is unnecessary. If it still occurs, we are dealing with oversensitivity or allergic reaction. This type of immunological oversensitivity includes hives, allergic rhinitis, swollen larynx, asthma episodes, and the most dangerous of them all – anaphylactic shock, that is a sudden blood pressure drop and insufficient blood flow to the brain. Agents that may trigger these reactions include different kinds of allergens such as grass and flower pollens, fungus spores etc. Immune system disorders can also consist in treating elements of your own body as foreign and dangerous. Indeed, many blood diseases are manifestation of auto-aggression directed against own blood cells. One of the autoimmune diseases is multiple sclerosis. Lymphocytic leukemia, Hodgkin’s lymphoma and multiple myeloma are the most common types of cancer that affect the immune system.
