Anemia is divided into three grades according to the degree of hemoglobin reduction. Mild anemia is hemoglobin (Hb? ) Moderate anemia is greater than 90g/L, HB 6090g/L; Hemoglobin of patients with severe anemia is lower than 60g/L. Anemia is the manifestation of many diseases, and its causes are mostly iron deficiency anemia, megaloblastic anemia, malnutrition anemia, thalassemia, aplastic anemia, hemorrhagic anemia, hemolytic anemia and so on.
There are signs of anemia and the patient is in poor health. 1. Paleness is the main manifestation of skin and mucosa in anemia, and the color of skin and lips is white. 2. Symptoms of nervous system, such as dizziness, fatigue, insomnia, tinnitus, memory loss and inattention. It is a common symptom after brain hypoxia, which is caused by anemia and nerve tissue damage. Some symptoms of cardiovascular system, such as palpitation after exercise, lack of air, anemia, etc., are more serious, and the greater the activity, the more obvious the symptoms. In severe anemia, even if you calm down, you may be short of breath. In long-term anemia, compensatory enlargement of the heart may cause anemia heart disease. 4. Symptoms of digestive system, such as abdominal distension, loss of appetite and abnormal stool frequency. Due to gastrointestinal ischemia, digestion and secretion are reduced, glands are atrophied and digestion and absorption are poor.
If anemia occurs, check it immediately to determine the degree of anemia and find out the cause of anemia. In the case of severe anemia, the cause of anemia can be determined at the same time as infusion. Patients with acute massive hemorrhage must actively stop bleeding, at the same time quickly restore blood volume and inject red blood cells to correct anemia. Other anemia patients with unknown causes need bone marrow puncture and biopsy to detect the cause. Iron, folic acid and vitamin B 12 can be supplemented for common iron deficiency anemia or megaloblastic anemia.
