Decreased immunity

Introduction The decrease in immunity refers to a decrease in the function of the body's immune system caused by excessive fatigue, excessive consumption of body capital, or a certain primary disease, so that the body is in a state susceptible to infection by bacteria and the like, and is prone to illness. Immunity refers to the "exemption of epidemic disease", which means the prevention of infectious diseases. Biologically speaking, it refers to the ability to resist the development of disease. Immunity is the body's own defense mechanism. It is the body's ability to recognize and destroy any foreign bodies (viruses, bacteria, etc.) that invade. It can deal with aging, injury, death, degeneration of self-cells, and the ability to recognize and treat mutant cells and virus-infected cells in vivo. . Modern immunology believes that immunity is the physiological response of the human body to recognize and eliminate "dissidents."

Cause

First, psychological stress: uneasy, anxious and other psychological fatigue will have adverse effects on the vegetative nerves, while the vegetative nerves and the endocrine system and the immune system are closely related, and the diseases caused by the accumulation are often difficult to cure.

Second, physical fatigue: lack of sleep or overwork, will increase the burden of plant nerves as psychological stress, but also adversely affect the endocrine system and immune system, resulting in decreased immunity.

The third is negative pessimism: too negative and pessimistic personality will cause lower immunity, so it is crucial to maintain a good mood.

Fourth, eating imbalances: eating disorders, irregular eating time, picky eaters, etc. will provide the nutritional deficiencies needed to provide the body's immune system.

Fifth, lack of exercise: lack of exercise leads to physical decline, physical strength can not keep up with it, it is difficult to resist fatigue, which in turn causes immunity to decline.

Sixth, excessive antibacterial: Nowadays, society can provide people with sufficient antibacterial drugs and commodities, but don't over-clean. Once the body's immune system adapts to an environment that is too clean, immunity will decline.

Seven is the body aging: With the increase of age, people recover slowly after illness or are prone to catch a cold, because the body's immune system can not function effectively after aging.

Body function and nutrition

1. Carefully ask the relevant medical history and collect relevant clinical data.

2. Closely check the patient to clearly understand the clinical symptoms of the patient.

3, appropriate physical examination of the patient, a preliminary understanding of the morphological changes of the various organs of the patient.

4. Perform relevant equipment examinations on patients and conduct laboratory tests as appropriate.

5, comprehensive consideration of various inspection results, combined with the clinical symptoms of various organ damage, and finally draw a corresponding diagnosis.

Differential diagnosis

Need to be distinguished from the following symptoms:

Immune damage: in the past decade or two, with the increase in tumor incidence and treatment progress, autoimmune and other immune-related diseases, improved diagnostic and therapeutic levels, organ transplant breakthroughs and development, especially HIV/AIDS epidemics, immunocompromised hosts (immunocompromised host.ICH) is constantly increasing and accumulating, becoming a global challenge. Infection is the most important factor affecting the course and prognosis of ICH. The lung is the main target organ of infection. There are still many problems in the diagnosis and treatment of ICH lung infection, which requires in-depth study. On the other hand, if the existing research results and techniques can be promoted and fully utilized, it is still possible to make the majority of clinical patients diagnose and obtain effective treatment and improve the prognosis.

Immune Deficiency: Immune Deficiency is a kind of repeated infection or serious infectious disease caused by the developmental defects of the human immune system or the immune response disorder, resulting in low anti-infective ability.

Immune defects are classified into primary and secondary types. The former is mainly found in babies and children. If a child has repeated infections after birth, he should go to the hospital to check the immune function to determine if there is an immune deficiency. Children with immunodeficiency cannot be vaccinated with various live vaccines, which may have serious consequences. Immune dysfunction: In the past, because of the lack of examination of immune function during the diagnosis, diagnosis and treatment of diseases, people are more familiar with checking blood sugar, blood rheology, liver function, and are unfamiliar with the immune function test indicators. With the development of medical science and the application of immunoassay technology, targeted examination of immune indicators has become the basis for improving the diagnostic level of immune-related diseases, carrying out targeted treatments, and ultimately improving the efficacy.
