Mild anemia is defined as a concentration of hemoglobin in the patient’s peripheral blood between 90-120 g/L. Patients with mild anemia also require treatment. Regardless of the type of anemia, if not treated aggressively, mild anemia may further develop into moderate anemia or even severe anemia, thus affecting the patient’s health and safety. For example, in a patient with mild iron deficiency anemia, if not treated aggressively, the patient’s symptoms will persist. Over time, moderate or severe anemia may develop, which can affect the function of the patient’s heart, brain, liver and other vital organs. If a patient with mild anemia develops mild reoccurrence and is not actively treated with drugs such as Conilon and cyclosporine, the patient may further develop into heavy reoccurrence with severe anemia, infection, or even bleeding causing early death of the patient, so even mild anemia needs to be actively treated.
