Aplastic anemia manifests as dizziness, weakness, headache, poor sleep, panic, angina, heart failure changes, and even kidney damage and endocrine system abnormalities, all of which are the result of anemia’s damage to the body’s organs. Aplastic anemia may also result in bleeding or recurrent infections, and the symptoms vary clinically depending on the severity of the anemia. Patients with aplastic anemia are more likely to have infections and bleeding, and anemia is classified as mild, moderate, severe, or critical. If the hemoglobin level is above 9g/100mL, it is called mild anemia, if it is between 6-9g/100mL, it is moderate anemia, below 6g/100mL is severe, and below 3g/100mL is very severe, the same degree as other anemia divisions. Patients with aplastic anemia are prone to infections, so once problems arise, attention should be paid to timely anti-infection treatment. Patients with both moderate and severe anemia need timely blood transfusion treatment to improve the symptoms of anemia, timely follow-up at the hospital for early detection of the severity of anemia as well as early intervention treatment, avoid taking medication at home thinking that the doctor has prescribed it, and also go for regular follow-up to judge the treatment effect by blood routine. Because aplastic anemia is mainly trilineage blood cell reduction, it is necessary to check the control of its condition, early detection of anemia and its severity, and early intervention and treatment, which may be beneficial to the prognosis.
