What are the blood diseases? For these 4 types of problems, it is recommended to go to the hematology department

Core reminder: In fact, leukemia is only a classification of hematological diseases. Not all hematological diseases are malignant. They must be distinguished to avoid delay in treatment.

After Xiaoyun moved to a new house, she developed eczema on her body, with small red patches all over her body, as if she had been bitten by hundreds of mosquitoes.

Unbearable, she sent a video call to her sister. Unexpectedly, her sister’s condition was not very good, and her face was covered with a rash because of allergies. "It must be our blood that is poisonous. How many times have I been allergic this year? , Speechless" My sister spit to Xiaoyun.

After listening to her sister, Xiaoyun also remembered that he had read the term blood disease on the Internet before, but he didn't know what it was about.

Statistics show that in 2017, the total number of visits to blood diseases was 282,000, and in 2018 it reached 384,900 . [1] The incidence of blood diseases in China has shown an upward trend year by year.

Blood disease is not equal to leukemia

When many people mention blood diseases, they immediately think of leukemia. In fact, blood disease is not the same as leukemia, there is a subordinate relationship between the two. Common blood diseases are as follows.

Acute leukemia is caused by abnormal proliferation of primitive white blood cells. The clinical manifestations are bleeding, fever, and swollen lymph nodes .

Aplastic anemia . The decrease of hematopoietic tissue leads to failure of hematopoietic function, which leads to the decrease of whole blood cells, resulting in anemia. The clinical manifestations are bleeding and high fever .

Multiple myeloma . This is a malignant tumor with abnormal proliferation of plasma cells in the blood. The clinical manifestations are bone pain , anemia caused by impaired hematopoietic function, etc.

Acute hematopoietic stasis . This disease is generally based on the original anemia, leading to disorders of hematopoietic function, temporary reduction or loss of blood cells. Symptoms are the aggravation of anemia, dizziness, and even shock.

Huang Xiaojun, president of the Hematology Branch of the Chinese Medical Doctor Association and director of the Institute of Hematology, Peking University People's Hospital, said that leukemia is a type of blood disease, and leukemia is a malignant proliferative disease of the blood system . [2]

Leukemia can be divided into several sub-categories, including acute myeloid leukemia and acute lymphocytic leukemia.

These 3 symptoms frequently appear early, beware of blood diseases

In the early stage of blood disease, many symptoms are easily overlooked, thus delaying treatment. Therefore, when the following symptoms appear, be vigilant.

Swollen lymph nodes

In addition to blood diseases, bacterial infections can also cause swollen lymph nodes, so pay attention to distinguish. Leukemia is generally systemic lymphadenopathy, especially in the head and neck, underarms, and groin .

Repeated and persistent fever

Repeated fever is also a common symptom of acute lymphoblastic leukemia, but the temperature of fever is not high , but it repeats intermittently.


Although iron-deficiency anemia is a very common chronic disease, it is generally caused by malnutrition, not by blood lesions. However, it should be noted that many blood diseases are accompanied by symptoms of anemia, such as acute hematopoietic dysfunction, multiple myeloma, etc.

Don't want to come to your door for blood diseases, these 2 kinds of foods are best to stay away

Hematological diseases can be prevented through diet.

Eat less hot foods. If it is a patient with bleeding symptoms, eat less food with sexual heat, otherwise it will worsen the bleeding. Such as lamb, venison, leeks, lychees, etc.

Eat less fatty foods. Excessive fat intake will destroy the body's hematopoietic function and increase the burden on blood vessels. Therefore, the usual diet should be based on light, protein-rich foods.

Eat more foods rich in vitamin C. Lack of vitamin C can lead to decreased blood coagulation and scurvy. Therefore, you can eat more vegetables and fruits to naturally supplement vitamin C.

You can often hear the name of leukemia from movies and literary works, but people know very little about blood diseases. Some people even equate blood diseases with leukemia. In fact, leukemia is only a classification of hematological diseases. Not all hematological diseases are malignant. They must be distinguished to avoid delay in treatment.
