Anemia can play a certain role by eating pig liver to replenish blood, but eating pig liver to replenish blood is mainly for iron-deficiency anemia; if it is other causes of anemia, eating pig liver to replenish blood is not effective. 1. Generally speaking, when suffering from iron deficiency anemia, eating pig liver can help to replenish blood, because pig liver is rich in iron, and it has a very good curative effect on microcytic hypochromic anemia caused by insufficient iron intake. However, medication such as ferrous succinate should still be the mainstay of treatment, and food is only supplementary. 2. If there are other types of anemia, such as hemolytic anemia, leukemia, anemia caused by multiple myeloma, eating pig liver may not have much significance in replenishing blood, need to be given to the specific cause of the treatment, such as acute leukemia to be cytarabine and other drugs such as chemotherapy. Therefore, when anemia occurs, it is best to go to the hospital for a systematic examination, according to the different causes, under the guidance of the doctor, choose different treatment methods.
