When serum iron is low, it tends to lead to iron deficiency anemia, and symptoms such as dizziness, weakness, and lack of energy may occur. In addition, when blood tests are performed, low hemoglobin may appear, or when serum iron is checked, there is a significant decrease, or a decrease in reserve iron. At this time, attention must be paid to iron supplementation. Iron-rich foods, such as pig liver, egg yolk, and lamb liver, can be appropriately increased in daily life. In addition, you can take direct iron-containing drugs, such as polysaccharide iron capsules, one capsule each time, 1-2 times a day, and insist on taking them for more than a month, which can significantly improve the phenomenon of low serum iron. You can also take traditional Chinese medicine, such as Astragalus, Radix Angelicae Sinensis, Radix Paeoniae Alba, Rhizoma Ligusticum Chuanxiong, which can nourish the blood, invigorate the blood, and improve the low serum iron.
