cd4 belongs to a kind of immune cells, whether this low cd4 cell can be cured needs to be judged according to the cause of the disease, if it is malnutrition, common infections, etc., it can be cured, if it is malignant tumors, etc., it can not be cured. 1. Malnutrition: If the low cd4 is caused by long-term malnutrition, it is possible for the cd4 to return to normal after a period of time of proper supplementation. 2. Infection: If the cd4 is caused by long-term immunity deficiency resulting in respiratory tract, digestive tract and other parts of the infection, then after treatment to remove the original disease, the cd4 can be restored to normal. However, if the decrease of cd4 is due to AIDS, if the treatment time is earlier, then it can be restored to normal; however, if the resistance decreases again, then it may still decrease. 3. Malignant tumors: some malignant tumors may cause low cd4, if the malignant tumors can be cured, then the cd4 can be cured; but if the malignant tumors can not be cured, then the cd4 may not be restored. There are many other reasons for low cd4, and patients need to consult a doctor in time to check the cause of the disease and get early treatment.
