How long it takes to recover from moderate anemia depends on the cause of the anemia, how it is treated, etc., and needs to be analyzed on a case-by-case basis. A hemoglobin concentration of 60-89 g/L is considered moderate anemia. If the moderate anemia is caused by iron deficiency anemia or folic acid or vitamin B12 deficiency, the patient can usually recover in about 2 months after taking iron supplements or folic acid or vitamin B12 and paying attention to diet. If it is caused by aplastic anemia, recovery usually starts around 3-6 months after applying medication. If it is caused by leukemia, myeloma or other blood diseases, the recovery time needs to depend on the specific condition and the treatment plan because systemic chemotherapy is required, so it is impossible to make a generalization. In addition, if patients experience dizziness, headache, fainting and reduced appetite, they can go to the internal medicine and hematology departments of hospitals for blood tests and other related examinations in a timely manner to clarify the cause and provide timely and symptomatic treatment so as not to delay the best treatment time.
