You can get diabetes from anemia. Anemia is a disease of the blood system in which the concentration of hemoglobin and red blood cells in the blood decreases due to various causes. Anemia can occur for many reasons, including deficiencies in hematopoietic materials such as folic acid, iron, and vitamin B12, hemoglobin disorders, hemolytic anemia, excessive blood loss, and abnormal bone marrow hematopoiesis. Diabetes is a metabolic disease caused by high glucose concentration in the blood. The occurrence of diabetes is related to the reduction of insulin secretion by pancreatic beta cells and resistance to the action of insulin. Anemia and diabetes are two completely different diseases, with different causes, clinical manifestations, and treatments. Patients with anemia can get both diabetes and diabetic patients can also get anemia. In diabetic patients, a deficiency of hematopoietic raw materials leading to anemia often occurs due to an overly strict or overly biased diabetic diet.
