There are three principles for the combined treatment of iron deficiency anemia in Chinese and Western medicine: 1. Iron supplementation: Iron therapy is indispensable, whether or not one takes Chinese medicine. Oral iron is the main method of iron supplementation, commonly used iron: ferrous sulfate, polysaccharide iron complex, etc. To help iron absorption, vitamin C should be added at the same time. dietary iron supplementation is also a method that should not be ignored, for example: use iron pots and pans instead of aluminum pots and pans for cooking utensils; eat more meat foods, fungus, etc. Due to long-term misconceptions, spinach is considered by the public to be high in iron, but in fact, it does not contain much iron. In order not to affect the absorption of iron, you should drink less tea and less coffee. 2, etiological treatment: reduced digestion and absorption, excessive loss, increased demand. Patients with chronic gastritis, enteritis and other digestive tract diseases suffer from iron deficiency due to impaired iron absorption. Excessive iron loss is mainly seen in chronic or recurrent bleeding in the digestive tract, and in women, in excessive menstruation. Increased demand is seen in children and adolescents or in pregnant and lactating women. Treatment of the cause is the first principle in the treatment of iron deficiency anemia. Therefore, male patients must be checked for concomitant bleeding from gastrointestinal diseases, especially peptic ulcers, and middle-aged and elderly patients should be especially alert to gastrointestinal tumors. The most important cause of iron deficiency in female patients of childbearing age is increased menstruation. Gynecological examination and treatment of gynecological diseases are important for effective treatment of iron deficiency. Iron supplementation is often ineffective in the case of increased menstruation. 3.Tonic for the spleen and kidney is a common treatment for iron deficiency anemia in Chinese medicine: Zuo Gui Wan, Gui Spleen Tang, Bazhen Tang, Si Jun Zi Tang and other formulas for the spleen and kidney are all common formulas for iron deficiency. When applying them, you can add or subtract from these formulas according to the four diagnoses of tongue and pulse and the concurrent conditions. Taking Chinese medicine can help relieve the symptoms of anemia, promote iron absorption and utilization, and facilitate recovery from anemia, however, taking Chinese medicine cannot replace iron. The idea and practice of replacing iron with herbal medicine is wrong. The main reasons for poor efficacy after regular iron treatment are: 1. wrong diagnosis, need to re-examine and diagnose. 2. The presence of digestive tract diseases and poor absorption of oral iron supplements. Treatment of digestive tract diseases should be strengthened or switched to intravenous iron supplementation. 3.Continued chronic blood loss.
