During the long evolutionary process, our hematopoietic system is very well developed and has various mechanisms to protect itself from harm and to provide protection for all organs of the body. However, we should also understand some characteristics of the hematopoietic system and self-care in our life to keep away from hematopoietic disorders. Diet: Anemia or blood cell abnormalities due to micronutrient deficiencies are very common in clinical practice. These include iron, folic acid, and vitamin B12. They provide the raw materials for the synthesis of hemoglobin. If deficient, it can lead to anemia and even an overall decrease in the number of various blood cells. These trace elements are abundant in the normal diet, in picky eaters, prone to deficiencies. For example, vegetarians who do not like to eat meat, eggs and milk are prone to iron deficiency anemia; long-term vegetarians can develop vitamin B12 deficiency anemia. People who like to overcook green vegetables (elderly people have bad teeth) are prone to folic acid deficiency. Pregnant women have an increased need for nutrients because they are carrying a fetus, and if they do not pay attention to supplementation from their diet, they are prone to malnutrition anemia. In our daily life, we should try to eat a balanced diet, not to be picky, and cook reasonably to avoid nutrient loss. For some disease states, such as poor appetite, or chronic diarrhea, bleeding hemorrhoids, excessive menstruation and other diseases that can cause a shortage of hematopoietic materials, it is important to seek medical attention in a timely manner. Here are some misconceptions: 1, expensive food is nutritious. In fact, our daily grains and cereals already contain the nutrients we need. Overly finely processed food instead loses many nutrients. Iron deficiency anemia in economically developed areas such as Zhejiang, but the incidence is high is an example. The unreasonable diet structure is often one of the causes of anemia. 2, often eat health care products, nutritional products can prevent anemia: with the enhancement of health care awareness, many people are attracted to health care products. These years, the health care market in the name of blood supplements a wide range of health care products, the price is not expensive. Such as gum, cordyceps, ganoderma lucidum spore powder, etc., advertising made deep into the hearts of people. In fact, these health supplements do not have the effect of treating diseases. If you are really nutritionally anemic, taking health supplements is not enough; if you are not anemic, if you eat normally, you can prevent anemia and do not need to spend this kind of money. There are also a variety of trace elements of health care products, in fact, the content of trace elements is very low, used for health care may not be harmful, but treatment is not enough, need to be under the guidance of doctors in full dose, full course of supplementation of nutrients. 3, red dates, peanut rice bark can supplement blood: certain foods contain high iron, such as lean meat, eggs, seafood, etc., red dates, peanut rice bark and other iron content is not the highest, if indeed for iron deficiency anemia, may only eat these foods is not enough. As for some patients using the above-mentioned foods to treat leukopenia or thrombocytopenia, there is no basis for this, it is just a comfort in the heart. In fact, the nutrient most closely related to the diseases of our blood system is nutritional anemia. In addition to replenishing the lack of nutrients through medication, it is helpful to increase the diet with foods rich in that nutrient. However, not all blood system disorders can be adjusted by food. I had a patient who had acute leukemia, and he talked a lot about the treatment plan of chemotherapy, and at the end, the patient’s family said, “Doctor, what can I eat to treat leukemia? In fact, for chemotherapy and many blood diseases, as long as you eat well, eat some good digestive, nutritious, clean food can be, the treatment of disease needs to be through drugs rather than “food therapy”. Lifestyle habits Smoking, drinking, overwork, stress, staying up late, and other bad habits can directly and indirectly affect the blood system. Under bad habits, the normal metabolism of the hematopoietic system is affected, and the immune system such as lymphatic system becomes dysfunctional, and over time, various diseases, including blood diseases, will easily occur. On the contrary, keeping a relaxed mood and exercising properly can improve our immunity and make our blood system healthier. Radiation exposure, often the most harmful to the blood system. Long-term close contact with various electrical appliances, contact with ores or gems containing radioactivity, long-term medical exposure, and mistaken exposure to radiation sources in daily life should be avoided as much as possible. Chemical substances: Excessive decoration, close contact with gas stations, air pollution, occupational exposure, poor quality clothing or daily necessities, toxic food or tableware, hair dye, etc., can cause unintentional damage to our blood cells and even hematopoietic failure or cancer. Infection: Various viruses, including EBV, cytomegalovirus, microviruses and many as yet unnamed viruses, can invade the body and cause clinical symptoms as well as genetic mutations in blood cells, even turning into serious blood system diseases. Therefore, to enhance their own physical fitness, avoid repeated “cold”, can reduce the chance of virus invasion into the body. Avoid drug abuse: As the saying goes, “medicine is three times more toxic”, the use of drugs should be under the guidance of a doctor. You should avoid taking health products, Chinese medicine, or imported drugs indiscriminately. I had a patient who was anemic for a long time, but the cause was unknown. Later, it was found out that it was lead poisoning because of the long-term use of Chinese herbal medicines brought back from Hong Kong, which were said to have health effects. Of course, this is an extreme example and you should always be careful to ask your doctor before using any kind of medication. Regular medical checkups General routine medical checkups include routine blood tests, liver and kidney functions, etc., which can help us identify some blood system diseases early. Of course, if you are unwell, or have a family history of hematological disorders, you should always seek medical attention to confirm the disease as early as possible.
