There are many predisposing factors for decreased immunity, including physiological factors, such as mental factors, malnutrition, smoking and drinking, etc., as well as pathological factors, such as infection, drug suppression, autoimmune diseases, hematologic diseases, etc. Everyone's physique is different, and it is necessary to clarify the cause of the decline in immunity according to their own situation**.
1. Mental factors: patients with long-term work pressure or high work intensity, resulting in excessive tiredness and depression, which will cause endocrine system disorders, resulting in reduced immunity;
2. Malnutrition: If the patient controls the diet for a long time and the nutrients ingested decrease, there will be a decrease in immunity, which is due to the decrease in nutrient intake, resulting in a lack of nutrients for normal protein synthesis and immunoglobulin synthesis in the body. Long-term malnutrition in some patients can also cause deficiency of trace elements such as iron and zinc and vitamins, resulting in anemia. Vitamins and minerals are also involved in the regulation of the immune system, so patients may also experience a decrease in immunity;
3. Smoking and drinking: Nicotine and alcohol contained in tobacco and alcohol will have a huge impact on the liver, and the toxins in the body will increase, which will affect the patient's immunity.
In addition to the above conditions, some patients will also have a decline in their ability to resist diseases due to poor Xi habits, such as less exercise, staying up late for a long time, and reversing day and night.
